Green Lacewings Chrysopidae

Green Lacewing
Chrysopidae

Identification: Similar to Brown Lacewings Hemerobiidae. Green Lacewings are larger, with much longer wings. There is not much variation in wing veins among all the species. However, some species do have black cross-veins.

Size: 12 to 20 mm

Life Cycle:
Females create a long, thin stem or stalk and place an egg on the tip of the stalk. The eggs are laid in a straight row and appear almost like teeth in a comb. Larvae use mandibles to suck juices from insects, mostly aphids. After consuming an aphid, the larva will cover itself with the leftovers, or use other debris. Adults have chewing mouth parts and eat the same foods as the larvae.
Green Lacewings have sensors in the large veins of their wings and are attuned to vibrations like bat radar. They also make elaborate vibrations during courtship, using their abdomens and wings.

Thirteen species of Green Lacewings are listed for Ontario. The common species in southern Ontario (5):
Chrysopa nigricornis
