Well it's a series of reasons really...insects have eyes and in those eyes are like little mirrors. so any light will reflect off their eyes and they pick it up as something interesting so they follow to find out what it is.
A hypothesis is a prediction on what you think will happen. For experiments on insects being attracted to light or heat, a hypothesis could be that insects are attracted to light over heat.
Both, depending on the bug. Some bugs are attracted to heat, like sandflies, and some others are attracted to light, like moths. There are even more things that bugs are attracted to. Mosquitoes are attracted to carbon dioxide, a gas that you produce by breathing out!
Some Moths, Flies they come tords light not the heat
light
hormones
Insects, especially winged insects, are attracted to the bright light emitted from a light bulb. Spiders prey on insects, so the more insects are attracted to a certain place, the more spiders will be present there to eat them.
Probably Gnats
Moths and flies, primarily.
No, certain types of insects like moths and gnats are though.
Insects that use phototaxis are moths and cockroaches. Phototaxis means that these insects are attracted to light and will move towards it.

Nobody really knows why this happens.ANS2:Insects are attracted to flames as well as to fluorescent lights. Fire radiates a lot of heat (infra red radiation) and visible light. Fluorescent lights give off very little heat. That would lead most people to conclude that it is the light, rather than the heat that attracts them.Insect lights use UV light to attract insects to their doom. Insects can see UV light and some insects can detect polarized light.
