Family Psephenidae - Water Penny Beetles

The Psephenidae are best known by their trilobite-like larvae, which are common beneath stones in fast-flowing streams and rivers. The water pennies feed on algae while clinging tightly to the substrate. The adults linger about on rocks or emergent vegetation.
