This medium-sized frog, is similar to northern leopard frog but spots located between dorsolateral folds along the back are paired and rectangular, not rounded.
General description: The slender pickerel frog has bulging eyes, long legs, a lanky body, two big ridges between its back and sides, and smooth skin.
Size: Pickerel frogs are 1 3/4 to 3 1/4 inches long.
Color: The pickerel frog has a pale brown background with brown spots in rows on back. Its underside is light-colored with yellow where the legs and body connect.
Sounds: Quiet, long drawn-out snore. Similar to the northern leopard frog, but lacking the chuckle at the end.
Pickerel frogs begin to reproduce at two years of age. In spring males begin calling to attract females. The female lays a blob of 700 to 3,000 eggs in the water. It takes about two weeks for the eggs to hatch and 8 to 11 weeks for tadpoles to develop into frogs.
