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.

Mothlike Caddisfly

An elegant caddisfly with pale straw-colored wings and long antennae found near still waters. Larvae build slender spiral cases from plant fragments and swim actively.

💡

Did You Know?

Triaenodes larvae are unusual among caddisflies in being strong swimmers, propelled by their fringed hind legs.
