Recently transformed juveniles of these two frogs can be confusing because they don’t always have the same colours and markings as the adults. However, there are two characters that are reliable for both juveniles and adults if you have the frog in your hand, or can get close enough to clearly see the webbing on the hind feet.
First, bring the frog up close to your nose and smell it. Mink Frogs, when handled, release a distinctive skunky odour as a defense mechanism. If you smell this odour, you definitely have a Mink Frog. If you have a cold or sinus problems this might not help, so the second thing to do is check the hind foot webbing. In Green Frogs the 2nd and 3rd toes (counting from the left in the diagram) are unwebbed for about the last fourth of their length; in Mink Frogs these two toes are webbed right to their tips. Also, in Green Frogs the 3rd toe is a little longer than the 1st, while in Mink Frogs it is much shorter than the 1st.
