Adult fireflies have a special light-producing tissue inside the abdomen covered by a very thin, translucent exoskeleton; this allows the internally produced light to shine through. The world is full of questions we all want answers to but are either too embarrassed, time-crunched or intimidated to actually ask.
In a firefly's tail, you'll find two chemicals: luciferase and luciferin. Luciferin is heat resistant, and it glows under the right conditions. Luciferase is an enzyme that triggers light emission. ATP, a chemical within the firefly's body, converts to energy and initiates the glow.
