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.
Great Grey Sedge
One of the largest net-spinning caddisflies in North America with a wingspan over 40 mm. Larvae build robust catch-nets in powerful mountain torrents.
Did You Know?
Larvae are partially predatory, consuming small invertebrates trapped in their nets alongside organic debris.
