Originally posted by BrianR I would also lean towards leopard as the spots I can see don't look very squarish, but there is a great deal of variation in both species and I'm certainly more familiar with my local populations
For comparison with the latest batch of Leopard frogs, Here is a Pickerel Frog, no green coloration and squarer spots. I see lots of Pickerels in northern Delaware but have not seen a southern Leopard frog even though they are supposedly common here. It does not show in my picture but pickerels have yellow on the belly near and under their hind legs. I think they may also have a shorter snout than leopards.
