- insects with wings, or insects whose ancestors had wings
The common name scorpionflies comes from the unusual tip of the abdomen of these insects, which is bulb-like and has the appearance of the sting of a scorpion. Scorpionflies, however are quite harmless to humans. They have four long similar wings, and a head that is long and narrow, with chewing mouthparts. A most peculiar scorpionfly that is widespread in eastern North America, and in northwestern Ontario is the snow scorpionfly, Boreus brumalis. The adult is a small insect, no larger than 7.5 mm in body length, and often seen on the surface of snow because of their movement and dark body colour. The larvae feed on mosses and the females do not have wings.
