Lacewings are pale
green insects about one inch long and have shiny golden eyes. Their wings
have many veins, which gives them the netlike or "lace" appearance. When
in flight they may resemble delicate moths. Lacewings lay their pale green
eggs on the tips of threadlike stalks on the underside of leaves. The immature
lacewings hatch within a few days. lacewing larvae are reddish cream in
color and are tapered in shape like tiny 1/8 inch alligators. When the
larvae mature they form a yellow silken cocoon in which to pupate.
In the larval stage lacewings are ferocious feeders, and consume large numbers of aphids and other insect pests, for example moth eggs.
