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.
Little Olive Sedge
A common North American net-spinning caddisfly tolerant of a range of water qualities. Larvae build intricate filtering nets in crevices between cobbles.
Did You Know?
Silk nets are species-specific in mesh size, tuned to the preferred food particle diameter.
