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.
Did You Know?
Entire rock surfaces can be covered in a patchwork of silken tubes built by dense colonies.
Saddle-Case Caddisfly
A small caddisfly whose larvae build distinctive saddle-shaped cases from tiny stones. When it pupates, it cuts the case free from the rock and seals itself inside.
Did You Know?
Saddle-case caddisfly larvae graze algae so efficiently that they can create visible clean patches on otherwise algae-covered stream rocks.
