The green treefrog has round adhesive pads on all digits. This frog’s coloration is normally bright, light green, but in cool weather it may be dark green. There is always a white or pale yellow stripe running from the upper lip down along the sides. Some yellow spots may also be present on the back. The belly is white or yellowish. Call is a measured, nasal “quank, quank, quank” series, normally not heard until after sundown. The call is a noticeable part of the nighttime sounds of our cypress swamps.
Similar species: Missouri has two other treefrog species, both of which are quite similar to one another: the gray treefrog (H. versicolor) and Cope’s gray treefrog (H. chrysoscelis). Unlike the green treefrog, these are both gray and, counted together, are found statewide.
