full size The Common Eastern Firefly belongs to the insect order Coleoptera.

Unlike the Goldenrod Soldier Beetle or the Margined Leatherwing, the pronotum (a plate over the thorax) covers the head of the beetle, so the head is usually hidden from view.

Fireflies use lighting signals to communicate for mating.

The female of the Pennsylvania Firefly mimics the flashes of the Common Eastern Firefly, luring males of the latter and eating him.
