Why Are Moths Attracted To Light?
Why are moths attracted to light?
MOTHS can be seriously annoying if they start munching your clothes or hovering around your bedtime reading lamp. But what are they so attracted to light and how can you get rid of them? Here's what you need to know. Some insects, such as moths, navigate by flying at a constant angle relative to a light source, such as the moon, keeping them flying in a straight line. But, when it comes to finding their way around man-made lights, the angle to the light source changes as a moth flies by which confuses it. Moths only have mouths during their larval stage, which usually lasts between two weeks and a month.
To understand this phenomenon, you need to know about phototaxis. Phototaxis is an organism's automatic movement toward or away from light. Cockroaches are an example of a negatively phototactic organism. You've probably noticed how they scurry back into dark corners and crevices when you illuminate their late-night snacking party in your kitchen. Moths are positively phototactic. They seem charmed by your porch light, your headlights or your campfire even if it leads to their untimely demise.
The old saying "like a moth to a flame" describes someone with an unswerving yet self-destructive attraction. Where people are concerned, the underlying motivation for such behavior can usually be identified, whether it's greed, lust or the thrill of the chase. Not so with moths. There are a handful of theories as to why the insects make their suicidal nosedives toward burning candles and artificial lights. But, perhaps surprisingly, that's all they are — guesses. And they're not particularly good ones, either.

All rights reserved. Often, creatures entranced in such a glow get eaten by predators or overheat. Like the tragic tale of Romeo and Juliet, the story of the lamp and moth is one of fatal attraction. Being primarily nocturnal creatures, moths evolved to travel by the glimmer of the moon, by a method called transverse orientation. Indeed, the day that Thomas Edison patented the lightbulb—January 27, , which paved the way for global distribution of electric illumination—was a dark day in moth history.
