The Common Green lacewing's name refers to its distribution in Europe, where it is one of or is the commonest species found there. In Alberta "Common" does not apply as well, and is generally overshadowed by more common Chrysopa species. In winter C. carnea turns rosy-brown with a pale stripe down half of the body. Unlike most Green lacewings this species does not make a home from assorted debri as a larva. In Europe this species is apparently the worst enemy of Aphids and its relatives. This species used to be called Chrysopa carnea and was moved to the genus Chrysoperla at a later point.
Adult length including wings is about 10mm-13mm.
