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.


Larvae and adults of many species are predators of mites and soft-bodied insects.

Note: Natural control of aphids is possible when there is one larva per 70 aphids.
