Fireflies are beetles that glow! Fireflies are black beetles with big eyes. Most fireflies have wings. They can light up in the dark. Even the eggs of fireflies glow!

Why do fireflies light up? Sometimes, animals want to eat fireflies. Fireflies light up to tell these animals that fireflies taste bad. When a firefly is scared of something, it lights up. Other times, male and female fireflies talk to each other by lightingup. They can blink on and off.

Fireflies love warm areas. Sometimes, you can see them near ponds and forests!
