Larva & Pupa Biology
The larvae very much resemble pennies from one side. Their whole bodies are an excellent suction cups, their legs are strong for clinging to rocks, and they are somewhat translucent and extremely well-camouflaged. The result is an extremely well-adapted fast-water insect which probably rarely if ever ends up in the drift for the trout.3 Beetle Specimens in the Family Psephenidae:
