Tree Frogs – Hylidae

Eastern Gray Tree Frog (Hyla veriscolor)

Some Eastern Gray Tree Frogs calling.

The only two tree frog species in the state are the Spring Peeper and  the Grey Tree Frog. The Spring Peeper is a lot smaller than the Grey Tree Frog and contains an x on its back that the Grey Tree Frog does not have.

True Frogs – Ranidae

Green Frog (Rana clamitans)

American Bull Frog (Rana catesbiana)

The American Bullfrog and the Green Frog look pretty much alike besides the American Bullfrog grows larger and that the Green Frog has a incomplete dorsal ridge but the American Bullfrog does not have a dorsal ridge.

Northern Leopard Frog (Rana pipiens)

Pickeral Frog and Northern Leopard Frog look very similar to each other because of the spots but the Pickeral frog’s spots are more rectangular than the Northern Leopard Frog.

Wood Frog (Rana sylvatica)

The  Wood Frog is easily identified by its dark mask around its eyes.


True Toads – Bufonidae

American Toad (Anaxyrus americanus)

The difference between the Fowler’s Toad and American Toad involves the head. In the American Toad, the parotoid gland the the crest behind its eye does not touch while the Fowler’s Toad has them touching.
