Attelabidae, the leaf-rolling weevils

Hazel leaf-roller, Apoderus coryli, subfamily Attelabinae, family Attelabidae.
□ The female Homoeolabus analis and other species in this family lay their eggs on a leaf, and roll up the leaf (like rolling up a rug) with the eggs inside. Entomologists call the leaf roll a nidus. The nidus protects the eggs as well as the larvae that later hatch from the eggs.
Photographed and identified by: Bryan Wenham-Baker. Well done on the ID, Bryan! Location: Ivybridge, South Hams, South Devon, England, UK. Date: 29 July, 2018.

Leaf-rolling weevil (Homoeolabus analis)

Homoeolabus analis (no specific common name), subfamily Attelabinae, family Attelabidae.
□ The hazel leaf-roller is so named because the young live inside rolled-up leaves of hazel trees and shrubs.
Photographed by: Joan Smith. Identified by: KnowYourInsects.org. Location: Tampa, Florida, USA. Date: 9 June, 2017.

Anthribidae, the fungus weevils

Platystomos albinus (no specific common name), subfamily Attelabinae, family Anthribidae.
□ Platystomos albinus may be either dark brown or light brown, but all have a white patch on the snout and at the rear, and two white spots in the middle. The female (shown) has shorter antennae than the male. See the photographer’s story below.
Photographed by: Jennifer Sims. Identified by: KnowYourInsects.org. Location: Jegenstorf, Switzerland. Date: 29 July, 2018.
Jennifer says one landed on her leg, and when she went to touch it, “it suddenly flipped over onto its back and played dead! Very cute!”

Coffee bean weevil, Araecerus fasciculatus, subfamily Choraginae, family Anthribidae.
□ Coffee bean weevils are about the size of a coffee bean, but their common name came about because they often get into stored coffee. They are also a pest of a variety of stored goods and agricultural crops, such as cocoa.
Photographed and identified by: Eric Blehaut. Nicely done, Eric! Location: Bang Krang area of Thailand. Date: 16 August, 2023.

Most weevils have a knuckle-like joint in their antennae, and they can bend them angularly at that joint. Fungus weevils in the Anthribidae family have no such joint, so while they can curve their antennae a bit, they cannot sharply bend them.

Curculionidae, the weevils

Citrus Root Weevil, also known as a Chichi (Diaprepes abbreviatus)

Citrus root weevil, also known as a chichí, Diaprepes abbreviatus, subfamily Entiminae, family Curculionidae.
□ Adult citrus root weevils can be between 10–20 mm (3/8 to 3/4 inches) long, and the color can vary from cream to yellow to dark orange.
Photographed by: Darryl Gracey. Identified by: KnowYourInsects.org. Location: Parrish (south of Tampa), Florida, USA. Date: July 2016.
Darryl says, “I’ve not seen one of these before and had to snap it and research.”

Citrus Root Weevil or Chichi (Diaprepes abbreviatus)

Citrus root weevil, known locally in the Caribbean as a Chichí, Diaprepes abbreviatus, subfamily Entiminae, family Curculionidae.
□ This is a typical appearance of the citrus root weevil: a central dark stripe flanked on each side by a smaller and then a larger stripe.
□ This weevil has become a major pest on Florida citrus since it was introduced to that state in 1964. This one was photographed in the U.S. Virgin Islands. To read more information about this weevil, click here (University of Florida “Featured Creatures” website).
Photographed by: Carlo Castoro. Identified by: KnowYourInsects.org. Location: north side of Saint Thomas, U.S. Virgin Islands. Date: 30 July 2017.
Carlo says, “I found this little guy crawling up the wall in a house.... Thanks for the cool website!” KnowYourInsects.org says, “Glad you like it!”

Citrus root weevil, known locally in the Caribbean as a Chichí, Diaprepes abbreviatus, subfamily Entiminae, family Curculionidae.
□ This particular citrus root weevil lacks the typical striped pattern of this species. Compare it to the others on this page to see the difference.
Photographed by: Marv Goldberg. Identified by: KnowYourInsects.org. Location: Tamarac, Florida, USA. Date: unknown.

Citrus root weevil, known locally in the Caribbean as a Chichí, Diaprepes abbreviatus, subfamily Entiminae, family Curculionidae.
□ The citrus root weevil is a pest on sugarcane too, so it is sometimes called a sugarcane rootstalk borer weevil. In Florida, it is sometimes called an Apopka weevil, because it was originally discovered in Florida in the city of Apopka (near Orlando).
□ The striped pattern on its back can vary. Compare this specimen to the others on this page.
Photographed by: Mike Weyer. Identified by: KnowYourInsects.org Location: Jacksonville, Florida, USA. Date: 15 June, 2020

Citrus root weevil, Diaprepes abbreviatus, subfamily Entiminae, family Curculionidae.
□ The citrus root weevil is sometimes called a diaprepes root weevil after its genus name. Its larvae live underground, where they chew on and damage the roots of citrus trees.
Photographed and identified by: Mark Magers. Nice ID, Mark! Location: Jalisco, Mexico. Date: 30 August, 2023.
Mark says, “What I could find said it was native to the Caribbean and invasive other places.” KnowYourInsects.org says, “Yes, and it is continuing to spread.”

A broad-nosed weevil in the genus Ophryastes, subfamily Entiminae, family Curculionidae.
□ Ophryastes is a genus of broad-nosed weevil that are common to desert areas in the southwestern United States. This one was photographed in southern California.
Photographed by: Juan Jesus Hernadez. Identified by: KnowYourInsects.org. Location: Palm Springs, California, USA. Date: March 2017.

Strawberry Root Weevil (Otiorhynchus ovatus)

Rough strawberry root weevil, Otiorhynchus rugosostriatus, subfamily Entiminae, family Curculionidae.
□ Native to Europe but now found in much of the world, the rough strawberry root weevil gets its name from the larvae, which are fond of the roots of strawberries, berries and other plants.
Photographed and identified to genus by: Kelly McKinne (@gonzonaturalist). Identified to species by: entomologist Robert S. Anderson of the Canadian Museum of Nature. Thank you, Dr. Anderson! Location: northern Ohio, USA. Date: 28 June 2016.
Kelly says, “Found this ‘lifer insect’ in my bathroom today. Very cool!”

Rough strawberry root weevil, Otiorhynchus rugosostriatus, subfamily Entiminae, family Curculionidae.
□ The rough strawberry root weevil is covered with small studs on its rounded pronotum and elytra. With that bumpy surface, it picks up little bits of debris, as seen here.
□ The genus name of Otiorhynchus derives from the Latin terms for ear-snout, referring to the flared nostrils at the end of the snout, which stick out almost like ears. Click on the photo to zoom in and see them. For more on this genus, click here (Otiorhynchus and Peritelus guide).
Photographed and identified by: Thomas Langhans. Nicely done, Thomas! See Thomas’s full-size images here and here. Location: city of San Bruno, county of San Mateo, California, USA. Date: 21 September, 2022.
Thomas says it was about 8 mm (0.3 inches) in length, and he was able to identify it by comparing it to other photos on this page.

Black vine weevil, Otiorhynchus sulcatus, subfamily Entiminae, family Curculionidae.
□ The black vine weevil is sometimes called a cyclamen weevil, cyclamen grub, or European strawberry weevil. They are pests on cyclamen and many, many other plants: the larvae eat the roots, and the adults munch on the leaves.
□ A close look reveals the fine setae (insect “hairs”) on its back. Such a covering of setae is called pubescence. This weevil only gets to be about 11 mm (0.5 inches) long.
Photographed by: Derek Marshall‬‬. Identified by: KnowYourInsects.org.
Location: UK. Date: 23 August, 2020.

Black vine weevil, probably Otiorhynchus sulcatus, subfamily Entiminae, family Curculionidae.
□ This black vine weevil has a lighter color than is typical for this species. This is likely due to its age — as they get older, the color can lighten, so this is probably an old individual, according to entomologist Robert S. Anderson of the Canadian Museum of Nature.
Photographed by: Barb Auge. Identified by: entomologist Robert S. Anderson of the Canadian Museum of Nature. Thank you, Dr. Anderson!
Location: Minnesota, USA. Date: 23 March, 2018.

Black vine weevil, Otiorhynchus sulcatus, subfamily Entiminae, family Curculionidae.
□ The black vine weevil is one of the group of weevils known as broad-nosed weevils that have shorter and broader snouts than most other types of weevils.
□ It is native to Europe, but has spread to North America, where it is now quite common.
Photographed by: Dave Delman. Identified by: KnowYourInsects.org. Location: New York, USA. Date: 13 December, 2017.

Myllocerus dorsatus (no specific common name), subfamily Entiminae, family Curculionidae.
□ Myllocerus dorsatus has a pair of bold white stripes down its head and thorax.
Photographed by: Amit S. Identified to subfamily by: KnowYourInsects.org. Location: Pune, Maharashtra, India. Date: 27 November, 2020.

Sri Lankan weevil, Myllocerus undecimpustulatus undatus, subfamily Entiminae, family Curculionidae.
□ This Sri Lankan weevil made its way from Sri Lanka to Florida in 2000, and now it is in many counties, particularly in the southern half of the state. It looks almost identical to another weevil called the little leaf notcher (Artipus floridanus), which is native to Florida and the Caribbean. Two of the features that set the Sri Lankan weevil apart are a slightly yellowish head (difficult to see here) and spines on its femur (noted with the yellow arrow). For more information on this species, click here (University of Florida “Featured Creatures” website).
Photographed and identified as a weevil by: Marv Goldberg. Identified to species by: KnowYourInsects.org. Location: Tamarac, Florida, USA. Date: 18 January, 2019.

Sri Lankan weevil, Myllocerus undecimpustulatus undatus, subfamily Entiminae, family Curculionidae.
□ The Sri Lankan weevil has characteristic “shoulders.” They are squared off in the Sri Lankan weevil — almost as if it is wearing shoulder pads or military epaulets.
Photographed by: Gail Sciarrone. Identified by: KnowYourInsects.org. Location: Lake Worth, West Palm Beach, Florida, USA. Date: 22 October, 2018.

