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 (some up to 18 mm). These insects differ from the somewhat similar Chrysopidae (green lacewings) not only by the usual coloring but also by the wing venation: hemerobiids differ from chrysopids in having numerous long veins (two or more radial sectors) and forked costal cross veins. Some genera (Hemerobius, Micromus, Notiobiella, Sympherobius, Wesmaelius) are widespread, but most are restricted to a single biogeographical realm. Some species have reduced wings to the degree that they are flightless.[1] Imagines (adults) of subfamily Drepanepteryginae mimic dead leaves. Hemerobiid larvae are usually less hairy than chrysopid larvae.
Hemerobiids, like chrysopids, are predatory, especially on aphids, both as larvae and adults. The species Micromus tasmaniae is bred for biological pest control.[2]
