Green lacewings are predators found in most environments. Several species of Chrysoperla and Chrysopa are important predators. The light green adult has long, slender antennae, golden eyes, and large, veined, gauze-like wings that are 1/2 - 1/3 inches long. It is a slow-flying, nocturnal insect that feeds on nectar and pollen, and it emits a foul-smelling fluid from special glands if captured. The female lacewing lays eggs usually in groups on leaves, each egg held away from the leaf surface on the end of a slender stalk. A female lays up to 300 eggs over a period of 3-4 weeks, but often it does not survive that long in the field. The green lacewing larvae are voracious feeders and can consume up to 200 aphids or other prey per week. In addition to aphids, they will eat mites and a wide variety of soft-bodied insects, including insect eggs, thrips, mealybugs, immature whiteflies, and small caterpillars. They will also consume each other if no other prey is available.
