Because Green Lacewing larvae eat aphids, ants are quick to kill them to protect the herd, hence the need for camouflage. If left undisturbed by ants, Green Lacewings can control aphid populations without the need for chemical pesticides. Mature Lacewings are most active in the summer months.
Lacewing eggs hatch in about 3-5 days after reaching temperature of about 60 °F. Larvae are predators for 2 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.
