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.
