Common Eastern Firefly (Big Dipper Firefly)

Photinus pyralis


A Common Eastern Firefly hitching a ride on my bootlace.


Entrance to a Woodland Trail


Flash is distinctive: male hovers about two feet (0.6 m) above ground, then drops vertically, gives single prolonged flash as is ascending, then flash diminishes (4). Flashing occurs at dusk, earlier in evening than most other fireflies.
