Northern Leopard Frog (Lithobates pipiens)



Northern Leopard Frog (Lithobates pipiens) is a light-green to greenish-brown frog with circular dark spots on its back, sides, and legs. There is generally a white or yellow color that borders the spots. Most notably, the species has white dorsolateral folds that run from the back of each eye to the end of the body. Northern leopard frogs are found in a variety of wetland habitats, especially in fishless waters including springs, ponds, bogs, marshes, and lakes. The species may forage a far distance from water in old fields and prairies. This species is not actively tracked in the Natural Heritage Inventory Database, but it could be tracked in the future if there is further evidence of its decline.
