1962 Hylaea fasciata (Barred Red)

Geometridae, Ennominae Wingspan: 34-42mm.

Another common species throughout the UK, and widespread but not quite as common in Cornwall. The smooth red cross-bar outline on the forewings serve to separate it from the similar 1903 Barred Umber. Contrary to the common name, some males of this species can appear in a dull green form (H.f.prasinaria), although this is rare in the UK and more common in Europe.

The flight season in the UK is defined as mid June to early August, but occasional individuals in May and October have been recorded in Cornwall.
