Everyone knows that light insects. In prehistoric times, our ancestors why winged insects buzzed around fire. An old saying this attraction as being, "like a moth to a flame". However, a recent study the long-believed notion that insects towards light because they it. Biologists at Imperial College London have reported that insects are to light because it helps with their orientation when in flight. The scientists said artificial light actually nocturnal bugs like moths and mosquitos, often to fatal ends. Jamie Theobald, co-author of the study, said all our speculations about why insects toward light "might have wrong".
The scientists their research in a rainforest in Costa Rica. They artificial lights under the canopy and observed the creatures' flying behaviour. Insects usually by the moon to fly in straight lines. However, around the artificial lights, the bugs became confused and made arcs and erratic patterns of flight. An entomologist said: "Natural sky light…helps proper flight….Artificial sources…can produce continuous around the light and an insect." This why so many insects fly to their death into bug zappers. Artificial light adversely an insect's ability to a mate, for food, and defend itself against predators.
