Chrysopa rufilabris is a member of the Family Chrysopidae, which contains the common lacewings, with 27 North American species. Lacewings typically have a pale greenish body and often have golden eyes. The wings are transparent and characterized by numerous cross veins. These lacewings commonly occur in fields, where their larvae can feed on aphids. Adults lay their eggs on the underside of leaves, and the eggs are attached to a projecting, threadlike filament. Once the eggs hatch, the larvae emerge and begin to feed immediately. The larvae are voracious predators, and their preference for aphids has earned them the nickname “Aphid Lions”. The larvae have large pincers and often cover their bodies with debris and pieces of their prey as Ameans of camouflage. The larvae of C. rufilabris are frequently used as a means of biological control of agricultural pests.
