Larva & Pupa Biology

Gary LaFontaine describes the unusual shelters built by these larvae in Caddisflies:

The larva builds a retreat, or dwelling tube, by raising a simple roof or a groove in a sunken piece of wood. The tube is camouflaged with pieces of detritus (Detritus: Small, loose pieces of decaying organic matter underwater.) and a layer of silk.

Larvae: Many classes of aquatic insects, such as caddisflies, midges, craneflies, dobsonflies, alderflies, and many more, are known as "larvae" rather than "nymphs" in their juvenile stages. They have mostly soft bodies rather than hard exoskeletons. These insects also advance through a "pupa" stage before reaching adulthood.
