Mother-of-Pearl Caddis
A large European caddisfly with translucent wings that shimmer with iridescence. Larvae construct flat cases from pieces of dead leaves.
Did You Know?
Larvae cut leaf pieces into precise rectangles to build their distinctive flat cases.
Crawling Water Beetle
A tiny, oval water beetle with a yellowish body covered in rows of dark punctures. Unlike diving beetles, it crawls slowly among aquatic vegetation rather than swimming actively.
Did You Know?
It stores air beneath enlarged hind coxal plates, which act as a built-in oxygen reservoir while submerged.
