North Carolina is home to a wide variety of tree frogs from three different genera.
Cricket Frogs – Acris
The Cricket Frogs look really similar but there’s a few ways to tell them apart. The Southern Cricket Frog has a more pointed snout while the Northern Cricket Frog, has a more blunt snout. The Southern Cricket Frog doesn’t have as much webbing on the back legs as the Northern Cricket Frog.

Pine Barrons Tree Frog is identifiable because of its purple stripe from its eye down its side.
The Gray Tree Frogs are identical besides their calls. They also have a yellow / orange marking on their hind legs.
Green Tree Frog has a white line down its side of the face and the side of its body.
The Pine Wood’s Tree Frog has orange dots or spots on the inner back legs.
The Barking Tree frog has much rougher skin than any other tree frog.

Mountain Chorus Frog can be identified by the marking on its back. The mark looks like )(.
The Spring Peeper is distinguished by the X shaped marking on its back.
The Upland Chorus Frog has three stripes down its back. The stripes are often broken.
The Southern Chorus Frog is the darkest of all the Chorus Frogs. It has three stripes that can be broken or even spots.

North Carolina has a good amount of different toad species from three different families.
North Carolina’s true toads kinda all look alike so identifying them can be hard.
The Oak Toad is the most easily identifiable toad out of the group of four. It is the smallest of the group and has a light line down its back. The Oak Toad also has orange on the bottom of its feet. The remaining three species of toads in North Carolina are a lot harder to distinguish between. To identify the differences, you have to look at the top of the head. The Southern Toad has knobs on the back of its head. The Fowler’s Toad’s parotid gland touches its postorbital ridge around its eye while the American Toads’s parotid gland does not touch or connected to it by a spur. Here’s an easy map I found that helps me.
There is only one species of Spadefoot toad in North Carolina.
The Easten Spadefoot Toad is the only species of Spadefoot toad in North Carolina so if the toad has a spade on its foot, its the Eastern Spadefoot toad.
There is only one species of Narrowed Mouth Toad in North Carolina.
The Eastern Narrow Mouth Toad is the only Narrowed Mouth toad in the state. Their narrow head makes them easy to identify.
