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.
Green Sedge
A free-living caddisfly larva that does not build a case, instead roaming the streambed as an active predator. Adults have greenish wings.
Did You Know?
Unlike most caddisflies, green sedge larvae are caseless predators that hunt like underwater wolves among the stream cobbles.
