Little Black Caddis
A small, dark caddisfly that builds finger-shaped silk nets in stream crevices. It is widespread in warm-water streams across eastern North America.
Did You Know?
Its silk capture tube is among the finest-meshed nets of any caddisfly, trapping microscopic food particles.
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.
