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.
Sand-Dwelling Caddis
A caddisfly whose larvae build flattened shield-shaped cases from sand grains. The wide case acts like a snowshoe, preventing the larva from sinking in soft sediment.
Did You Know?
Its case has lateral flanges that distribute weight and prevent sinking into soft sand.