A broad-nosed weevil in the genus Myllocerus, subfamily Entiminae, family Curculionidae.
Photographed and identified as a weevil by: K J Westman. Tentatively identified to genus by: Mahendran Govindasamy. Thank you, Mahendran! Location: Nithulemada, Rajawella, Kandy, Sri Lanka. Date: 10 January, 2018.
K J says, “It looks like it is some textile toy for kids.”

Fuller rose weevil, Naupactus cervinus, subfamily Entiminae, family Curculionidae.
□ According to North Carolina State Extension, the fuller rose weevil feeds on all sorts of plants from maple and citrus trees to azalea and other flowers, and also is common in the vegetable garden on beans and potatoes. For more information on this insect, click here (North Carolina State University Extension).
Photographed by: Israel Suarez. Identified by: KnowYourInsects.org. Location: Lewisville, North Carolina, USA. Date: 7 December, 2017.
Israel says, “It’s about half a centimeter (0.2 inches) in length.”

Fuller rose weevil, Naupactus cervinus, subfamily Entiminae, family Curculionidae.
□ The Fuller rose weevil reproduces parthogenetically, which means that young can develop from unfertilized eggs. In the mode of sexual reproduction seen in most other animals, a female and a male each provide half the genetic information to produce a viable egg, but in parthogenesis, the female’s eggs already have the full complement of genetic information, so there is no need for a male. In the fuller rose weevil, the female’s young have the exact same genetic complement as she does: they are clones of her, and all are females.
Photographed and identified by: Thomas Langhans. Nicely done, Thomas! See Thomas’s full-size images here and here. Location: city of San Bruno, county of San Mateo, California, USA. Date: 23 October, 2021.
Thomas says it was about 8 mm (0.3 inches) in length, and he was able to identify it with the other photo of this species on this page. Awesome!

White-Fringed Weevil (Naupactus leucoloma)

White-fringed weevil in the genus Naupactus, quite possibly Naupactus leucoloma, subfamily Entiminae, family Curculionidae.
□ White-fringed weevils feed on a wide variety of plants, and can become pests on crops. The adults chew on leaves and the larvae eat roots. For more on white-fringed weevils, click here (University of Florida “Featured Creatures” website).
Photographed by: Laura Knapp. Identified by: KnowYourInsects.org. Location: Arkansas. Date: 21 August, 2023.
Laura says, “I’m in Arkansas where it’s 104°F today and the only things moving are grasshoppers. And this guy climbing on my daughter’s artwork.”

A broad-nosed weevil in the genus Episomus, subfamily Entiminae, family Curculionidae.
□ This broad-nosed weevil looks like it is wearing a knitted sweater. What an amazing texture!
Photographed and identified as a weevil by: K J Westman. Tentatively identified to genus by: Mahendran Govindasamy. Nicely done, Mahendran! Location: Nithulemada, Rajawella, Kandy, Sri Lanka. Date: 11 December, 2018.
K J notes the “textiles” look of this weevil and says, “I find it quite intriguing with dots and dimples.”

A pine weevil in the genus Brachyderes, subfamily Entiminae, family Curculionidae.
□ The photo of this species of pine weevil was taken in the United Kingdom, where two similar species are found. Both are called pine weevils: Brachyderes lusitanicus and Brachyderes incants. Images of the two are available here (Wikipedia) and here (Ukrainian Biodiversity Information Network).
Photographed by: Cee Thompson. Identified by: KnowYourInsects.org. Location: England, UK. Date: 10 May, 2019.
Cee describes this weevil as about 1.2 cm long and 0.5 cm wide (about 1.3 inches long and 0.2 inches wide).

Gold-dust weevil, Hypomeces pulviger, subfamily Entiminae, family Curculionidae.
□ Gold-dust weevils are covered with gold or shiny green scales, but in many, the scales have worn off, leaving the underlying black color to show through
Photographed and identified by: Eric Blehaut. Excellent ID, Eric! Location: Bang Krang area of Thailand. Date: 8 August, 2023.

A broad-nosed weevil, possibly in the genus Catapionus, subfamily Entiminae, family Curculionidae.
Photographed and identified to order by: Shefali Chaudhari. Identified to genus by: KnowYourInsects.org. Location: Navsari Agricultural University, Navsari, Gujarat, India. Date: 10 December, 2018.

Exophthalmus cinerascens (no specific common name), subfamily Entiminae, family Curculionidae.
□ Exophthalmus cinerascens has rows of pink spots along its elytra (the hardened wings covering its abdomen), as well as pink markings on its thorax. In some individuals, the colors are more vibrant.
Photographed and identified as a weevil by: Micaela Della Bruna. Identified to species by: KnowYourInsects.org. Location: Sánchez, República Dominicana. Date: 11 November, 2019.

Imported long-horned weevil, Calomycterus setarius, subfamily Entiminae, family Curculionidae.
□ Native to Japan, the imported long-horned weevil is now very common in much of the eastern United States and southeastern Canada, where they have become agricultural pests on soybeans, alfalfa and other crops.
Photographed and identified as a weevil by: Carolina Torres. Identified to species by: Robert Anderson of the Canadian Museum of Nature’s Beaty Centre for Species Discovery. Thank you, Dr. Anderson! Location: Galesburg, Illinois, USA. Date: 30 June, 2018.

Elytra is the scientific term for the forewings of all beetles (the order Coleoptera). It is a Greek word for sheath, and refers to the forewings’ usually hardened, sheath-like construction. The elytra cover membranous hindwings that are folded below until they are needed for flight.

Green immigrant leaf weevil, Polydrusus formosus, subfamily Cyclominae, family Curculionidae.
□ The round scales give this little green immigrant leaf weevil its brilliant metallic-green color. Some of the scales in this individual have worn off — as they sometimes do — giving a peek at the dark-colored body underneath.
Photographed by: Paul Hinkley. Identified by: KnowYourInsects.org. Location: Grand Rapids, Michigan, USA. Date: 29 August, 2017.

Green immigrant leaf weevil, Polydrusus formosus, subfamily Cyclominae, family Curculionidae.
□ The green immigrant leaf weevil is a tiny weevil at just 5-6 mm (about 0.2 inches) long. This photo shows its clubbed antennae, which is a feature of this species.
Photographed and identified by: Leslie Mertz. Location: Houghton Lake, Michigan, USA. Date: 7 July, 2017.

Green immigrant leaf weevil, Polydrusus formosus, subfamily Cyclominae, family Curculionidae.
□ green immigrant leaf weevils are often associated with yellow birch trees (Betula alleghaniensis), but they can show up just about anywhere: on flowers, on windows, on tables. The photographer spotted this one on a lawn chair in his yard.
Photographed by: Bob McDevitt. Identified by: KnowYourInsects.org. Location: Saint John, New Brunswick, Canada. Date: 1 July, 2020.

Weevil, probably a vegetable weevil, Listroderes costirostris, subfamily Cyclominae, family Curculionidae.
□ Native to South America, the vegetable weevil has been accidentally transported to other parts of the world. One of its most noticeable features is the large rostrum (the “nose”). This weevil will eat a wide variety of vegetables and other plants.
Photographed by: Lynne Nguyen. Identified by: KnowYourInsects.org. Location: Montclair, California, USA. Date: 26 March, 2016.
Lynne says, “I found it on my son’s diaper this morning. (It was a) tad less than 1/4 inch.”

An acorn and nut weevil, quite possibly Curculio pardalis (no specific common name), subfamily Curculioninae, family Curculionidae.
□ The genus Curculio includes more than two dozen species in the United States, and many look quite similar. This could be Curculio pardalis (no specific common name).
Photographed by: Leah Gentry. Identified to genus by: entomologist Robert S. Anderson of the Canadian Museum of Nature. Thank you, Dr. Anderson! Identified to tentative species by: KnowYourInsects.org. Location: Tallahassee, Leon County, Florida, USA. Date: 3 September 2015.
Leah says, “It was on my mailbox this afternoon! Mailbox sits under a water oak and several other trees.”

Acorn and Nut Weevil (Curculio proboscideus)

An acorn and nut weevil, quite possibly Curculio proboscideus (no specific common name), subfamily Curculioninae, family Curculionidae.
□ My what big eyes you have! This is head-on, close-up photo of an acorn and nut weevil displays its almost soulful-looking eyes, as well as the amazingly long snout characteristic of the female of the species.
Photographed and identified by: Amber Bedard. Well done on the ID, Amber! Location: Flint, Michigan, USA. Date: 23 August, 2019.
Amber says, “They are rather cute!” KnowYourInsects.org says, “Great job with the ID, Amber!”

An acorn and Nut Weevil, quite possibly Curculio proboscideus (no specific common name), subfamily Curculioninae, family Curculionidae.
□ This little acorn and nut weevil is just adorable and what a profile! The super-long snout is a characteristic of female: She pokes it into acorns, and once she makes the hole, she lays eggs inside.
Photographed by: Denise Rulason. Identified by: KnowYourInsects.org. Location: Frankenmuth, Michigan, USA. Date: 31 August, 2017.
Denise says, “Interesting bug I have never seen before.... I found her under an oak tree.”

European Curculionid Weevil (Rhinusa tetra)

European curculionid weevil, also known as a mullein weevil, Rhinusa tetra, subfamily Curculioninae, family Curculionidae.
□ The European curculionid weevil is native to Europe, and parts of Asia and Africa, but is also now found in North and South America. It also goes by the name mullein weevil, because it eats the plant common mullein (Verbascum thapsus), a plant with large, soft, and fuzzy leaves (also sometimes jokingly called nature’s toilet paper).
□ Characteristics of the European curculionid weevil include the covering of short setae (insect “hairs”), and the beefy-looking femora (thighs).
Photographed by: Dave Delman, M.D. Identified by: KnowYourInsects.org. Location: Roslyn, New York, USA. Date: 10 June, 2018.

Graptus triguttatus (no specific common name), subfamily Curculioninae, family Curculionidae.
□ Graptus triguttatus has a V-shaped marking toward the rear of its elytra, and an additional two broad blotches of lighter color toward the middle. These markings are rather faint on this individual, but they are more pronounced on others.
Photographed by: Yanni Petropoulos. Identified by: KnowYourInsects.org. Location: mainland of southwestern Greece. Date: January, 2021.

