The distinguishing characteristic is the ridge that starts at the back of the
eye. Bullfrog - it curves around the eardrum, greenfrog - it runs down the
back.

Don't forget the big difference in voice. Green frogs sound
distinctively like the twang of a banjo string.

has a list of frogs native ot your area with audio sound clips for each.

I find it a lot easier to distinguish my frog and toad visitors and
residents by voice.
