Tube-Making Caddis
A small caddisfly whose larvae build silken tubes cemented to rock surfaces in rivers. The tubes create a network of galleries on submerged stones.

Entire rock surfaces can be covered in a patchwork of silken tubes built by dense colonies.

A small riffle beetle with elongated tarsal claws for gripping rocks in fast currents. Both adults and larvae are entirely aquatic.

Adults can live for several years underwater, far longer than most beetles.