Unidentified weevil, possibly in the tribe Mecinini, subfamily Curculioninae, family Curculionidae.
□ One possibility for the identification of this weevil is the tribe Mecinini. Members of this tribe are covered with setae (insect “hairs”) on its pronotum (the shield covering its thorax). The setae look to be almost parted and combed.
Photographed by: Anne Bannatyne. Identified to family by: KnowYourInsects.org. Location: west Scotland, UK. Date: 15 August, 2021.
Anne found this weevil along a coastal path.

White-margined weevil, Lixus albomarginatus, subfamily Lixinae, family Curculionidae.
□ The species name of this white-margined weevil is albomarginatus, which literally means white-margined. It has a flattened and oval silhouette and a slightly downward-curved snout, as do other members of the genus Lixus.
□ Note: It is sometimes listed under its older genus name Compsolixus.
Photographed by: Yanni Petropoulos. Identified by: KnowYourInsects.org. Location: mainland of southwestern Greece. Date: 30 April, 2020.

Weevil, Coniocleonus pseudobliquus, subfamily Lixinae, family Curculionidae.
□ The brown swoosh marks help identify this species of weevil. It is usually found in dry areas, and lives throughout southern Europe and east into Turkey and Iraq.
Photographed by: Yanni Petropoulos. Identified to species by: KnowYourInsects.org. Location: mainland of southwest Greece. Date: 22 June, 2022.
Yanni says, “I liked the beetle as it camouflaged so well on the ground. Must have been of old age, as it was missing a leg.”

Red palm weevil, Rhynchophorus ferrugineus, subfamily Dryophthorinae, family Curculionidae.
□ The red palm weevil comes in a variety of colors (including black with a red stripe), but this rust-colored variation is quite common in Cyprus where this photo was taken. These weevils can grow to about 3.3 cm (1.3 inches) long.
□ The red palm weevil is native from southern Asia and over to Papua New Guinea and nearby islands, but has now spread to other warm climates. For instance, it was first reported in southern California in 2010, but after a concerted effort to find and get rid of it, it was declared eradicated in January 2015 (University of California Riverside Center for Invasive Species Research).
Photographed and identified by: Katherine Toumbourou. Well done on the ID, Katherine! Location: Nicosia, Cyprus. Date: 16 May, 2018.
Katherine says, “Your wonderful website helped me identity a bug that flew through my window today.” She adds, “They’re a real problem both here and in the Middle East, and are classified as pests.”

Red palm weevil, Rhynchophorus ferrugineus, subfamily Dryophthorinae, family Curculionidae.
□ These photos show the top and bottom views of this red palm weevil. Some individuals have fewer spots on the thorax, as shown elsewhere on this page. Notice the tiny red balls up near the head in the bottom view — they are phoretic mites (related to ticks and spiders) that use insects like buses: They climb aboard, take a ride, and hop off.
Photographed and identified to order by: Yanni Petropoulos. Location: On the mainland, Southwest Greece. Date: 19 April, 2020.
Yanni says, “Took a photo of this beautiful insect today (it visited our balcony). When I checked on it again after 5 minutes, it was upside down and pretending dead! I flipped it and after a while started moving again.”

Red palm weevil, larva, Rhynchophorus ferrugineus, subfamily Dryophthorinae, family Curculionidae.
□ The larvae of the red palm weevil feed on the interior of palm tree trunks, and if the tree has a substantial infestation of larvae, they can cause so much damage that the trunk may break. Often the larvae gnaw loud enough that they can be heard from a few feet away.
Photographed and identified by: Eric Blehaut. Thank you for the ID, Eric! Location: Prasat Nakhon Luang, Nakhon Luang, Thailand. Date: 5 May, 2022.

A billbug in the genus Sphenophorus, possibly Sphenophorus latinasus (no specific common name), subfamily Dryophthorinae, family Curculionidae.
□ The billbug, named for its long snout or “bill”. Little has been written about Sphenophorus latinasus (no specific common name), which suggests that it has not been found to be a major agricultural or landscaping pest (the squeaky wheel gets the grease!). More attention has been paid to a related species, called a bluegrass billbug (Sphenophorus parvulus) that is a pest in lawns.
Photographed and identified to family by: Marv Goldberg. Identified to species by: KnowYourInsects.org. Location: Tamarac, Florida, USA. Date: 25 May, 2020.

Palmetto weevil, Rhynchophorus cruentatus, subfamily Dryophthorinae, family Curculionidae.
□ Considered the largest weevil in North America, the palmetto weevil can grow to about 1.25 inches long (3.1 cm). This species has quite a bit of variability. For instance, this individual has considerable black markings on its head, while others have very little black on their heads, and still others are completely black. For more information on this pretty weevil (and to see some the variation in this species), click here (University of Florida “Featured Creatures” website).
Photographed by: Jordan Knepper. Submitted by:Doug Knepper. Location: Tampa, Florida, USA. Date: 10 March, 2018.

Banana stem weevil, Odoiporus longicollis, subfamily Dryophthorinae, family Curculionidae.
□ As an adult, the banana stem weevil may be 2.3-3.9 cm (1-1.5 inches) long, so they have quite a size range. They are pests of bananas, as well as plantains.
Photographed and identified to order by: Rukyya Siddique. Identified to species by: KnowYourInsects.org. Location: Pauri district Uttrakhand, India. Date: 9 June, 2020.

Rice weevil, Sitophilus oryzae, subfamily Dryophthorinae, family Curculionidae.
□ Rice weevils infest rice as well as several other grains, such as wheat and corn, and are sometimes known by the name lesser grain weevils. Check out the comment below.
Photographed by: Jim Coolbaugh, a retired U.S. Navy infectious disease research microbiologist. Identified by: KnowYourInsects.org. Location: in the sea near Malaysia. Date: 24 November, 2017.
Jim says, “We are on a sailboat in Malaysia, and have an infestation of these insects. They are about 2 mm (0.8 inches) long, and they fly.” In an update, Jim says they found the source of the infestation: “They are coming from some stored, and thought-sealed pasta.... Out you weevils!”

Rice weevil, Sitophilus oryzae, subfamily Dryophthorinae, family Curculionidae.
□ These close-up photos show excellent detail of this small rice weevil, even the punctate (dimpled) surface of the body and wings.
□ Adult female rice weevils will make a little hole in a bit of grain or a bean, deposit an egg inside, and then secrete some soon-hardening fluid over the hole to seal in the egg. The egg hatches, the larva begins eating the contents of the seed or bean, and when it becomes an adult, it chews its way out.
Photographed by: Amit Upadhyay. Identified by: KnowYourInsects.org. Location: Navi Mumbai, India. Date: 9 July, 2021.

Granary weevil in the genus Sitophilus, subfamily Dryophthorinae, family Curculionidae.
□ Granary weevil is a generic name for a number of small weevils that infest grains, such as rice, wheat and corn, as the photographer discovered. Two of the most common are the rice weevil (Sitophilus oryzae) and the wheat weevil (Sitophilus granarius.
Photographed by: Robert E. Hilson. Identified by: KnowYourInsects.org. Location: Bath, Ontario, Canada. Date: 17 March, 2021.
Robert found this weevil “in my kitchen after opening a frozen pumpkin-pecan pie and leaving it to thaw.” He adds, “We also discovered that our pet cat ‘Mr. Rusty Roufus’ is very good at detecting them.”

Agave or Sisal Weevil (Scyphophorus acupunctatus)

Sisal weevil, sometimes called an agave weevil, Scyphophorus acupunctatus, subfamily Dryophthorinae, family Curculionidae.
□ This weevil is known as a sisal weevil because its host plant is a type of agave called sisal (Agave sisalana), which is often used to make twine or rope.
□ Note: This is now listed as part of the subfamily Dryophthorinae, which falls under the family Curculionidae. At one time, the Dryophthorinae was listed as its own family: Dryophthoridae.
Photographed by: Carlo Castoro. Identified by: KnowYourInsects.org. Location: St. Thomas, U.S. Virgin Islands. Date: 7 January, 2018.

A weevil possibly in the genus Scyphophorus, subfamily Dryophthorinae, family Curculionidae.
□ This weevil could possibly a member of the genus Scyphophorus. This individual was photographed on a cucumber plant, but it is not known particular cucumber pest. Unfortunately, keys and other identification resources for weevils in India are difficult to come by, so it remains only tentatively identified.
Photographed and identified to family by: Surabhika Panda. Identified to tentative genus by: KnowYourInsects.org. Location: Gunupur, Odisha, India. Date: 28 August, 2020.

Asian ambrosia beetle, Xylosandrus crassiusculus, subfamily Scolytinae, family Curculionidae.
□ The Asian ambrosia beetle (Xylosandrus crassiusculus) has spread around the world. This one was photogrtaphed in Jordan. It is known as a pest species because the adults and larvae infest a variety of fruit and hardwood trees. See the comment below.

Mohammed collected these beetles from a “nearby forest on infected oak and pine trees.”

A snout weevil in the genus Neoerethistes, subfamily Molytinae, family Curculionidae.
□ Check out the curved snout on this handsome snout weevil. The tan-colored speckles on its back almost look like it was sprinkled with sticky sand.
Photographed by: Donna Sánchez. Identified to genus by: Macotulio Soto-Hernández, Instituto de Ecología, México. Location: Malinalco, México. Date: 9 July, 2017.

Sternuchopsis fabricii (no specific common name), subfamily Molytinae, family Curculionidae.
□ Sternuchopsis fabricii is a handsome beetle with cream-colored markings on each side of its thorax and cream-colored rectangles on the reddish-and-black elytra (the hardened wings covering most of its back). Even the ridges on its elytra and small divots on its legs show up in this photo.
Photographed by: Yashraj Thakare. Identified by: KnowYourInsects.org. Location: Dombivli East, Thane, Maharashtra, India. Date: 26 October, 2023.

Conotrachelus posticatus (no specific common name), subfamily Molytinae, family Curculionidae.
□ Conotrachelus posticatus has two little white dots on the back (just visible here). Some individuals will also have a light-colored band near the rear end. This one was on the blue tarp of a jump house (see comment below).
Photographed and identified to family by: Stephen Brown. Identified to species by: KnowYourInsects.org. Location: Houston, Texas, USA. Date: 23 April, 2020.
Stephen and his family spotted a whole collection of these weevils in the yard. He says, “We were just amazed at how many we saw after deflating the jump house.”

