This photo shows the two sister species of grey treefrogs. Hyla chrysoscelis is on the left and Hyla versicolor is on the right. The variation in color is common to both species, individuals of either species can range from green to grey. The difference in pupil size is an artifact of the lighting, both have similar pupil shape.
