    Moths are supposed to be nocturnal aren't they? So why the hell are they attracted to lights?

    I don't think they actually know.

    This is my hypothesis. lying bleeda.

    One hypothesis advanced to explain this behavior is that moths navigate by maintaining a constant angular relationship to a bright celestial light, such as the Moon. The Moon is so far away, that even after traveling great distances, the change in angle between the moth and the light source is negligible. However, when a moth encounters an artificial light and uses it for navigation, the angle changes noticeably after only a short distance. The moth instinctively attempts to correct the angle by turning toward the light, which results in a spiral flight path that gets closer and closer to the light source.
    In 1972, Henry Hsiao, now professor of biomedical engineering, suggested that the reason for moths circling lights may have to do with a visual distortion called a Mach band [1]. Henry Hsiao conjectures that moths, as nocturnal creatures, fly towards the darkest part of the sky in pursuit of safety and are thus inclined to circle ambient objects in the Mach band region. This hypothesis is not scientifically accepted and has never been confirmed. It should be noted that many moths fly directly towards light source, which seems to contradict this hypothesis.

    The navigation theory is disputed, apparently moths don't need to navigate anywhere, they just follow the scent of pheromones to find a mate, or the scent of flowers to lay their eggs.

    Maybe lit lightbulbs smell like male moths then.


    Has anyone witnessed them attracted to the new stupid energy saving lightbulbs, or halogen lights? because i've just had a thought, i've not seen a moth in the house ever since we've replaced all our 'old' type lights.

    Yeah, and what about when the Moon is not in the sky at night as well? They wouldn't be able to navigate then if the needed it to do so.

    I hate them, they are ugly and have funny heads and want to tangle themselves in my hair.