Cholus zonatus (no specific common name), subfamily Molytinae, family Curculionidae.
□ Cholus zonatus has bands across its elytra (the hardened forewings covering most of its back). In some individuals, the bands are almost solid color, but in others (as seen here), the bands are more mottled.
Photographed and identified by: Ron Andrew. Well done on the ID, Ron! Location: St. Lucia. Date: 31 January, 2021.

A snout weevil in the genus Cholus, subfamily Molytinae, family Curculionidae.
□ This genus (Cholus) of snout weevil has many species, all a bit different in pattern — some with speckles (seen here), and some with spots, stripes or bands — but all have the same general body shape, including the long, curved snout. This one also has an orange-yellow ventral side.
Photographed and identified by: Paul Davis. Well done on the ID, Paul! Location: Borinquen Mountain Resort, Costa Rica. Date: 2016.

Weevil in the genus Brachycerus, subfamily Brachycerinae, family Curculionidae.
□ Weevils in this genus — Brachycerus — have sculpted backs. This one is reminiscent of an alligator. Most weevils have noticeably elbowed antennae, but this species has an unusual arched shape to each of its antennae. One of the species in Greece, where this photo was taken, is Brachycerus rufipes, but the term rufipes means red-footed (actually referring to its red claws), and this one has black claws. Click on the photo above to zoom in and see the claws.
Photographed by: Yanni Petropoulos. Identified by: KnowYourInsects.org. Location: mainland of southwestern Greece. Date: 30 April, 2020.

Rose curculio, Merhynchites bicolor, subfamily Rhynchitinae, family Curculionidae.
□ The rose curculio is mainly brick-red in color, but with black legs and a long, black proboscis. Another feature of this weevil is its pair of antennae. Most other weevils have antennae with a hinged joint so they can sharply bend like an elbow, but the rose curculio does not (no hinge, so sharp bending).
Photographed by: Dave Delman, M.D. Identified by: KnowYourInsects.org. Location: Roslyn, New York, USA. Date: 10 June, 2018.

Learning a bit of Latin can be useful. For example, maculatum is Latin for spotted, and many spotted insects have scientific names that include the word maculatum. Similarly, the Latin word for snout is rhynch, so a scientific name containing rhynch suggests the insect’s snout is an identifying feature.

Brentidae, the primitive weevils

Oak timberworm weevil, Arrhenodes minutus, male, subfamily Brentinae, family Brentidae.
□ To tell an adult male from an adult female oak timberworm weevil, look at the mouthparts. This male has a rather robust pair of jaws, whereas the female has an much narrower, elongate, tube-shaped beak.
Photographed by: Ray Chin. Identified by: KnowYourInsects.org. Location: Toronto, Canada. Date: 7 January, 2018.

Oak timberworm weevil, Arrhenodes minutus, male, subfamily Brentinae, family Brentidae.
□ The oak timberworm weevil gets its common name from the larvae, which look rather like worms and will bore into wood, especially oak.
Photographed by: Mary Freelove. Identified by: entomologist E. Richard Hoebeke with the University of Georgia Extension. Thank you, Rick! Location: northern Georgia, USA. Date: 30 April, 2016.

Oak timberworm weevil, Arrhenodes minutus, male, subfamily Brentinae, family Brentidae.
□ This adult oak timberworm weevil has a little less of the yellow markings on its elytra (the hardened wings covering most of its back) than is typical of this species.
Photographed and identified to order by: Jaymie Miller. Identified to species by: KnowYourInsects.org. Location: middle Tennessee, USA. Date: 19 May, 2019.

Oak timberworm weevil, Arrhenodes minutus, female, subfamily Brentinae, family Brentidae.
□ This is the female Oak timberworm weevil, which has differently shaped jaws than the male (pictured elsewhere on this page). They are ideal for digging tiny tunnels into the wood of oaks and other trees. She then lays one egg in each hole and and seals it up with a glue-like secretion mixed with her frass (feces). The larvae hatch and feed on the wood until they become adults.
Photographed by: Gina Marie. Identified by: KnowYourInsects.org. Location: New Jersey, USA. Date: 9 June, 2021.

Lymexylidae, the ship timber beetles

Ship timber beetle (Atractocerus brasiliensis)

Atractocerus brasiliensis (no specific common name), female, subfamily Atractocerinae, family Lymexylidae.
□ These photos show the wings and the abdomen of a female Atractocerus brasiliensis, as well as what appear to be fungal spores in a sac at the rear of her abdomen. The female lays eggs in tunnels in wood (or under bark) and does a bit of farming: she deposits some of the fungal spores into the tunnels, the fungus grows, and her hatching larvae survive by eating the fungus.
□ The photographer described it as approximately 2 inches (5 cm) long.
Photographed by: Andi Dokats. Identified by: KnowYourInsects.org. Location: Elias Calles, north of Cabo San Lucas, Baja California. Date: 21 June, 2022.
Andi says this was photographed in the desert “about a thousand miles south of San Diego.”

Unidentified ship timber beetle, family Lymexylidae.
□ Ship timber beetles often hold their abdomens in a curled-up position as seen here. Notice the blue eyes on this one, and also that its hardened forewings (called elytra) are tiny nubs, so its membranous hindwings are showing. In most beetles, the elytra fully cover the hindwings when they are not in use for flight. Click on the photo to zoom in and see the elytra.
Photographed by: Sarah Park. Identified by: KnowYourInsects.org. Location: Bangui, Central African Republic. Date: 16 August, 2021.
Sarah says, “When I tried to get it to go on a piece of paper so I could bring it inside to get a better look at it, it clung to the screen, and flapped its mini-dragonfly sort of wings.”

Ship timber beetle, eggs, larvae and adult, family Lymexylidae.
□ Note the very unusual — and huge — eyes on the adult ship timber beetle in the two left photos. The bottom left photo shows just how long this beetle’s abdomen is.
□ The right photo is an aggregation of the ship timber beetle’s eggs and hatching larvae. Although they are called ship timber beetles, these insects will bore into living trees in addition to the wood of ships and other structures.
Photographed by: Jorge “Izzy” Irizarry. Identified by: KnowYourInsects.org. Location: Puerto Rico. Date: 29 September, 2015.
Of the adult, Jorge says it “was very loud when flying. It died, but before it did it laid around 100 eggs.”

Trogossitidae, the bark-gnawing beetles

Bark-Gnawing Beetle (Temnoscheila chlorodia)

Temnoscheila chlorodia (no specific common name), subfamily Trogossitinae, Trogossitidae.
□ Temnoscheila chlorodia is a member of the bark-gnawing beetle family. It has a characteristic little crease on its head between the eyes.
Photographed and identified by: Robert E. Carpenter. Well done on the ID, Robert! See Robert’s slow-motion insect videos here. Location: Kerrville, Texas, USA. Date: 15 December, 2016.
Robert says, “Found under bark of dead box elder tree (Acer negundo).”

Temnoscheila chlorodia (no specific common name), subfamily Trogossitinae, Trogossitidae.
□ Temnoscheila chlorodia has a metallic appearance, and may be green, purplish-black, or bluish-black.
Photographed by: Aven Wright McIntosh. Submitted by: Preston French. Identified by: KnowYourInsects.org. Location: Eugene, Oregon, USA. Date: 25 May, 2020.

□ Many species of bark-gnawing beetles (in the family Trogossitidae) are fungus-eaters, and search for food by looking under tree bark or boring tunnels into wood.

Cleridae, the checkered beetles

Red-legged ham beetle, Necrobia rufipes, subfamily Korynetinae, family Cleridae.
□ A small insect at just 4.5 mm long (less than 0.2 inches), the red-legged ham beetle has a metallic blue-green back and reddish-brown to orange legs. Its antennae are also reddish-brown to orange with black, clubbed tips. This little beetle has a varied diet that includes dried fish and fly larvae/maggots, according to the Food and Agriculture Organization of the United Nations.
Photographed by: Suzanne Cuomo. Identified by: KnowYourInsects.org. Location: Wyckoff, New Jersey, USA. Date: 22 March, 2019.

Red-legged ham beetle, Necrobia rufipes, subfamily Korynetinae, family Cleridae.
□ The photographer reports finding larvae of the red-legged ham beetle in a bag of dog food, and the adults nearby. These beetles eat meat products, particularly dried meat, and have been known to get into dog food and also pet stores. They are also pests in natural history museums, where they nibble at taxidermy mounts.
Photographed by: Gina Mastrogiovanni. Identified by: KnowYourInsects.org. Location: New Jersey, USA. Date: 16 September, 2019.

Ant beetle, also known as a European red-bellied clerid, Thanasimus formicarius, subfamily Clerinae, family Cleridae.
□ The ant beetle has strong jaws perfect for its diet: It crunches through the carapace of adult bark beetles (in the family Scolytidae), often first nipping off the bark beetles’ legs so they cannot run away. Ant beetles will also eat the larvae of bark beetles.
□ The ant beetle will also use its strong jaws in self-defense (see comment below).
Photographed by: Howard Toon. Identified by: KnowYourInsects.org. Location: Hathern, England, UK. Date: 22 March, 2019.
Howard says it was about 10 mm (0.4 inches) long. He adds, “I just felt a bite or a sting on my neck and caught this insect.”

Melyridae, the soft-winged flower beetles

Soft-winged flower beetle, Cordylepherus viridis, subfamily Malachiinae, family Melyridae.
□ This species of soft-winged flower beetle is very similar to a malachite beetle (Malachius bipustulatus), but it has more of a blue tint (rather than green), and a longer and more squared-off pronotum (the shield covering its thorax). In addition, it lacks any touch of red on the edges of the pronotum, while malachites sometimes have this feature. For a nice comparison of the two species, which both have two spots at the tips of their elytra (the hardened forewings covering most of its back), click here (Beetle Fauna of Germany/Kerbtier.de).
Photographed and identified to family by: Eric Bleheut. Identified to species by: KnowYourInsects.org. Location: Lille, France. Date: 11 June, 2023.

Soft-Winged Flower Beetle (Anthocomus equestris)

Anthocomus equestris (no specific common name), subfamily Malachiinae, family Melyridae.
□ Anthocomus equestris is an import to North America, where this photo was taken. It is a native Eurasian species.
Photographed by: Susan Reinhardt. Identified by: KnowYourInsects.org Location: Bel Air, Maryland, USA. Date: 3 June, 2017.
Susan says, “This is an enlarged photo taken with my iPhone. To the naked eye it is much smaller and is long and thin.”

