About Green Lacewings (Chrysoperla rufilabris):

The Green Lacewing is a nocturnal predator that aggressively and lethally consumes aphids and other soft bodied insects. The Green Lacewings life cycle is made up of three stages; eggs, larvae and adult stages. When the female Green Lacewing lays her eggs, they tend to pick an area with sufficient plants and leaves. The eggs are attached to a hair-like thread until the egg hatches. The larvae of the Green Lacewings are very ferocious in hunting down soft bodied insects. The larvae can grow up to 3/8th of an inch and they seize their prey and inject them with paralyzing venom. The Green Lacewing Adults feed on pollen and nectar however lay a lot of eggs. Adults are useful for the release onto trees, for as adults they have wings to fly. Green Lacewings also attack the eggs of pests. Green Lacewings will also attack most soft-bodied pests such as:  Aphids, Thrips, Spider Mites, greenhouse whiteflies, mealy bugs, leafhoppers, and the eggs and caterpillars of most pest moths. Of all available commercial predators, this lacewing is the most ferocious and it adapts easily to go after pests of field crops, orchards, and greenhouses.

Lifespan of Green Lacewings:

Each lacewing larva will devour 200 or more pests or pest eggs a week during their two to three week developmental period. After the larvae stage the Green Lacewing Larvae wraps itself in a cocoon silken thread. Approximately five days later adult Lacewings emerge to mate and repeat the life cycle. Depending on the weather conditions, the adult will live for roughly four to six weeks.
