Why are most bugs attracted towards bright light?

Question

Some of them roam about aimlessly around the light. some sit on it without any fear of getting fried to death. Some of them ( the more disgusting ones) touch the bulb and fall straight down as if it is some kind of a sport and after touching the ground they spring up to do the same thing again. It looks quite funny but is there any biological reason why most bugs do this?

Answer 1

Moths are attracted to it because they are naturally attracted to the light of the moon, its part of their migratory habits. Also, I think they just like to be able to see. The spiders like porch lights because the moths do too, and they eat the moths.

Answer 2

For us, staying oriented upright is easy. Just keeping your feet on the ground and moving forawrd is usually enough, though we can lose our balance when we close our eyes or lose other sensory cues.

For a bug flying through the air, it can be more difficult to remain oriented in a particular direction. Weight hardly exists for them to tell them which way down is. But one sensory stimulus that's there every day is the sun, and it's usually "up".

For that reason, many flying bugs use it as a means of orienting themselves - if they can keep flying "up" some of the time, they can stay in the air with a good view of what's around. You'll notice that crawling bugs don't bother with lights.

At night, they might see another light source much brighter than anything else around, and do the same thing, not knowing what the heck an artificial light is. Hundreds of millions of years of past evolution never presented them with this problem. They just aren't smart enough to realize it's really still nighttime, or that this light isn't a good cue to orient by. It's a reflexive reaction. The dropping down is likely a response to being burned or dazzled, followed by further orienting behavior... poor buggers.

(sorry if this repeats anyone else - I had to take time to reconnect, & may've been beaten to the punch.)

An insect will proceed to hover around a guy made easy source despite if a organic easy source will become available. they do no longer fly in the direction of the solar because of the fact they do no longer comprehend the solar as a easy source, and besides, their food is right here in the international. bugs won't fly to the solar without packing adequate to devour, and the solar is basically too some distance off to be carrying that good sized of a lunch sack. Too heavy, it may weigh a trojan horse down.
