I love these little guys! When I lived up near the Dallas area I had a creek that ran behind my house. Every childhood memory I have in that house involves these guys, (and the bullfrog no one could ever catch). I do not know what they are called either. My grandfather used to call them wood frogs, (because they lived in the woods by creeks.) I now know it is certainly not a wood frog, but they are cute and teeny tiny creatures.
