Limnephiloid Snail Caddis
A tiny caddisfly that builds a perfectly spiraled case from fine sand grains cemented with silk. Larvae scrape algae from rock surfaces in clear streams.
Did You Know?
The coiled case provides structural strength far exceeding that of a simple tube of the same material.
European Glowworm
A well-known European firefly where only the wingless female produces a steady green glow. Males are winged but produce no light.
Did You Know?
Females glow for up to two hours each night to attract flying males, then stop after mating.