Anthicidae, the antlike flower beetles

Monoceros beetle, Notoxus desertus, subfamily Notoxinae, family Anthicidae.
□ The “horn” projecting forward over the head is a giveaway for the monoceros beetle. This beetle is one of the group often described as ant-like. In fact, the submitter described it as about the size of a pea or “small like an ant.” This beetle has two black spots on its back, plus a V-shaped band. See the description in the comment below.
Photographed by: Autumn Highstreet. Submitted by: J. H. Highstreet. Identified by: KnowYourInsects.org. Location: Michigan, USA. Date: 17 June, 2019.
J. H. says, “We have named it the Minecraft bug, since it looks like the creeper face in minecraft.”

□ Many species in the subfamily Notoxinae contain the poisonous substance called cantharidin, which helps defend them against predators. This substance is also found in oil beetles in the family Meloidae.

AntLike Flower Beetle (Ischyropalpus spp.)

An antlike flower beetle in the genus Ischyropalpus, subfamily Anthicinae, family Anthicidae.
□ This shiny antlike flower beetle has deep-red hues on its rather lightbulb-shaped thorax (bulbous at the front and narrower at the rear), and long antennae.
Photographed and identified by: Eric Blehaut. Location: Bang Krang area of Thailand. Date: 14 October, 2023.

Tenebrionidae, the darkling beetles

Desert ironclad beetle, Asbolus verrucosus, subfamily Pimeliinae, family Tenebrionidae.
□ The desert ironclad beetle is sometimes called a blue death-feigning beetle because it has a bluish tint in the right lighting, and because of its interesting defensive strategy: it rolls onto its back, sticks its legs out, and becomes rigid. Its tough exoskeleton plus the lack of movement usually makes predators lose interest, and once the coast is clear, the beetle loosens up, flips over, and continues on its way.
□ Although its common name is desert ironclad beetle, it is actually in the darkling beetle family (Tenebrionidae), and is not related to the ironclad beetle family Zopheridae.
Photographed by: Vanessa and Mike Perez. Location: south of Phoenix, Arizona, USA. Date: 26 September, 2020.
Vanessa and Mike say, “We found this in our backyard and have never seen anything like it.”

Morica planata (no specific common name), subfamily Pimeliinae, family Tenebrionidae.
□ Most beetles raise their hardened forewings (called elytra), unfold the pair of membranous flight wings that lie underneath, and fly away. With Morica planata, however, the elytra are fused, and they cannot fly. Notice this species’ characteristic flattened pronotum (the shield covering the thorax). Photographed and identified to order by: Sanne Houwing. Identified to species by: KnowYourInsects.org. Location: Tibi, Valencia, Spain. Date: 14 June, 2018.
Sanne says, “We encountered this flatheaded fellow at breakfast in Spain.”

A darkling beetle in the genus Ocnodes, possibly Ocnodes scabricollis (no specific common name), subfamily Pimeliinae, family Tenebrionidae.
□ Like other members of this family, this darkling beetle’s antennae each have 11 segments; has big compound eyes that are each notched by a ridge (visible between the eye and the antenna in this photo); and a 5-5-4 arrangement of its tarsus (the last part of the leg before the final claw), which means that the tarsus of both its front and middle leg each have five segments, and the hind leg has four segments.
Photographed and identified to order by: David Meredith. Identified to tribe (Sepidiini) by: KnowYourInsects.org. Identified to genus and tentative species by: Marcin Jan Kamiński, Museum and Institute of Zoology of the Polish Academy of Sciences. Thank you, Dr. Kamiński! Location: Botswana, Africa. Date: November 2019.

A darkling beetle in the subfamily Pimeliinae, family Tenebrionidae.
□ Although it may look a bit like a squirrel storing nuts in its cheeks, the exaggerated sideward extensions of this darkling beetle’s head are a permanent part of its overall impressive structure.
Photographed by: Quintin Naude. Submitted and identified to suborder by: Dawid Naude (Quintin’s father). Location: Kuzuko Lodge, Eastern Cape, South Africa. Date: 17 February, 2019.
KnowYourInsects.org is thrilled when families work together! Great job, Quintin and Dawid!

Phaleria bimaculata (no specific common name), subfamily Diaperinae, family Tenebrionidae.
□ The species name Phaleria bimaculata is bimaculata, which means two spots. Although they are faint on this individual, the spots are visible against the lighter brown of its elytra (the hardened forewings covering most of its back) are much more pronounced.
Photographed by: Yanni Petropoulos. Identified by: KnowYourInsects.org. Location: mainland of southwest Greece. Date: 8 August, 2021.

A darkling beetle, probably in the genus Eleodes, subfamily Tenebrioninae, family Tenebrionidae.
□ Darkling beetles are sometimes called clown beetles, because of their habit of running around rather crazily (see the photographer’s comment below) and sometimes doing a headstand when they are threatened (note: another group of beetles is also known as clown beetles &mash; see the section on Histeridae). They are also sometimes called stink beetles because one of their defensive mechanisms is to emit a smelly secretion from their rear ends.
Photographed and identified to order by: Thomas Langhans. Identified by: KnowYourInsects.org. See Thomas’s full-size images here and here. Location: city of South San Francisco, county of San Mateo, California, USA. Date: 28 April, 2017.
Thomas says, “This one was in a real hurry to get somewhere. It was large, I can only guess now, perhaps about 4 cm (1.6 inches).”

A flour beetle in the genus Tribolium, subfamily Tenebrioninae, family Tenebrionidae.
□ Among the several species of flour beetle, two are especially common in houses just about everywhere in the world: the red flour beetle (Tribolium castaneum) and the confused flour beetle (Tribolium confusum. These tiny beetles look almost identical, and both feed on flour and other grains people store in the pantry. For more information about these beetles, click here (University of Florida “Featured Creatures” website).
Photographed by: Fatima Amer. Identified by: KnowYourInsects.org. Location: Dammam, Eastern Province, Saudi Arabia. Date: 18 March, 2019.
Fatima says it was about 4mm (0.15 inches) long. She has discovered a few in her apartment. KnowYourInsects.org says, “They are definitely good at sneaking into homes!”

Frantic surface beetle in the genus Zophosis, subfamily Tentyriinae, family Tenebrionidae.
□ As their common name suggests, frantic surface beetles are very active, notably in the hot midday sun when just about every other living thing is hidden away. (See comment below.) According to a Journal of Tropical Ecology article, they only seek cooling shelter when their body temperature reaches near-lethal levels.
Spotted by: Declan Rademan. Photographed by: Neil Rademan. Identified by: KnowYourInsects.org. Location: Clanwilliam, Western Cape, South Africa. Date: 23 November, 2020.
Neil says his son Declan had to chase this little beetle, which was “running around frantically.” He adds, “(Declan) got all excited about this tiny blue beetle.” KnowYourInsects.org says, “We are excited, too! Great find!”

Rough-haired lagria beetle, Lagria hirta, subfamily Lagriinae, family Tenebrionidae.
□ The rough-haired lagria beetle is covered with coarse setae (insect “hairs”), which are particularly noticeable on its elytra (the hardened forewings covering most of its back). Besides all the setae, the reddish elytra contrasted with the dark, shiny thorax and head are good identifying features for this beetle.
□ Long and jagged antennae like those of this beetle are known as serrate antennae.
Photographed and identified by: Eric Blehaut. Well done on the ID, Eric! Location: Lille, France. Date: 22 June, 2023.

Many of the species in the Tenebrionidae family are active only at night and therefore rarely seen. These nocturnal habits give rise to their common name of darkling beetles. Tenebrionidae also contains the Latin word tenebrion, which means darkness or lover of darkness.

A darkling beetle in the genus Strongylium, possibly Strongylium erythrocephalum (no specific common name), subfamily Stenochiinae, family Tenebrionidae.
□ Among darkling beetles, this genus (Strongylium) is the largest in the world with as many as a thousand species. All have the rather cylindrical body seen here, and many have partially red legs.
□ This might be Strongylium erythrocephalum (no specific common name), which typically has a body length of around 2.5 cm (1 inch).
Photographed by: Amir Hamzah Othman. Identified by: KnowYourInsects.org. Location: Subang Jaya, Malaysia. Date: 20 November, 2021.

A darkling beetle in the genus Strongylium, possibly Strongylium erythrocephalum (no specific common name), subfamily Stenochiinae, family Tenebrionidae.
□ Many beetles, including darkling beetles, are identified in part by the number of segments in their tarsi, or their &ldquofeet” (not the claws). To determine this, look carefully at the tarsi and count the number of segments in the front, middle and hind legs. Darkling beetles have the pattern 5-5-4: five tarsal segments in front and middle legs; and four in the hind leg.
Photographed by: Jessy Phuah. Identified by: KnowYourInsects.org. Location: Kuala Lumpur, Malaysia. Date: 18 September, 2020.
Jessy says it was about an inch (2.5 cm) long.

Meloidae, the blister beetles

Margined Blister Beetle (Epicauta pestifera)

Margined blister beetle, Epicauta pestifer, subfamily Meloinae, family Meloidae.
□ The pronotum (the shield covering its thorax) and each elytra (the hardened forewings covering most of its back) of this margined blister beetle have light-colored outlines or margins. This beetle can do some damage to several garden plants, including potatoes and tomatoes.
Photographed by: Anonymous. Identified by: KnowYourInsects.org. Location: Adrian, Michigan, USA. Date: July, 2014.

A blister beetle in the genus Epicauta,, possibly the spotted blister beetle, Epicauta maculata, subfamily Meloinae, family Meloidae.
□ The spotted blister beetle is pale green, gray, or gray-beige with many small black polka dots. This is a tentative identification as several species in this genus (Epicauta) look very similar.
Photographed and identified to genus by: Tommy Vick. Identified to tentative species by: KnowYourInsects.org. Location: Fort Davis, Texas, USA. Date: 29 June, 2018.

