FUN FACT

Why Blink?

The purpose of blinking is so that male fireflies can find potential mates. If you watch long enough you will be able to pick up on their unique flash pattern. Try to remember it so that next time you see a firefly flash you can identify it.

FUN FACT

Making Light

Fireflies combine three special substances in their photic organs to make light. The three substances are: luciferin (a pigment), luciferase (an enzymatic catalyst), and ATP (nucleotide that provides energy to cells). As they breathe in oxygen, it charges this reaction and by regulating the amount of oxygen they take in they can modulate the flash they produce!
