Light production in fireflies is due to a type of chemical reaction called bioluminescence. This process occurs in specialized light-emitting organs, usually on a firefly's lower abdomen. The enzyme luciferase acts on the luciferin, in the presence of magnesium ions, ATP, and oxygen to produce light.
But until recently, the actual chemical reactions that produce the firefly's light have been shrouded in mystery. And scientists like Bruce Branchini at Connecticut College love a good mystery. (Also see Fireflies Are 'Cannibals'âAnd More Surprising Facts About the Summertime Insect.)
