The yellow groin differentiates the Pickerel Frog from the Leopard Frogs.Pickerel Frog or Leopard Frog? The shape of the dorsal spots will tell. Or perhaps they won’t. It would be convenient if the dark markings of the Pickerel Frog, Rana palustris, always complied with the description most often attributed to it—squared or rectangular dorsal spots--- but the sad truth is that this is not always so. However, another field marking, that of having a yellow groin and underleg coloring does seem to be a constant. And you can always hope that the frog at which you are looking does have squared dorsal and dorsolateral blotches. Many do.

The Pickerel Frog is rather unique amongst the eastern ranids in that it produces a decidedly noxious skin secretion. The secretion can cause many human tears if the eyes are rubbed before hand washing. The secretion also seems sufficiently repulsive to render the anuran an unsuitable prey item for many snake species.

Overall, this brown spotted 3 ½” long, tan frog is common throughout its divided range. The eastern population ranges westward and southward from eastern Quebec to the eastern shore of Lake Michigan, then southward to northwest Alabama and southeast South Carolina. The western population ranges westward and southward to Western Wisconsin, then to east Texas and South Central Alabama, and Escambia County, FL. Between the two populations is a broad swath of what seems to be Pickerel Frog No Man’s Land.

The snoring call of this frog man be produced when the frog is fully exposed or when it is fully submerged. This frog may be encountered in moist meadows, near or in grassy puddles, bogs, and ponds, and may even enter caves. IOW it may occur wherever you would expect to find a frog and in some places that you might not expect one. They are not hard to find.

BTW, Lithobates is no longer the genus for the eastern ranids. They have been returned to Rana.
