Sand Fly Caddis
A small caddisfly whose larvae build distinctive tortoise-shell-shaped stone cases. They are important grazers on algae-covered stream rocks.
Did You Know?
Glossosoma larvae abandon and rebuild their dome-shaped cases each time they need to move to a new grazing site.
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.
