Description
An adult Lonchoptera bifurcata is about 25 millimetres (1.0 in) long. In North America it can be distinguished from closely related species by having pale-coloured bristles behind the eyes, several bristles on the front of the tibiae of the first pair of legs (other species have a single bristle), and wings with fairly sharp points. There are two colour phases, light tan and black. Dark phase individuals may have a completely dark abdomen or may have pale longitudinal markings on the abdomen.
Habitat
Adults of Lonchoptera bifurcata are typically found around damp lawns and in ditches, while the larvae develop in decaying organic matter.
Biology
In North America, males of this species are very seldom seen, the females producing young by parthenogenesis. This seems also to be the case in other parts of the insect's distribution.
