Actual phenomenon supporting the attraction between lights and bugs

Various theories support the fact of insects getting attracted to light. Out of many, one is known as phototaxis. It talks about the way an insect or bugs move away or towards light. When a bug flies towards a light source, it is positive phototaxis. Thye ones who move away from light such as cockroaches fall under the theory of negative phototaxis.

 Another supporting fact revealed is that there are bugs which follow stars and moon as their path guide at night. As you turn on your bulbs, they mistake it as their guide. You might not know but there are insects which move in an internal navigation system. Flying bugs move in a constant angle to their distant light source (moon). Lighting up an artificial source of light causes distraction in the internal navigation system of these bugs and thus relative angle is lost.
