New Jersey chorus frog (Pseudacris feriarum kalmi)


This is a small frog with three broad, well-defined, dark stripes on the back, and a broad, dark stripe along its side from the nose to the rear end that passes through the eye. It grows to a length of 3/4-1 1/2 inches (2.9-3.9 cm). This frog always has a light line along the upper jaw. This mark differentiates it from the spring peeper, Hyla crucifer crucifer, which usually has an X pattern, rather than stripes, on its back. The upland chorus frog, Pseudacris feriarum feriarum, usually is weakly or thinly striped or has spots rather than broad, bold stripes. The base color is usually dark brown to light gray, but may be greenish, and the markings are brown to gray. The belly is whitish, sometimes with a few darker spots on the throat and chest.


This frog is found only on the Eastern Shore in Virginia. It occurs in the Coastal Plain from Staten Island, New York, to the southern tip of the Delmarva Peninsula. This is a woodland frog that inhabits hardwood and mixed pine-hardwood forests where there are ponds, ditches, and streams that can be used for breeding.


A member of the family of chorus frogs, this species will climb into weeds or low shrubs in pursuit of insects.
