The lovebug Plecia nearctica is a species of march fly found in parts of Central America and the southeastern United States, especially along the Gulf Coast.[2] It is also known as the honeymoon fly or double-headed bug. During and after mating, matured pairs remain together, even in flight, for up to several days.[3]\r\n\r\nThe species was first described in 1940 by D. E. Hardy but was seen in Louisiana as early as 1911.[4] He reported the incidence of lovebugs to be widespread, but most common in Texas, Florida, Alabama, Mississippi, and Louisiana.[2] However, by the end of the 20th century, the species had spread heavily to all areas bordering the Gulf of Mexico and Georgia, and South Carolina. L. A. Hetrick, writing in 1970, found the bug was also widespread in central and northern Florida and described its flights as reaching altitudes of 300 to 450 meters 980 to 1,480 ft and extending several kilometers over the Gulf.[5]\r\n\r\nLovebugs` larvae feed on partially decayed vegetation in the landscape and, in this respect, are beneficial to humans. Adults primarily feed on nectar from various plants, particularly sweet clover, goldenrod, and Brazilian pepper.[2]
