Sialidae (alderflies; subclass Pterygota, order Megaloptera) Family of insects which are similar to the Corydalidae, but are usually much smaller and lack ocelli. They are blackish-grey, resemble lacewings, and are found near ponds or streams, where their larvae develop. The larvae are similar to those of the Corydalidae, but lack hooked, anal prolegs, and have a terminal filament.
