LoveBug
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. 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.
The species was first described in 1940 by D. E. Hardy, though it had been observed in Louisiana as early as 1911. At the time, Hardy reported the distribution of lovebugs to be widespread, but more common in Texas and Louisiana than other Gulf States. By the end of the 20th century the species had spread to all areas bordering the Gulf of Mexico, the entirety of Florida, and had spread as far as Georgia and South Carolina. The species is also present in other countries, including Australia. 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 metres (980 to 1,480 ft) and extending several kilometers over the Gulf.
Lovebugs' 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. The lovebug is considered a nuisance by many motorists, especially in the state of Florida, due to its swarming behavior during the species' mating season.
