"Phototaxis is an organism’s automatic movement toward or away from light. So a cockroach has negative phototaxis, because it’s always scuttling into dark corners while a moth has positive phototaxis because of it’s preference for bright lights.
Why are they attracted to bright lights?
We have several theories but no definite answers. Here are the theories:
- Moths use the moon as a primary reference point to travel. So it’s attraction to the light maybe related to that orientation and cause disorientation.
- Moths may see flying towards the light as advantageous and safer than flying somewhere dark.
Did you know moths are sensitive to ultra-violet light? A white light will attract more than than a yellow one."
