common eastern firefly

Have you ever caught a firefly on a warm summer night? Chances are it was a common eastern firefly (Photinus pyralis). Like most fireflies, it communicates with patterns of flashing light. These signals are used to find and attract mates, deceive other firefly species, and avoid predators. While many organisms make their own light, called
bioluminescence, fireflies are perhaps the most familiar.

Scientific Name: Photinus pyralis
Habitat: grassy areas in eastern North America
Diet: other insects, earthworms, and snails
Size: adult male is 0.4 inches (9-10mm) long
