Insects are inherently drawn to and fascinated by light sources, and they may even collide with light bulbs that are turned upside down. As a result, we'll go over the reasons why flies and insects in general are drawn to light, which include:
Although flying insects such as flies and moths are known to do so, scientists have yet to find out why insects are drawn to light. They have, however, proposed various suggestions as to why insects behave in this manner.
Insects Travel around by Using Light
Many people believe that insects use natural light sources like the moon or the sun to help them travel, thus when an insect sees your porch light, they will fly towards it. If they mistake a butterfly or Fly into your porch light for the sun or moon, the butterfly or Fly may become confused and begin circling about the source.
Insects are attracted to lamps because they release a little quantity of ultraviolet light. Many moths eat floral nectar, which has been shown to reflect UV radiation. Some lamps release a little quantity of UV light, which attracts hungry insects which confuse the bulb for a flower.
Getting Away From Predators
Another idea for why insects are drawn to light is that in the natural, light represents a safe haven from potential danger. When an insect sees light, it assumes there are no predators or impediments in its way. This could also explain why pests seek up light sources directly. And it appears that they clash with lamps and lanterns by accident.