Yellow-crescent blister beetle, Pyrota insulata , subfamily Meloinae, family Meloidae.
□ The yellow-crescent blister beetle often has thin slashes of orange toward the base of its two elytra (the hardened forewings covering most of its back) and a orange spot at the tip of each of its elytra. This one is a slightly different form with an orange-encircled spot at the base of each of its elytra, and no separated orange spot at the tip. To see the variety in this species, click here (a Texas Entomology website).
Photographed and identified by: Brenda Kirschner. Nice job on the ID, Brenda! Location: Stamford, Texas, USA. Date: 25 May, 2020.

Iron cross blister beetle, Tegrodera aloga, subfamily Meloinae, family Meloidae.
□ Female iron cross blister beetles lay their eggs in flower buds of a Palo Verde tree (in the genus Parkinsonia), and her tiny hatching larvae that then hitch a ride on a visiting bee, specifically one known as a digger bee (in the tribe Anthophorini). Once the larvae arrive at the bee’s nest, they disembark and eat the bees’ pollen and nectar, as well as the bees’ offspring. When the beetles become adults, they fly off to mate and start the cycle all over again.
Photographed by: Sandy Moody. Identified by: KnowYourInsects.org. Location: Mesa, Arizona, USA. Date: 12 May, 2021.

Orange Blister Beetle (Hycleus pustulata or Mylabris pustulata)

Orange blister beetle, Hycleus pustulata, subfamily Meloinae, family Meloidae.
□ The orange blister beetle — and other blister beetles in this family — actually do cause blistering if they are handled. Note: This species is sometimes listed as in the genus Mylabris.
Photographed by: Ajay Antony. Identified by: KnowYourInsects.org. Location: Tamilnadu, India. Date: 24 May, 2017.

Orange blister beetle, Hycleus pustulata, subfamily Meloinae, family Meloidae.
□ Notice the jaws and palps on this orange blister beetle. The palps are the small structures just below the jaws (they almost look like miniature antennae). The palps have sensory receptors on them, so they help the beetle to taste. Note: This species is sometimes listed in the genus Mylabris.
Photographed by: Shefali Chaudhari. Identified by: KnowYourInsects.org. Location: Gujarat, India. Date: 13 July, 2020.

Red-striped oil beetle, Berberomeloe majalis, subfamily Meloinae, family Meloidae.
□ The red-striped oil beetle usually has distinctive and bright red or orange bands on its abdomen. Not all red-striped oil beetles have the colored stripes: some are completely black. Regardless of the presence of stripes, this species secretes small drops of oil that can cause skin reactions in people, and illness if ingested. For more about this beetle, click here (Discover magazine).
Photographed and identified by: Paul Davis. Nice ID, Paul! Location: Monfrague National Park, Extremadura, Spain. Date: 9 May, 2019.

Bronze blister beetle, Lytta polita, subfamily Meloinae, family Meloidae.
□ This bronze blister beetle has beautiful, shiny-bronze elytra (the wings covering its abdomen); a purple-tinged head and pronotum (the shield covering the thorax); and black and reddish-orange legs. It is called a blister beetle because it will release some blood (called haemolymph) when it is agitated, and contact with the haemolymph can cause a reaction, such as non-painful, temporary blisters in on people’s skin.
Photographed by: Lisa Nolan. Identified by: KnowYourInsects.org. Location: northern Florida, USA. Date: 30 December, 2019.

Say’s blister beetle, Lytta sayi, subfamily Meloinae, family Meloidae.
□ Say’s blister beetles are sometimes seen munching on flowers, including irises (genus Iris), lupines (genus Lupinus) and lilacs (genus Syringa). Even with its somewhat ant-like head, it is quite a lovely beetle.
Photographed and identified to family by: Roger Olmstead. Nicely done, Roger! Identified to species by: KnowYourInsects.org. Location: Woodstock, New Brunswick, Canada. Date: 26 May, 2022.
Roger says, “It’s more than 1 inch (2.5 cm) in length.”

Say’s blister beetle, Lytta sayi, subfamily Meloinae, family Meloidae.
□ Say’s blister beetle looks almost identical to another species, except for the color of its elytra (the wings covering its back). Say’s blister beetle typically has black elytra, as seen above, while the nearly identical Lytta aenea has reddish-brown elytra. Lytta aenea is pictured elsewhere on this page.
Photographed by: Eric Besecker. Identified by: KnowYourInsects.org. Location: northern Vermont, USA. Date: 18 June, 2021.
Eric says he saw a different type of beetle in this family a couple of years earlier, but it was much larger.

Lytta aenea (no specific common name), subfamily Meloinae, family Meloidae.
□ Lytta aenea (no specific common name) has the species name aeneous, which means the color/luster of brass and refers to its elytra (the wings covering its back).
□ Its larvae latch onto certain types of bees for a free ride to the bees’ nests, where they feed on the bees’ eggs and larvae. To learn more about these and other fascinating blister beetles (Ohio State University).
Photographed and identified to genus by: John Hoagland. Nicely done, John! Identified to species by: KnowYourInsects.org. Location: Louisville, Kentucky, USA. Date: 12 April, 2021.
John says, “Found three this morning.”

Nuttall’s blister beetle, Lytta nuttalli, subfamily Meloinae, family Meloidae.
□ Nuttall’s blister beetle is a gorgeous beetle with a metallic head, thorax and abdomen; and purple elytra (the hardened forewings covering its back). And it is large — see the photographer’s comment below. This species eats rapeseed (Brassica napus), a yellow-flowered crop often grown in Canada to make into cooking oil.
□ During courtship, the male Nuttall’s blister beetle uses his antennae to stroke the tip of the female’s two antenna alternately, and then wiggles his abdomen back and forth such that long bristles on the rear underside of his abdomen brush against the tips of her elytra and the forward part of her upper abdomen. For a more detailed description, click here (The Canadian Entomologist journal). Photographed by: April Roch. Identified by:KnowYourInsects.org. Location: near Lloydminster in Alberta, Canada. Date: 28 June, 2019.
April says, “I saw this beautiful beetle in the early evening. It was about 2 inches long (5 cm) and that is not counting the antennae!”

A blister beetle in the Epicauta sericans group (no specific common name), subfamily Meloinae, family Meloidae.
□ Occasionally, entomologists lump a number of species into a “group.” The insects are all members of the same genus and very closely related, but are difficult to separate into distinct species. This blister beetle is in one such group: the Epicauta sericans group (or simply “sericans group”). The genus name of Epicauta is a combination of two Greek words that mean burning on the surface, and is a reference to the beetles ability to secrete a fluid that can cause an irritation to a person’s skin.
Photographed and identified by: Anne Guelker. Well done on the ID, Anne! Location: Shannon County, Missouri Ozarks, USA. Date: 24 July, 2022.
Anne spotted this beetle chewing on the leaves of the Baltic ivy around her home.

Oil beetles, mating pair, in the genus Meloe, possibly Meloe impressus (no specific common name), subfamily Meloinae, family Meloidae.
□ The photographer described the larger oil beetle (the female) as being approximately 1.5 inches (3.8 cm) long, and the smaller one (the male) at about 1.25 inches (3.2 cm) long. The size along suggests they may be the species Meloe impressus (no specific common name). See the photographer’s comment below.
Photographed and identified to genus by: Susan Anderson. Identified to tentative species by: KnowYourInsects.org. Location: Bethesda, Maryland, USA. Date: 25 November, 2018.
Susan found this pair in her garden. She says they “seemed green in sunlight.”

An oil beetle, possibly a short-winged blister beetle, Meloe angusticollis, subfamily Meloinae, family Meloidae.
□ With their black to blue-black color and ant-like heads, oil beetles are sometimes mistaken for ants.
Photographed by: Alexandra Scheumann, WoodHeaven Photography. Identified by: KnowYourInsects.org. Location: Hurleyville, Sullivan County, New York, USA. Date: 20 October, 2017.

Oil beetles get their name because they secrete an oil that contains cantharidin, also known as Spanish fly. To learn more, click here (McGill University).

□ A bird (a white-breasted nuthatch) makes use of the oil beetle’s repellant secretions by grasping the beetle in its bill and rubbing it on the outside of its nest, apparently to protect the nest from egg-nabbing squirrels. To read more about this observation, click here (The Auk journal, now named Ornithology).

An oil beetle, probably a black oil beetle, Meloe proscarabaeus, subfamily Meloinae, family Meloidae.
□ This bright blue-colored insect is tentatively identified as a black oil beetle by oil beetle experts Carolina Bravo and Mario García-París, but Dr. Bravo notes that only a good view of the mesonotum (the middle segment of the thorax) can rule out the almost identical violet oil beetle (Meloe violaceus).
Photographed and identified as an oil beetle by: Matthew Rodda. Identified to genus and tentative species by: Carolina Bravo of the National Museum of Natural History of Spain and Mario García-París of the Spanish National Research Council. Thank you, Drs. Bravo and García-París!
Location: Adjara, country of Georgia (between Western Asia and Eastern Europe). Date: 4 March, 2018.
Matthew found it in a rainforest.

An oil beetle in the genus Meloe, subfamily Meloinae, family Meloidae.
Photographed by: Chris G. Briggs, Sr. Identified by: KnowYourInsects.org. Location: northern Muskegon County, Michigan, USA. Date: 5 October, 2015.
Craig says, “A lone one was cutting through a grass blade with short, strong mandibles.”

An oil beetle in the genus Meloe, subfamily Meloinae, family Meloidae.
□ From this photo, it may look like this oil beetle’s hind legs sprout from the abdomen, but all six of its legs arise from its thorax (the narrow section behind the head). This is true of all adult insects: the legs and wings all attach to the thorax.
Photographed and identified by: Josh Bozarth. Well done on the ID, Josh! Location: Proud Lake Recreation Area, Wixom, Michigan, USA. Date: 31 October, 2018.

An oil beetle in the genus Meloe, subfamily Meloinae, family Meloidae.
□ When disturbed, oil beetles release fluid from their joints (as seen here). It is sometimes called “reflex bleeding.” The fluid is distasteful to potential predators, so it serves a protective function. Another feature of oil beetles is that the thorax is considerably narrower than the abdomen, and also narrower than the head.
Photographed by: Pat (no last name given). Identified by: KnowYourInsects.org. Location: Belding, Michigan, USA. Date: 7 October, 2014.

An oil beetle in the genus Meloe, subfamily Meloinae, family Meloidae.

