Hi Jo,
That's a good question about the spot. All of the pictures I have seen of southern leopard frogs have a very noticeable white spot in the tympanum. I am not sure if the spot develops with age or not. You are right about NLFs being endangered in B.C. I really love leopard frogs, there are plenty in Nebraska and I hear them call throughout the spring and early summer. Anyway, you have a very handsome frog indeed.![]()
