The interval between flashes is generally shorter with warmer temperatures. The air temperature can influence the frequency of flashing. The light flashes can vary from yellow to green colors, depending on the species. Chemicals, such as luciferase and luciferin, work with other substances in the insect’s body to produce light very efficiently, without generating heat. The often bright light-bioluminescence-produced by adult fireflies is from light-producing lantern organs in their abdomen. They are not true flies but nocturnal beetles. To protect fireflies and ensure that we continue to enjoy their presence in the landscape, it is important to understand their lifecycle and habitat needs.įireflies belong to insect family Lampyridae. Also known as lightning bugs, the insects’ “dancing light” patterns are an important, and nostalgic, part of Georgia summer evenings. In late March to early April, adults leave their overwintering sites to return to their host trees for the warmer months.Georgia is home to over 50 species of fireflies, more than any other U.S. These black and orange bugs tend to hide in small cracks and crevices in walls to insulate themselves from the cold winter temperatures. After large masses gather, they migrate to nearby buildings or homes to overwinter. In the fall, boxelder bugs become gregarious and congregate on the south side of rocks, trees and buildings where the sun hits. There are two generations per year in the warmer regions of the United States. The nymphs feed on fallen boxelder seeds and later on new leaves. The eggs turn red as the embryos develop and hatch about two weeks later. The females lay clusters of straw-yellow eggs on stones, eaves, grass, shrubs and trees – especially in the bark crevices of boxelder trees. Occasionally, these black and orange bugs will feed on the fruits of plum and apple trees. They first feed on fallen boxelder seeds and later move to the female boxelder trees or maple trees where they eat newly developing leaves. During this time, the adults leave their overwintering sites to return to their host trees for the warmer months. Overwintering adult boxelder bugs emerge from hibernation in late March to early April when the boxelder buds open. Since they can attract other pests, it’s an infestation best to avoid dealing with on your own. If a boxelder bug infestation is suspected, a licensed pest control professional should be contacted to evaluate and assess the problem. For light fixtures and ceiling fans, remove the fixture to its base plate, seal and replace. For electrical outlets, switch boxes, heating ducts and return air vents, remove the coverplate, seal and replace. Then, seal up any entryways into the living space – window pulleys, window and door frames, baseboards, etc. The bag should be removed to prevent the bugs from escaping. To provide temporary relief during this time, consider using a vacuum cleaner to get rid of the boxelder bugs. Experts recommend waiting until summer when all live overwintering adults are out of the wall voids. No attempt should be made to kill them in wall voids, because dead insect bodies can attract dermestid beetles (larder beetles, carpet beetles, etc). If you do find an infestation of black and orange bugs and need to get them out of your home or other building, be careful of DIY efforts to kill them. The good news is that a boxelder bug is nothing to fear - their presence can simply be a nuisance. Installing door sweeps to all exterior entrances.Sealing cracks and crevices with a good quality silicone or silicone-latex caulk.Repairing holes in window and door screens.Several steps can be taken to prevent boxelder bugs from invading homes.
