Why do fireflies glow at night?

Quick Answer
Fireflies glow because they produce light through a chemical reaction called bioluminescence. The light is used mainly to find mates and signal to other fireflies.
The Full Story
Fireflies create light in special organs using luciferin, luciferase, oxygen, and ATP. This reaction produces a very efficient cold light with little heat, which is why it glows rather than burns. Different species use different flash patterns, and those patterns help males and females identify each other. Some larvae and eggs also glow, not just adult insects. Bioluminescence evolved independently in several groups of animals, but fireflies are among the most familiar examples.
