Order Trichoptera


The caddisflies are medium-sized, four-winged, moth-like insects having long, slender antennae. They have chewing mouthparts, but the adults probably do not feed. Metamorphosis is complete, the life stages being the egg, larva, pupa, and adult. The larvae of caddisflies live in streams and ponds and cover their bodies with portable cases made of small stones and other materials webbed together with silk. This case-making habit gives the order its common name, since the word caddis means "case". The adults are found near the streams, ponds, or lakes in which the larvae live. Caddisflies are attracted to lights in large numbers.
