There are various experiments that you can do for why insects are attracted to light and heat. Experiments can be done at night with a light source and heat source in boxes to see which one attracts more insects.

Some Moths, Flies they come tords light not the heat

Bed bugs are not typically attracted to light sources. They are more active at night and are attracted to the carbon dioxide and body heat emitted by humans.
Nothing attracts insects to heat or light, they attract themselves because they are used to the sun or moon by their side. It is a navigation aid for them. so therefore, they aren't attracted by anything.
Insects have evolved in earlier ages in which there was generally no light at night other than the moon, and they navigate with the help of the moon. Lights at night are confused with the moon and lead to navigational error, making it seem that insects are attracted to light.
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.
No they are no, they are actually attracted to light and heat.
YES
Mosquitoes are attracted to carbon dioxide, body heat, and body odor. When it comes to light, mosquitoes are generally attracted to ultraviolet light and incandescent light.
The bugs are attracted by the heat of this light.
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.
