Lonchoptera bifurcata is the most common of the four Nearctic species in family Lonchopteridae; all four of the species are in the genus Lonchoptera.
Three key traits of Lonchoptera bifurcata are:
- pale post-ocular bristles (these are the bristles along the back of the eye)
- the presence of more than one bristle on the anterior face of the front tibia
- the wings fairly strongly pointed.
Lonchoptera borealis is similar in the first two respects, but has the wings less pointed.
The other two species of Nearctic Lonchoptera have dark post-oculars and only one bristle on the front of the foretibia.
Synonymns of Lonchoptera bifurcata include L. furcata and L. dubia.
John Klymko comments that Lonchoptera bifurcata is common in disturbed habitats such as lawns and ditches. Coloration of the species varies, with tan most common in the summer, and black in the cooler months.
The species is mostly parthenogenic in the New World, with only seven males ever having been collected in North America.
Brian V. Brown surveyed the meager records of Lonchopteridae from south of the United States. He reported one record from Mexico, one from Nicaragua, and several from Colombia and Peru. Only the Mexican specimen was a male. All were in the genus Lonchoptera.
