Description: Green Lacewings are general predators that feast on a variety of insects. They are very effective on aphids. During the larval stages it is a predator. Adults are large green insects with large, almost transparent green lace-like wings. Larvae are small, alligator looking critters with noticable legs. They move from plant to plant on leaves. Larvae pupate on upper leaf surfaces, plant stems and twigs. Eggs are laid on hair-like filiments — up to 600 eggs per adult. Storing the eggs can be done at a temperature of 40 degrees fahrenheit for 1-3 weeks. Ideally, Green Lacewings should be released as soon as you see larvae hatching out. Each packet of Lacewings has dispersement packages provided, each pouch should be placed in the crotch of the plant limbs or stapled /paper clipped to leaves. Once pouches are placed, pour a small amount of material in each pouch. Spread the release sites out as much as possible. To improve performance, ants must be controlled. Several generations may occur during one season.
Lifespan: Egg to adult, about 30 days depending on weather. Adults live for 10-40 days and will lay 10-30 eggs per day and up to 600 eggs on hair-like filaments. Lacewing weggs hatch in about 3-5 days after reaching a temperature of about 60 degrees. Larvae are predators for two weeks or longer if nights are cool. During 2-3 larval stages, one solitary Lacewing can kill 300-400 aphids, 11,000 spider mites, 3,700 scale crawlers or 6,000 scale eggs,. Cocoons yield adult Lacewings in about 5 days. The adult Lacewing will migrate towards pollen, insect honeydew or nectar before laying eggs. Temperature and food availability will determine the timing of each stage and reproductivity.
Strategic Considerations: Pestisides and even-wetting agents and spreader-stickers may adversely affect Lacewing survival. Broad spectrum and systemtic insecticides are toxic to Lacewings.
