Common green lacewing (Chrysoperla carnea) is a very common, medium-sized, net-winged insect. It occurs in Europe, Asia, North Africa, and North and South America. True to its common name, it is the most common green lacewing (family Chrysopidae).
Adults have a long, slender, pale green body, long antennae, gold or copper-colored eyes, and transparent wings with a network of pale green veins. They are not predacious, feeding on flower nectar and pollen and on aphid honeydew. They are active at night and are attracted to lights. They may emit an unpleasant odor when handled.
Larvae are alligator-like in appearance. They have long, sickle-shaped mandibles and well-developed legs which allow them to move quickly. They are predacious, feeding mostly on aphids but also on many other insect adults, larvae, and eggs.
