Phototaxis is a word you might not be familiar with, but it is the natural instinct to be affected by light sources (positive phototaxis means you are attracted to light, while negative phototaxis means you avoid light). For hundreds of millions of years, insects have evolved in some incredible ways, including the way that they navigate.
Have you ever wondered why certain insects are attracted to light, while other insects are repelled by light?
