Green lacewings are insects in the large family Chrysopidae of the order Neuroptera. There are about 85 genera and (differing between sources) 1,300–2,000 species in this widespread group. Members of the genera Chrysopa and Chrysoperla are very common in North America and Europe; they are very similar and many of their species have been moved from one genus to the other time and again, and in the nonscientific literature assignment to Chrysopa and Chrysoperla can rarely be relied upon. Since they are the most familiar neuropterans to many people, they are often simply called "lacewings". Since most of the diversity of Neuroptera are properly referred to as some sort of "lacewing", common lacewings is preferable.
Green lacewings are delicate insects with a wingspan of 6 to over 65 mm, though the largest forms are tropical. They are characterized by a wide costal field in their wing venation, which includes the cross-veins. The bodies are usually bright green to greenish-brown, and the compound eyes are conspicuously golden in many species. The wings are usually translucent with a slight iridescence; some have green wing veins or a cloudy brownish wing pattern. The vernacular name "stinkflies", used chiefly for Chrysopa species but also for others (e.g. Cunctochrysa) refers to their ability to release a vile smell from paired prothoracal glands when handled.
