Glacial Stonefly
A small, slender stonefly found in the coldest alpine headwater streams. Its needle-like wings are rolled tightly around its body at rest.
Did You Know?
Its rolled-wing resting posture gives the family its common name of needle flies.
Western Bushtail Caddisfly
A western North American caddisfly that constructs smooth cylindrical cases from fine sand. Larvae are leaf-shredders in forested streams.
Did You Know?
Larvae migrate upstream as they grow, compensating for the downstream drift they experienced as young instars.
