Larvae of the hydropsychids construct nets at the open ends of their dwellings which are responsible for their "net-spinning caddisfly" common name. Net or sieve made of fine silk, similar to the silk produced by the larval form of the Lepidoptera (caterpillars), one of their close relatives. These nets catch algae, detritus, and smaller invertebrates. Different genera spin nets of different mesh sizes and shapes depending on what food type they are targeting. Because of this technique of food collection, most hydropsychids require flowing water to ensnare items of food into their nets.
Suborder: Annulipalpia Superfamily: Hydropsychoidea
