Bugs are attracted to light mainly due to their natural navigation and orientation mechanisms that rely on light sources. Many nocturnal insects historically used the moon and stars to navigate by maintaining a constant angle to the light, but artificial lights confuse this system. The insects try to use artificial lights as a guide, which makes them circle around or fly toward these sources. Another factor is that some insects may mistake ultraviolet light from bulbs for floral nectar, while others might be drawn because light signifies an open and safe path free from predators. Additionally, light sources can attract insects because other insects gather there, which might indicate mating opportunities or hunting grounds for predators. The behavior is sometimes described as an escape mechanism, a disruption of navigation, or a response to visual cues that would otherwise indicate safety in nature. However, the exact reasons are still subject to ongoing scientific study and may include a mix of the above theories.
