Although the mealybug destroyer is widely advert- ised, supplies are often limited due to difficulties in maintaining colonies. The Green Lacewings, Chrysoperla (formerly Chrysopa) carnea and Chrysoperla rufilabris Green lacewings occur naturally throughout North America and are widely available for pur- chase and release. Adult green lacewings have delicate, light green bodies, large, clear wings, and bright golden or copper-colored eyes. The larvae are small, greyish brown, and elongate and have pincerlike mandibles. Green lacewing eggs are found on plant stems and foliage. They are laid singly or in small groups on top of fine, silken stalks which reduce predation and parasitism by keeping the eggs out of reach (Figure 5). Green lacewing larvae are generalist predators of soft-bodied insects, mites, and insect eggs, but they feed primarily on aphids and are commonly known as "aphid ; Lacewing larvae are also cannibal- istic, feeding readily on other lacewing eggs and larvae if prey populations are low. Larvae feed for about 3 weeks before pupating inside silken cocoons that are usually attached to the undersides of leaves. Although adults of some lacewing species are predaceous, Chrysoperla carnea adults feed only on nectar, pollen, and aphid honeydew. Chrysoperla carnea females cannot produce eggs if these foods are not available. Green lacewing adults make long dispersal flights soon after emerging from the pupal stage; this dispersal takes place regardless of whether or not ample food is present when the.
