Frogs and Toads of Delaware
For a small state, Delaware is home to a variety of frogs and toads.
There are two different families of frogs, tree frogs and true frogs in Delaware.
Spring Peeper (Pseudacris crucifer) has a noticeable x mark on its back.
The New Jersey Chorus Frog has stripes down its back.
Eastern Gray Tree Frog (Hyla veriscolor) and Cope’s Gray Tree Frog (Hyla chrysoscelis) are basically identical species. The difference between them is the calls. You can identify them from the others because of the yellow or orange marks on their back legs.
Here is a video I took of some calling
Barking Tree Frog has rough skin compared to the Green and Gray Tree frogs.
Green Tree Frog (Hyla cinerea) has a white line down the mouth and side that separates it from the other tree frogs in the state.
Northern Cricket Frog (Acris crepitans) is the only cricket frog in the state. They have no distinct markings on their back.
The Green Frog and American Bullfrog looks the same but the Bullfrog can grow larger and they lack a dorsal ridge down their back.
The Pickeral Frog and the Southern Leopard Frog look very much a like. The Pickeral Frog has more square shaped spots on its back while the Southern Leopard frog has more circular ones.
Carpenter Frog is easily identifiable because of their brown color and two yellow lines that run down their back.
Wood Frog (Rana sylvatica) has a raccoon mask around its face which no other frog in the state has.
Fowler’s Toad has a clear, white belly while the American Toad has a more speckled one.
Eastern Spadefoot Toad is the only spadefoot toad in the state so just look for the toad with a spade on its rear feet.
Eastern Narrow Mouthed Toad (Gastrophryne carolinensis) is the only narrowed mouth toad in the state. Their small, pointy head is a key characteristic of the species.
