Why are night insects attracted to light?

Introduction: The Mystery of Night Insects and Light

The sight of swarms of insects gathering around a light source during the night is a common phenomenon. This peculiar behavior has puzzled scientists for centuries. Why are night insects attracted to light? It is a question that has fascinated entomologists, biologists, and researchers across various fields of study. Insects are known to be sensitive to light, but what makes them swarm around light sources remains a mystery.

The Science Behind Insect Vision

Insects have compound eyes that are made up of thousands of tiny lenses. These lenses help insects detect light, colors, and patterns in their environment. Insects can see different types of light, including ultraviolet light, which is invisible to the human eye. This ability to perceive ultraviolet light is crucial for insects when it comes to finding food, mates, and avoiding predators. Insects are also sensitive to the polarization of light, which helps them navigate and orient themselves in the environment. Their eyes are highly sensitive to light, which is why they are attracted to bright sources of light during the night.
