Why Does a Moth Fly Toward a Light?

Years ago, hundreds of moths appeared inside a tiny cabin in the Black Hills. They covered the walls, flew around the beds and held what appeared to be the annual meeting of every moth in South Dakota directly above a terrified three-year-old. That kid...was my stepdaughter.It was chaos—but it also raises a question most of us have never thought very hard about:Why does a moth fly toward a light?The answer is stranger—and much less embarrassing for the moth—than we’ve been led to believe.In this companion episode to my conversation with author Leigh Ann Henion, we explore research suggesting that moths and other flying insects may not be deliberately steering toward artificial light. They may be trying to keep the brightest part of the world above their backs—and becoming trapped when humans put the sky in the wrong place.We’ll also meet moths away from the porch light: moving pollen through the dark, feeding young birds and using some spectacular defenses against hunting bats.IN THIS EPISODEThe night hundreds of moths filled a cabin in the Black HillsWhy moths may not actually be choosing to fly toward artificial lightHow flying insects use light to determine which direction is upWhat happens when humans mount a miniature sun beside the garageThe microscopic scales covering moth wingsThe overlooked work moths do as nighttime pollinatorsWhy moth caterpillars are important food for young birdsThe evolutionary argument between bats and mothsHow a luna moth’s tails can misdirect a bat’s attackThe effects artificial light can have on moths and their caterpillarsSimple ways to return some darkness to the nightKEEP EXPLORINGListen to my conversation with Leigh Ann Henion:What Happens After Dark? - W/ Leigh Ann HenionExplore the full episode companion—with photographs, resources and something to try after dark:What Happens After DarkWhy flying insects gather around artificial light:https://www.nature.com/articles/s41467-024-44785-3Mothing 101 from National Moth Week:https://nationalmothweek.org/mothing-101/Five Principles for Responsible Outdoor Lighting:https://darksky.org/resources/guides-and-how-tos/lighting-principles/YOUR TURNThe next time you see a moth circling a porch light, turn it off for a while if you can.
