Plains Leopard Frog (Lithobates blairi)
Southern Leopard Frog (Lithobates sphenocephalus)

The Southern Leopard Frog has a white spot on its tympanum which can help differentiate the species from the other two.

The Plains Leopard Frogs has a break and an indent near its butt while the North and South Leopard Frog just has a straight line.
