The light is used to attract prey and members of the opposite sex and to warn off predators. [20] Chemical signals, or pheromones, are the ancestral form of sexual communication; this pre-dates the evolution of flash signaling in the lineage, and is retained today in diurnally-active species.

Smedley, postdoctoral fellow in neurobiology and behavior; and Jerrold Meinwald, the Goldwin Smith Professor of Chemistry at Cornell and also a member of the National Academy of Sciences. While not all adults emit light, all fireflies have glowing larval stages. Hadley, Debbie. New York, Photuris This occurs in specialized light-emitting organs, usually on a female firefly's lower abdomen.
