Most Leptoceridae antennae are longer than those of other caddisflies. Leptoceridae larvae have dense swimming hairs and long hindlegs that protrude outside of their case, which enable them to be effective swimmers. Swimming allows the larvae to quickly move among aquatic vegetation in search of food or shelter.
Leptocerid larvae exhibit a wide range of water quality tolerances and feed on a wide variety of foods, ranging from detritus and algal grazing to predation of freshwater sponges. Feeding guilds include scrapers, shredders, and predators. They occupy ponds, marshes, lakes, and the slower currents of streams, especially where aquatic plants are found. Specific habitat, water quality, and dietary requirements differ between species.
