Immature Stages of Trichoptera
Detailed information on immature stages of Trichoptera is being acquired. However, Clausen (1940) noted that all caddis fly larvae are aquatic and feed mainly on decaying vegetation, though some species are predaceous. Eggs are laid in masses on stones, plants or other objects in the water or upon objects above the water surface. The larvae are eruciform and build about themselves silken cases or tubes that are overlaid with particles of sand, small pebbles, etc.
