Why are nocturnal insects (i.e. moths, beetles, etc) attracted to light?

They are programmed to spiral around the moon. \nThis keeps the insects evenly dispersed across the land and  helps to prevent inter-beading. But lights are brighter than the moon and fool them.\nIf you watch them move towards the light, you should notice that they spiral towards it.

" due to my interest into animals sleeping patterns, i have decided to investigate in to whether artificial light could affect the way that certain animals sleep. To carry out this investigation i will do the following ...... \nMy hypothesis ( theory / idea to the outcome) would be that artifficial light does ....\nsomething like that should give you a start

they hide in places you never look in.  flies, like many other bugs, are active during daytime when it is warm. at night, when it is cool, they rest in sheltered areas like under the roof, in pipes, on the walls.  moths and other night bugs do the opposite.

Although there is still debate among scientists on this point, most believe moths are attracted to the light because they use the moon to help orient their flights. Such distant points of light allow the insects to fix their flights by maintaining a constant angle to the light source. Artificial lights confuse the insect response, since these lights are so close (an unnatural situation). Trying to maintain the flight angle to these close light sources cause the insects to spiral to the source.

normally bats are nocturnal,,,,normally there most of the activities are in night,,,,,,, but they do fly in day,,,,,,, only for migration becoz they cannot tolerate extreme cold temperature,,,,, they can migrate in day for better habitat

The purpose of the glow varies. Those adult females which glow do so to attract a male for mating. The Lampyridae larvae are believed to glow to warn predators like toads not to eat the larvae as they're mildly toxic. But the Arachnocampa larvae on the other hand glow to attract prey like midges into sticky snare lines for the larva to feed on.

Not only the colors and scents, but some flowers emmit "smell alike" pheramones to attract certain sex of insects.\nIn addition, its also been found that not only the color of the flower attracts the insects, but also the ultraviolet radiation that certain flowers colors give off. Certain flowers colors give off colors that only the insect can see, almost like looking at a 1960's poster under a black light. They see certain colors or patterns and go for the flower.

Fireflies produce a protein called "luciferin" which can be chemically modified (oxidized) by another protein called "luciferase".  When this reaction occurs, energy is released in the form of light.  This phenomenon is known as "bioluminescence" and occurs in many different species.

There is no one reason why bugs are attracted to light. All of the following are possible in my opinion:\n\n1) Bugs use light to navigate. The moon is a very long way from us by normal standards and the light rays which reach the earth are virtually parallel. By flying at a constant angle to these rays it is possible over a short period of time to fly in a straight line. When an insect is close to a lamp the rays are not parallel, but divergent. The effect of keeping the rays at a constant angle will be to fly round the light source.\n\n2) Many bugs see ultraviolet light and may be attracted to flowers at night which reflect ultraviolet patterns using moonlight. Lights which emit UV rays may therefore attract such insects.\n\n3) Both or one of the above reasons are often given by entomologists to explain the attraction to light. It is also possible, although I have never seen research on this, that bugs are attracted to the heat of the light source.

they are in fact attracted to the dark area around a bright light source - the contrast makes it look like a tasty bit of shade.\n\nand there is a theory that many moths from before the time of the candle or electric light bulb, are on their way to the sun right now :)\n\nwickid :)

If insects are so obsessed with bright lights, why don’t they fly off to the sun?\n\nI think they probably have some depth perception and so realize that it's too far off.  \n\n\nWhat happens if you die in your dream?\n\nNothing; you go on living.  I don't think it's a bad omen or anything like that.\n\nWhy do people more commonly skip breakfast than any other meal, considering that this is the time when the stomach is emptiest?\n\nPeople are so often in a rush in the morning that they don't take the time.  A shower so you don't smell at work seems to be more important than fixing a bowl of cereal.\n\nIf same-sex couples could marry, what would happen to their surnames?\n\nThey would probably just both keep their own name or do a hyphenated name...just like a lot of straight couples do.\n\nHow are children supposed to take medicine if it’s meant to be kept out of their reach? \n\nUh...their parents give it to them.

The substances that are necessary to produce the light emitted by the firefly are oxygen from the air and two chemicals. These chemicals are called luciferin and luciferase. They are produced in the luminous organ that is located in the end segments of the insect's body. \n\nThe tissues of this organ are penetrated by a network of fine tubes that are connected to breathing holes along the edge of the body. The breathing holes perform the same function as nostrils do in higher animals. \n\nThe chemical process that releases light is quite complex. Luciferin is oxidized in the presence of the enzyme luciferase, which acts as a catalyst for the reaction. \n\nThe reaction produces an excited form of luciferase. When the excited form returns to the normal form, the chemical change is accompanied by the emission of light. The firefly controls the chemical changes that occur in the luminous organ.

Check these factors out\n\n1.  The amount of pollutants in the air are lower at night\n2.  The amount of oxygen released by plants is maximum at night and C02 levels are least reduced.\n3.  Humidity levels are generally high at night\n4. Charged particles are less at night, because there is no more "ionizing" sunlight (smell is an electrochemical process\n\nI could think of other reasons, but I'm out of ideas.

You reminded me of my childhood days. I used to ask my father the same Questions.\n\nClouds don't go any where during night. They are still there it only that there is not enough light for us to see them. Remember when you see moon light we see those clouds around or sometimes the moon hiding behind the clouds.

These bacteria probably have the lux gene which codes for bioluminesence. A resonable mechanism that would cause this to arise is mutation. These lighted cells would probably have benefited some how from glowing in the dark. Some deep sea fishes have bacteria which code for this gene (Vibrio fischer) Which may have helped these fish find food in the dark waters. Thus those fishes without this gene would have died out because of natural selection. What you could do is put these fishes with the bacteria that glow in the dark in the same pool of dark water as the fishes without this gene. Then provide a limited food source so that not everyone could receive food and only the strongest would survive. If the fishes without this bacteria eventually died out but the others stayed alive, you have proven your hypothesis. If not, then failure willl be an obsticle to overcome.\n\nHope i was helpful

Fireflies produce a chemical substance called luciferase that reacts with the oxygen in the air to give off light.  When they let air into their abdomen it glows.  They glow for two reasons.  To attract mates, and to attract other tasty bugs for food.  Depending on the species, fireflies can serve as good thermometers.  They flicker on and off at different rates depending on how cold it is.  By the way, I'm not southern and I usually call them lightning bugs and I don't usually kill them because they probably eat mosquitos...I hate mosquitos.

They could be feeding at that spot at night ,or they could smell you in your stand or they may not be used to the stand and it spooks them if its new to the area,Best time of day i feel is just starting to get light or just starting to get dark deer are usually on the move to or from bedding and feeding sites
