Additional Information
Life History
Adult green lacewings primarily feed on nectar but can also consumer small insects. Green lacewings lay eggs on a stalk to prevent newly hatched larvae from cannibalizing each other. These eggs are distinct and unique to lacewings. Lacewing larvae are voracious predators capable of feeding on small caterpillars and beetles, as well as aphids and other soft-bodied insects. Immature lacewings look superficially like lady beetle larvae but are light brown with a large pair of forward-facing, sickle-shaped mandibles. Lacewings are commercially available for purchase and can provide effective biological control of pests particularly in small-scale production systems and greenhouses.
