Fireflies FOCUS Question How do fireflies use light to send messages?

Flash, flash, flash. What is that flashing light? The light is from fireflies. Fireflies are insects that make their own light.

Fireflies are not flies. They are beetles.

Look at the belly of this firefly. It lights up. It gets dark. It flashes! Fireflies light up the night sky!

Fireflies flash while they are flying through the air. They flash to tell each other things. Some flashes mean "hello!"

Fireflies go to other fireflies that flash the same way. A male firefly turns on his light. A female firefly sees him in the air. Do You Know? Some groups of fireflies light up all at once. That would look very bright.
