It is called Phototropism. It is active in most plants, some insects (especially nocturnal ones) and some animals.
Phototropism in insect, especially moths has been studied for over a century. There are many theories, but apparently no consensus about why this would develop. Hormones seems to play a role.

When insects fly at night they use light sources such as the moon for navigation. Light from a distant source reaches both eyes with the same intensity. This enables the insect to fly in a straight line with both wings beating at the same rate.
If the light is from a closer source such as a candle or lantern, it changes the insect's perception. The light is perceived stronger in one eye than in the other eye. This causes the wing on one side to move faster. The insect then begins to approach the light in a spiral path, eventually drawing them into the light itself.
One good way to know if an insect is nocturnal is to look at their antennae. Insects with poor eyesight have longer antennae. At night they use these sensory organs to probe their surroundings. Many varieties of beetles have poor eyesight. They use their antennae to move around safely at night

Light means life and it looks like the sun for them. That's why they fly into the lights.
