The lovebug, Plecia nearctica, is a member of the family of march flies. It is also known as the honeymoon fly, telephonebug, kissybug or double-headedbug. The adult is a small, flying insect common to parts of Central America and the southeastern United States, especially along the Gulf Coast.
The lovebug was first described in 1940 by D. E. Hardy from Galveston, Texas. At that time, he reported the incidence of lovebugs to be widespread, but most common in Texas and Louisiana. By the end of the 20th century, however, the species had spread heavily to all areas bordering the Gulf of Mexico, as well as Georgia, and South Carolina. L. A. Hetrick, writing in 1970, found it very widespread in Florida and described its flights as reaching altitudes of 300 m to 450 m and extending several kilometers over the Gulf. In 2006, it was reported as far north as Wilmington, North Carolina.
