Mother-of-Pearl Caddis
A large European caddisfly with translucent wings that shimmer with iridescence. Larvae construct flat cases from pieces of dead leaves.

Larvae cut leaf pieces into precise rectangles to build their distinctive flat cases.
Grannom Caddisfly

Grannom hatches are so dense on some rivers that local people historically swept up mounds of dead adults to use as fertilizer.
