What is bioluminescence in fireflies?
Quick Answer
Bioluminescence is light produced by a living organism through a chemical reaction. Fireflies use it to communicate, especially during mating.
The Full Story
Fireflies, which are actually beetles, are famous for bioluminescence: the production of light through a chemical reaction involving luciferin, luciferase, oxygen, and ATP. Different species flash distinct patterns that help males and females recognize each other. In many fireflies, the light appears in the abdomen and can be green, yellow, or orange. The signals are not just beautiful; they are part of a precise communication system evolved for mating. Some firefly larvae also glow, and in a few species the light may help deter predators.
