Plains Leopard Frog (Lithobates blairi)
Description: 2 - 3½ inches. Plains Leopard Frogs are tan or brown in color, with large dark spots. There is usually a light colored spot on the ear drum (tympanum). There are ridges that start behind each eye, and run down most of the length of the back (dorsalateral folds), but are broken and inset near the legs. There is a light colored line on the upper lip.
Similar Species: The dorsolateral folds on Northern Leopard Frogs and Southern Leopard Frogs are unbroken and not inset. Crawfish Frogs have a marble patterned lip rather than having a light line on it.
