Lacewings

Neuroptera: Chrysopidae, Hemerobiidae


The adult is green (Chrysopidae), or light brown (Hemerobiidae) with large translucent membranous wings (A) that are held roof-like over the body. Brown lacewings are typically half the size of green lacewings. The larva has a tapered abdomen and large mandibles (B). Chrysopid eggs (1 mm) are whitish green and are deposited, singly or grouped, on long thread-like stalks (C) (10 mm); those of hemerobiids are laid singly on plant surfaces without a stalk. Note: Lacewings are sensitive to most broad-spectrum insecticides.
