Insects actually fly around your lights because they're confused, new study says
A new study published in the journal Nature Communications sought to get 3D flight data from insects, something that hasn’t been done before. Before this study, science had to rely on theories such as lunar navigation, where it was believed insects used light from the moon and stars to navigate, according to Business Insider. Smithsonian Magazine explains that this study expanded on lunar navigation, where insects will turn their backs to the sky where light is emanating, a method that helps them know which way is up and down.
