How do fireflies glow?

How fireflies glow. Firefly light is produced under nervous control within special cells (photocytes) richly supplied with air tubes (tracheae).

It has been used as a marker to detect blood clots, to tag tuberculosis virus cells, and to monitor hydrogen peroxide levels in living organisms. Hydrogen peroxide is believed to play a role in the progression of some diseases, including cancer and diabetes. Scientists now can use a synthetic form of luciferase for most research, so the commercial harvest of fireflies has decreased.

What would happen if fireflies lit up?

If fireflies produced that much heat when they lit up, they would incinerate themselves. Fireflies produce light through an efficient chemical reaction called chemiluminescence that allows them to glow without wasting heat energy.
