Adult caddisflies are commonly 3 to 15 millimetres (0.118 to 0.590 inch) in length. Their anterior wings usually range from 4 to 20 millimetres in length, providing wing spans of 8 to 40 millimetres. The wings at rest are folded rooflike and cover the top of the body.

This flight period lasts anywhere from a few days to a few months, depending on the species, so mating adults may be seen on or over the water long after emergence is complete.

A complete overview of the lifecycle of a caddisfly from larva, pupa, pharate adult, winged adult to the mating and egg laying
