The Case-building Caddisfly builds a portable case from twigs, sand grains, and plant debris cemented with silk — each species' case has a characteristic architecture used in identification. Larvae drag their cases as they crawl over stream and pond bottoms. Adults resemble small moths, are nocturnal, and are classic fly-fishing models. They play a major role in stream ecosystem nutrient cycling.
