Fireflies always kept glowing since the time they were tiny little larvae

The reason why they emit light is because of a chemical reaction that takes place inside their bodies

Fireflies possess a chemical called luciferin and an enzyme called luciferase inside their bodies

When luciferin reacts with luciferase and the oxygen in the atmosphere, a combination of yellow and greenish light gets emitted from the abdomen of the firefly

The light that gets emitted from the body of the firefly is produced without the help of heat

For this reason, the light produced from the body of a firefly is also known as “cold light”

The glow of a firefly is a chemical light produced within the body of an organism. Such lights are also known as bioluminescence

Bioluminescence is a type of chemiluminescence, which is simply the term for a chemical reaction where light is produced
