If moths so attracted to light why not come out in the day?
Answers:
They are shy
because they are the handmaidens of the devil
because that is not when the food is out.
Because they are attracted to small concentrtions of light - In the daytime everything is light
they do
I read somewhere, that moths are not actually attracted to the light, but to the darkness around the light, and also they are instinctly looking for food which is at night

Wake me up when this question is no longer being asked.
May be, they want only a small source of light.
They must be getting irritated by the whole earth being lite up by the sun. !!
Dunnow jus a guess
Night flying creatures are often only avoiding predators, such as birds. Of course birds (owls) and bats have adjusted too! The attraction to light is probably to do with attraction to the moon, often associated with breeding cycles, (not bicycles).
Lots of them do. Our gardens aplenty at the mo with dayflying moths, some are very pretty.
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.
Mach bands are an optical illusion named after Ernst Mach. It refers to bands adjacent to a light to dark gradient that appear lighter or darker than justified by the underlying light.
The effect is one of increased, local, perceived brightness on either side of a luminance gradient. It is usually supposed that this effect is caused by lateral inhibition of the receptors in the eye. An alternative explanation is that the effect is explained by the fundamentally statistical strategy of visual perception, representing the common occurrence of highlights and lowlights in association with luminance gradients.
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.
Night-blooming flowers usually depend on moths (or bats) for pollination, and artificial lighting can draw moths away from the flowers, affecting the plant's ability to reproduce. Light pollution is coming under increasing scrutiny as a source of many subtle ecological changes.
Some claim that, to the moth, bright lights mean open space and open space means safety. But moths are nocturnal, and the night sky has no light sources anywhere near as bright as a porch light. Besides, why should the moth feel compelled to fly around the light in circles? Others argue that moths associate light with warmth. Yet ultraviolet lamps, which are much cooler than incandescent bulbs, attract more moths.
Moths exhibit two kinds of behavior. When they're distant from a light source (they're drawn to light from as far as 200 feet away), they make a beeline straight toward it. Why, nobody knows. Maybe they've tumbled to the fact that lights mean people, and people mean: Wool sweaters! On an even more basic level, a light means: Other moths! Par-ty!
However, when the moths get close to the light, a different kind of behavior takes over. Instead of being attracted to the light, the moth is actually trying to avoid the light. When you think about it, this is only natural. To a creature of the night like a moth, daylight and by extension any bright light means danger. The moth doesn't fly directly away from the light due to a peculiarity of vision called a Mach band. A Mach band, which apparently is common to all sighted creatures, is the region surrounding a bright light that seems darker than any other part of the sky.
The moth's atom-sized brain figures the darkest part of the sky is safest. So it circles the light in the Mach band region, usually at a radius of about one foot, depending on the species. Eventually either its momentum carries it away or it finds a dark corner to hole up in.
In short, moths like some light but not too much--just like other creatures I could name. Nobody wants to get burned, naturally, but at some point in our lives, aren't we all attracted to those bright porch lights?
I was told that moths navigate by the moon - they fly at a fixed angle to it, which works because the moon is so far away, they end up flying in basically a straight line - the slight curve caused by this method doesn't matter. When they fly at a fixed angle to a light source much closer, they end up going in circles! In other words, they have a 'simple program' which worked when the moon was the only bright source of light, but which doesn't cope with man-made lights.
