BIOLOGY

Adults and larvae are predatory on small Homopterans, (predominantly Aphididae) and may sometimes be important in limiting pest populations. They are very commonly encountered on vegetation.
Lacewing larvae affectionately called "aphid lions" feed on a large number of soft bodied pests, mites and insect eggs. A voracious predator they can consume as many as 60 aphids an hour. Shipped as eggs in vermiculite, lacewing larvae will feed for 2-3 weeks before becoming adults. Habitat: Green lacewings are very common insects, found on grass, weeds, and shrubs, usually in relatively open areas. They often give off an unpleasant odor when handled. Larvae sometimes fall from trees or shrubs and may pierce the skin causing minor irritation. Adults and larvae feed principally on aphids and are important agents in the control of these insects. Eggs are laid at ends of tiny stalks, usually on foliage; the larvae, which have long sickle-shaped mandibles, pupate in small pea-shaped silken cocoons.