Photographed and identified to order by: Victoria Meller. Identified to genus by: KnowYourInsects.org. Location: Kensington Metropark, Milford Township, Michigan, USA. Date: 27 September, 2020.

Flame-shouldered blister beetle, Sitaris muralis, subfamily Nemognathinae, family Meloidae.
□ The flame-shouldered blister beetle is found in small pockets in Europe, including infrequent sightings in the UK, where this one was photographed. This image shows its elytra (the hardened forewings covering its back) lifted to expose the all-black, membranous flight wings below.
Photographed by: Alexander Tonkinson. Submitted by: Jessamie Tonkinson. Identified by: Dave Hare and KnowYourInsects.org. Thank you, Dave! Location: Wiltshire, UK. Date: 11 August, 2017.
Jessamie says she saw this one buzzing around the back wall of her house in the garden. She notes that it had most of its wings exposed, and was roughly 12 mm (about 0.5 inches) in length. Her husband snapped the photo.

Oedemeridae, the false blister beetles

Swollen-Thighed Beetle (Oedemera nobilis)

Swollen-thighed beetles, also known as thick-legged flower beetles, Oedemera nobilis, subfamily Oedemerinae, family Oedemeridae.
□ These swollen-thighed beetles each have a lovely copper thorax and head. The male (left photo) has an enlarged femur (“thigh”) on each of its hind legs. The female (right photo) has slender legs.
Photographed and identified by: Jean-Louis Metzger. Well done on the ID, Jean-Louis! Location: Oxford, England, UK. Date: 27 May, 2019, for the female; and 29 May, 2019, for the male.

Swollen-thighed beetle, also known as a thick-legged flower beetle, Oedemera nobilis, male, subfamily Oedemerinae, family Oedemeridae.
□ The femurs on the hind legs of this male swollen-thighed beetle almost look like they have been inflated with a bicycle tire pump. The metallic green — a slightly different hue on the head and thorax — is quite eye-catching.
Photographed and identified by: Melanie Pritchard. Nice ID, Melanie! Location: Lousã, Portugal. Date: 15 May, 2020.

□ Swollen-thighed beetles are also sometimes called false oil beetles. The “oil” part of the name refers to the oil-like shine on their bodies.

Swollen-thighed beetle, also known as a thick-legged flower beetle, Oedemera nobilis, female, subfamily Oedemerinae, family Oedemeridae.
□ A feature of the swollen-thighed beetle is that its elytra (hardened forewings) do not entirely cover the abdomen, as shown in this photo. A similar-looking beetle is the lesser thick-legged flower beetle (Ischnomera cyanea), but it lacks the gap between the elytra.
Photographed by: Bryan Wenham-Baker. Identified by: KnowYourInsects.org. Location: Ivybridge, South Hams, South Devon, England, UK. Date: 1 August, 2018.

Swollen-thighed beetle, also known as a thick-legged flower beetle, Oedemera nobilis, female, subfamily Oedemerinae, family Oedemeridae.
□ The swollen-thighed beetle is a brilliant green. The closely related Oedemera lurida (no specific common name) also makes its home in the UK, where this photo was taken, but it is gray-green in color.
Photographed by: Bryan Wenham-Baker. Identified by: KnowYourInsects.org. Location: Ivybridge, South Hams, South Devon, England, UK. Date: 17 May, 2020.
Bryan notes that this species is sometimes known as false oil beetle.

Jean-Louis photographed this beautiful beetle in the garden.

Wharf borer, Nacerdes melanura, subfamily Oedemerinae, family Oedemeridae.
□ Wharf borer larvae bore long tunnels into decaying wood, often in wharfs, but anywhere they can find moist wood. The adults only live a week, and they usually emerge all at once.
Photographed and identified to order by: Mattias Lindstedt. Identified to species by: KnowYourInsects.org. Location: southern Spain. Date: 9 June, 2018.
Mattias says, “Length without antennas approx. 2 cm.” That’s a bit less than an inch long.

Mordellidae, the pintail beetles or tumbling flower beetles

A tumbling flower beetle in the genus Mordella, subfamily Mordellinae, family Mordellidae.
□ This is a close-up of one of a pair of tumbling flower beetles the photographer found on a Queen Anne’s lace plant(Daucus carota), also known as wild carrot. See identification information in the comment below.
Photographed by: Ed Hendrickson. Identified to genus by: entomologist Enrico Ruzzier of the Natural History Museum in London, UK. Location: North Carolina, USA. Date: 5 May, 2018.

Photographed by: Melanie Pritchard. Identified to family by: KnowYourInsects.org. Location: Lousã, Portugal. Date: 15 May, 2020.

Zopheridae, the ironclad beetles and the cylindrical bark beetles

Southwestern ironclad beetle, Zopherus nodulosus, subfamily Zopherinae, family Zopheridae.
□ If they are touched or feel threatened, southwestern ironclad beetles will draw in their legs and play dead. They are quite impressive beetles in color and size, and can reach about 2 inches (5 cm) long.
Photographed by: Cedia Miller. Identified by: KnowYourInsects.org. Location: Unknown. Date: 2 May, 2016.

□ Another groups of insects has a beetle with the common name of desert ironclad beetle (Asbolus verrucosus), but it is no relation to the Zopheridae family, and is actually one of the darkling beetles in the family Tenebrionidae, and is pictured on this page here.

Coccinellidae, the ladybugs or ladybird beetles

Yellow-crested aegis, Egius platycephalus, subfamily Chilocorinae, family Coccinellidae.
□ The yellow-crested aegis is distinguished by its flat-black coloration with a contrasting yellow pronotum. It eats pest-damaging aphids and scale insects.
□ The yellow-crested aegis is an introduced species in Florida (where this one was photographed), first recorded in that state in 2013. To learn more about this little beauty (only about 4mm or 0.17 inches long), click here (University of Florida “Featured Creatures” website).
Photographed and identified to family by: Heather Collazo. Identified to species by: KnowYourInsects.org. Location: West Palm Beach, Florida, USA. Date: 5 March, 2020.
Heather says, “This is the second I have seen in the past three months.”

Exochomus childreni (no specific common name), subfamily Chilocorinae, family Coccinellidae.
□ This species of ladybug has no official common name of its own, so the photographer proposed “minilady” because it was “small enough to be on an aphid’s dinner plate” (see his comment below).
□ It has a black head and thorax, and dark orange to brown elytra (the hardened forewings covering its back) with black blotches on the ends and often black blotches toward the front of its elytra.
Photographed and identified to family by: Marv Goldberg. Identified to species by: KnowYourInsects.org. Location: Tamarac, Florida, USA. Date: 25 May, 2020.
Marv says, “This huge beast was about 1/8 inch (3 mm). I wasn’t even sure it was an insect, so I had to photograph it.”

Pine ladybird beetle, Exochomus quadripustulatus, subfamily Chilocorinae, family Coccinellidae.
□ The two large red spots on this pine ladybird beetle have a distinctive comma-like shape. It also has a pair of smaller red spots behind the two large ones. As its name suggests, it is frequently found in pine forests.
Photographed and identified by: Eric Blehaut. Nicely done on the ID, Eric! Location: Lille, France. Date: 7 June, 2023.

Cactus ladybug, sometimes called a cactus lady beetle, pupa, Chilocorus cacti, subfamily Chilocorinae, family Coccinellidae.
□ Once this pupa of a cactus ladybug is ready to become an adult, the back will split open and the adult will emerge. To see an adult emerging from the pupa, click here (BugGuide).
□ To see the adult, which is black with two large red spots, click here (BugGuide).
Photographed by: Jack Slatter. Identified by: KnowYourInsects.org. Location: Emory, Texas, USA. Date: 8 August, 2020.
Jack spotted this pupa while repairing the eave on his house.

Heather ladybird beetle, Chilocorus bipustulatus, subfamily Chilocorinae, family Coccinellidae.
□ The heather ladybird beetle is dark brown or purplish brown (sometimes appearing black) with two red spots on its elytra (the hardened forewings covering its back). Some individuals may have three red spots instead, or spots that bleed into one another to appear as a rectangular blotch. It is used to contol pest scale insects (see comment below).
Photographed by: Mohammed Al-Tawayah. Identified by: KnowYourInsects.org. Location: north of Jordan. Date: April 2021.
Mohammed says he found this beetle in cactus plants infested with cochineal scale insects. To learn more about cochineal scale insects, click here (University of California website).

Seven-Spot Ladybird Beetle (Coccinella septempunctata)

Seven-spot ladybird beetle/ladybug, larva, Coccinella septempunctata, subfamily Coccinellinae, family Coccinellidae.
□ The larva of the seven-spot ladybug can be distinguished from other ladybug larvae by the red markings on its abdomen. It has no red markings past the fourth abdominal segment (numbered abdominal segments are noted as A1, A2, A3, etc.; the three segments of the thorax are labeled as T1, T2 and T3).
□ The seven-spot ladybug has such a hunger for aphids that it has been introduced multiple times in the United States (where this photo was taken) to control them .
Photographed by: Thomas Langhans. See Thomas’s original, full-size image here. Location: San Bruno, county of San Mateo, California, USA. Date: 12 March, 2018.

Seven-spot ladybird beetle/ladybug, larva Coccinella septempunctata, subfamily Coccinellinae, family Coccinellidae.
□ The seven-spot ladybird beetle does indeed have seven spots: three smaller spots on each of the elytra (the two hardened forewings covering its back) and one larger one that spreads onto the front of both elytra (between the two white spots). This is quite a common species in Europe.
Photographed and identified by: Bryan Wenham-Baker. Well done, Bryan! Location: Ivybridge, South Hams, South Devon, England, UK. Date: unknown.

Seven-spot ladybird beetle/ladybug, Coccinella septempunctata, subfamily Coccinellinae, family Coccinellidae.
□ This head-on view of the seven-spot ladybug (called a ladybird beetle in the UK) shows the pair of small white dots on its head, the larger white spots on either side of its pronotum (the shield that covers the thorax), and the pair of white spots just behind the pronotum.
Photographed by: Thomas Langhans. See Thomas’s full-size image here Location: San Bruno, county of San Mateo, California, USA. Date: 4 November, 2018.

