Secondly, the brightness of the light might spark them to respond as they do to sunlight, which is to hide or become inactive. If you have a light on your porch on, you will attract moths that are up to 23 meters away. They found light to act like a vacuum cleaner in bringing all the moths in this radius to the light.
Artificial lighting can cause moths, and other insects, to waste time and energy. This can be particularly problematic for migrating species, for which timing is of the utmost importance. Somehow light confuses moths, though it is unclear exactly why. Most of the research on this matter is older, and new technology would surely help to shed light on this question.
Hopefully, researchers will renew this interest in this question to help settle it once and for all. I've always liked the way that words can sound together.

The era of greyhound racing in the U. In high illumination, light from each of the moth's thousands of fixed-focus lens facets is channeled to its own sensor ommatidium. In low illumination, light from multiple lenses is channeled to the same ommatidium to increase light sensitivity. You probably experience a few moments of blindness when you turn on a bright light after your eyes have adjusted to darkness, or when you are suddenly in darkness after being in bright light.
A moth's dark-adapting mechanism responds much more slowly than its light-adapting mechanism. Once the moth comes close to a bright light, it might have a hard time leaving the light since going back into the dark renders it blind for so long. In the case that the moth escapes, it won't remember the problem with flying too near the light and will probably find itself in the same predicament all over again. Another possible explanation for why moths stay at lights is that they are mostly night-flying creatures and eventually respond to the light as they would to the sun -- by settling in for their daytime "sleep.
