Sand-Case Caddisfly
A caddisfly whose larvae build smooth, curved cases entirely from fine sand grains cemented with silk. Adults are dark with hairy wings.
Did You Know?
The curved sand-grain cases built by these larvae are so precisely constructed they resemble tiny miniature architectural works.
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.
