Hemerobiidae is a family of Neuropteran insects commonly known as brown lacewings, comprising about 500 species in 28 genera. Most are yellow to dark brown, but some species are green. They are small; most have forewings 4–10 mm long. These insects differ from the somewhat similar Chrysopidae not only by the usual coloring but also by the wing venation: hemerobiids differ from chrysopids in having numerous long veins and forked costal cross veins. Some genera are widespread, but most are restricted to a single biogeographical realm. Some species have reduced wings to the degree that they are flightless. Imagines (adults) of subfamily Drepanepteryginae mimic dead leaves. Hemerobiid larvae are usually less hairy than chrysopid larvae.
