The compound is called luciferin. As air rushes into a firefly's abdomen, it reacts with the luciferin, and a chemical reaction gives off the firefly's familiar glow. This light is sometimes called “cold light” because it generates so little heat. ... They eat so many fireflies that they themselves begin to glow.
