Hemerobiidae

"Hemerobioidea" redirects here. Numerous lacewing families were formerly included there but now are placed elsewhere; see text for details.

Hemerobiidae is a family of Neuropteran insects commonly known as brown lacewings. These insects differ from the somewhat similar Chrysopidae (green lacewings) not only by the usual colouring but by the wing venation: hemerobiids having numerous long veins lacking in chrysopids. Some of the costal cross veins are forked, unlike in green lacewings. Imagines of subfamily Drepanepteryginae mimic dead leaves. Hemerobiid larvae are usually less hairy than chrysopid larvae.
