The locomotion of insects towards a light source is called "positive phototaxis." This behavior is driven by the insects' attraction to light, which can aid in navigation and finding food or mates. Positive phototaxis is commonly observed in various species, particularly moths and other nocturnal insects.
fireflies
A small light source is called a flashlight or a torch.
An insect light attracts and traps insects effectively by emitting ultraviolet light that is attractive to insects, luring them towards the light source. Once the insects get close to the light, they are either electrocuted by the light or trapped in a sticky surface, preventing them from escaping. This method is successful in capturing a wide range of flying insects.

A ray emitted from a light source is called a light ray. It represents the path that light travels in a straight line from the source in a specific direction.
Our sun is the source.
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.
Yes - the luminescence is produced by a chemical reaction within the insects body.
When hear energy is converted to loght energy it is called hot source of light (sun light). when light source is produced from (generally reflected light, moon light) a cooler object.
Light source, can be mirror or electric light.
The mirror, which can also be called the light source. It reflects the light.
This phenomena is called metamerism. It occurs when two colors appear to match under one light source but not under a different light source.
