The death of the moth thesis

Moths frequently appear to circle artificial lights, although the reason for this behavior remains unknown. One hypothesis to explain this behavior is that moths use a technique of celestial navigation called transverse orientation. By maintaining a constant angular relationship to a bright celestial light, such as the moon, they can fly in a straight line. Celestial objects are so far away that, even after travelling great distances, the change in angle between the moth and the light source is negligible; further, the moon will always be in the upper part of the visual field, or on the horizon. When a moth encounters a much closer artificial light and uses it for navigation, the angle changes noticeably after only a short distance, in addition to being often below the horizon. The moth instinctively attempts to correct by turning toward the light, thereby causing airborne moths to come plummeting downward, and resulting in a spiral flight path that gets closer and closer to the light source.

Sophia also describes how the project made her feel more confident about her love of bugs. "It felt good to have so many people support me, and it was cool to see other girls and grown-ups studying bugs. It made me feel like I could do it too, and I definitely, definitely, definitely want to study bugs when I grow up, probably grasshoppers," she wrote. Sophia has even managed to open the eyes of some of her peers since going viral: "I told my best friend and her sister about bugs, and now they think they're cool, and her sister will pick up any bug! I think other girls who saw my story would like to study bugs too."