Seven-spot ladybird beetle/ladybug, larva, Coccinella septempunctata, subfamily Coccinellinae, family Coccinellidae.
□ Gardeners like seven-spot ladybug larvae because they prey on plant-damaging aphids. A close look at this photo will reveal an aphid crawling on this larva’s back, and more in the lower right corner.
Photographed by: Thomas Langhans. See Thomas’s full-size image here. Location: San Bruno, county of San Mateo, California, USA. Date: 12 March, 2018.

Seven-spot ladybird beetle/ladybug, larva Coccinella septempunctata, subfamily Coccinellinae, family Coccinellidae.

Three-banded ladybug (Coccinella trifasciata perplexa)

Three-banded ladybug/ladybird beetle, Coccinella trifasciata perplexa, subfamily Coccinellinae, family Coccinellidae.
□ There are two subspecies of three-banded ladybugs in the U.S. This is Coccinella trifasciata perplexa, which was photographed in Michigan; the other (Coccinella trifasciata subversa) lives along the Pacific coast of the U.S. and southern Canada, and is pictured elsewhere on this page. Coccinella trifasciata perplexa (as shown above) has three (often broken) black bands across its elytra.
□ This one has a yellow background color, but in other individuals, the background color is orange instead.
Photographed and identified by: Leslie Mertz. Location: Houghton Lake, Roscommon County, Michigan, USA. Date: 7 July, 2017.
Leslie says, “Such a pretty little ladybug!”

Three-banded ladybug (Coccinella trifasciata subversa)

Three-banded ladybug/ladybird beetle, Coccinella trifasciata subversa, subfamily Coccinellinae, family Coccinellidae.
□ This subspecies of three-banded ladybug (Coccinella trifasciata subversa) lives along the west coast of the U.S. and southern Canada. It has no more than one wide black band (and sometimes none) across its elytra. This compares to the other subspecies (Coccinella trifasciata perplexa), which has three black bands, as described elsewhere on this page.
□ The similar-looking transverse ladybug (Coccinella transversoguttata) has a slightly different pattern on its pronotum (the shield covering the thorax). To see the transverse ladybug, click here (BugGuide).
Photographed by: Thomas Langhans. See his full-size photos here and here. Location: city of San Bruno, county of San Mateo, California. Date: 20 February, 2023.
Thomas says, “First thing I noticed about it was how small it was compared to other lady beetles I see around here, at least half the size.”

California Ladybird Beetle (Coccinella californica)

California ladybird beetle/ladybug, larva, Coccinella californica, subfamily Coccinellinae, family Coccinellidae.
□ Compared to all the spotted species of ladybugs, this California ladybird beetle has an understated sophistication with its single black stripe down the middle. Compare it to the spotless ladybug (Cycloneda sanguinea) pictured elsewhere on this page.
□ It lives near the coast from California up into Oregon and Washington, and even a short distance into British Columbia.
Photographed and identified to family by: Thomas Langhans. See Thomas’s full-size images here and here. Location: San Bruno, county of San Mateo, California, USA. Date: 26 March, 2022.
Thomas (who moved to California a while back) says this photo of a California ladybird in his yard “might prove that I actually live in California; that I am not just ‘California Dreamin’ like I used to do so many years ago!” This beetle was Thomas’s first introduction to the species :-)

Subvittate ladybug, Myzia subvittata, subfamily Coccinellinae, family Coccinellidae.
□ Some subvittate ladybugs tend to be more yellow (like this one) while others are more orange, and the amount of black streaking also varies quite a bit. They all, however, have two white blotches on the pronotum (the shield covering the thorax), and most have the two, small, white smeary spots just behind the pronotum (as seen in the photo above).
Photographed by: Carole Martens. Identified by: KnowYourInsects.org. Location: Whistler, British Columbia, Canada. Date: 28 July, 2020.

Orange ladybird beetle, Halyzia sedecimguttata, subfamily Coccinellinae, family Coccinellidae.
□ Orange ladybird beetles were once quite rare in the UK, but are now becoming more common.
Photographed and identified by: Yvonne Ugarte. Well done, Yvonne! Location: Leeds, West Yorkshire, UK. Date: 17 October, 2016.
Yvonne says, “I do not see these very often. It has been very mild so far though (this fall).”

14-spot ladybird beetle, Propylea quatuordecimpunctata, subfamily Coccinellinae, family Coccinellidae.
□ This 14-spot ladybird beetle is sometimes called a chessboard ladybug, and with this individual’s pattern, it is easy to see why.
□ This species zips through its development. It can take less than two weeks for it to go from egg to larva to pupa to adult. To read more about this beetle, click here (UK Beetles).
Photographed and identified by: Diana Luntena. Nicely done, Diana! Location: Riga, Latvia. Date: 10 August, 2023.

14-spot ladybird beetle, Propylea quatuordecimpunctata, subfamily Coccinellinae, family Coccinellidae.

Photographed and identified to family by: Bryan Wenham-Baker. Location: Ivybridge, South Hams, South Devon, England, UK. Date: 11 May, 2019.

Sulfurous lady beetle, Cheilomenes sulphurea, subfamily Coccinellinae, family Coccinellidae.
□ The sulfurous lady beetle<.b> is black with either yellow or creamy-white spots, and a smear of pink or red on the side spots. The amount of the smear varies between individuals.
Photographed and identified to family by: Sarah Park. Identified to species by: KnowYourInsects.org. Location: Central African Republic. Date: 19 February, 2024.

The word sanguinea — or variations of it — come up now and then in scientific names of insects. It refers to a blood-red color, and comes from the Latin word sanguis, which means blood.

Spotless Lady Beetle (Cycloneda sanguinea)

Spotless ladybug, Cycloneda sanguinea, subfamily Coccinellinae, family Coccinellidae.
□ Not surprisingly, the spotless ladybug lacks spots on the elytra (the hardened forewings covering its back). Because of the red-orange color of the elytra (the forewings covering her abdomen), spotless ladybugs are sometimes called blood-red ladybugs.
Photographed by: Marv Goldberg. Identified by: KnowYourInsects.org. Location: Tamarac, Florida, USA. Date: 5 April, 2019.
Marv says, “I don’t believe I ever saw a no-spotted ladybug before (I swear, I didn’t paint it).”

Spotless ladybug, Cycloneda sanguinea, female, subfamily Coccinellinae, family Coccinellidae.
□ This is a female spotless ladybug, and she can be distinguished from the male by the pattern on the pronotum (the shield between the head and the orange-red wings). In the male, the white outline continues all the way around the front of the pronotum and he also has a white line partially down the center of the pronotum. To see the male, click here (BugGuide). In the female, the white outline is broken and she has no central white line — the left photo shows that perfectly!
Photographed and identified by: Thomas Langhans. Nicely done, Thomas! See Thomas’s full-size images here and here. Location: city of San Bruno, county of San Mateo, California, USA. Date: 27 August, 2022.

20-Spotted Lady Beetle (Psyllobora vigintimaculata)

20-spotted lady bug, Psyllobora vigintimaculata, subfamily Coccinellinae, family Coccinellidae.
□ The design on this 20-spotted lady bug has a splotchy pattern of brown and slightly lighter brown on its elytra (the hardened forewings covering its back). This design is only seen among individuals in California (where this photo was taken). Outside California, individuals in this species have separate brown or black spots, and the white background occasionally has a pale-orange tint.
Photographed by: Thomas Langhans. See full-size photos (clockwise from upper left) here, here, and here. Identified by: KnowYourInsects.org. Location: San Bruno, county of San Mateo, California. Date: 4 July, 2021.

Damian says, “This guy is itty bitty, it’s around 5 mm (?). That was taken on my very old formica counter.” KnowYourInsects.org replies, “Nice estimation on size, Damian! This beetle is indeed tiny, growing to about 3 mm long.”

15-spotted ladybug/ladybird beetle), Anatis labiculata, subfamily Coccinellinae, family Coccinellidae.
□ This is the typical color and pattern of the 15-spotted ladybug: 15 black spots on a light-gray (sometimes orangish) background with the orange line down the middle of the back. Other entries on this page show how the coloration darkens with age.
Photographed by: Denise Rulason. Identified by: KnowYourInsects.org. Location: Interlochen, Michigan, USA. Date: 23 June, 2018.

15-spotted ladybug/ladybird beetle), Anatis labiculata, subfamily Coccinellinae, family Coccinellidae.
□ Typically, the 15-spotted ladybug indeed has 15 black spots on a light-gray to orange background. As they age, however, they sometimes become quite dark, like this one, although the black spots are still visible.

□ This is another older 15-spotted ladybug with even darker coloration than the previous photo.
Photographed and identified by: Leslie Mertz. Location: Houghton Lake, Roscommon County, Michigan, USA. Date: 7 July, 2017.
Leslie says, “I met a woman who told me she was seeing ticks all over the place, and it turned out to be these brownish-black ladybugs!”

Many myths surround ladybugs. One of KnowYourInsects.org’s favorites is that ladybugs can make wishes come true: Just hold a ladybug in the hand, make a wish, and watch it fly off. The granted wish will come from whatever direction the ladybug flew.

Eye-spotted ladybug, Anatis mali, subfamily Coccinellinae, family Coccinellidae.
□ This eye-spotted ladybug has lots of white-encircled eye spots. Some individuals are more orange or more brown, and some have black spots with only minimal or no white outlining.
Photographed by: Eda Walter. Identified by: KnowYourInsects.org. Location: Alberta, Canada. Date: 30 May, 2022.

Eye-spotted ladybug, pupa, Anatis mali, subfamily Coccinellinae, family Coccinellidae.
□ Beetles go through four phases: egg, larva, pupa, adult. This is the pupa, likely of an eye-spotted ladybug. As seen in the left photo, the pupa will often attach one end to a surface, usually a leaf or stem, but in this case man-made material.

Six-Spotted Zigzag Ladybird Beetle (Cheilomenus sexmaculata)

Six-spotted zigzag ladybird beetle, or zigzag beetle, Cheilomenus sexmaculata, subfamily Coccinellinae, family Coccinellidae.
□ Six markings with four in a zigzag pattern are the hallmark of the aptly named six-spotted zigzag ladybird beetle. In some cases, the background color is cream (as seen here), and in others, it is orange. Like many different ladybird beetle/ladybug species, six-spotted zigzag ladybird beetles have aphids on the menu, and are being studied as a potential biocontrol agent (PLoS journal).
