The world is full of questions we all want answers to but are either too embarrassed, time-crunched or intimidated to actually ask.
The mechanism by which fireflies turn their light production on and off is not well understood, but there are several theories. Some scientists think that fireflies regulate light production by controlling the amount of oxygen supplied to their photic organs. Others think that bioluminescence in fireflies in under the control of the nervous systems. It is important that fireflies and other bioluminescent organisms are able to tightly control their light production. This allows the light to act like a language
