DistributionRead full entry
Both gray treefrog species, Hyla versicolor and Hyla chrysoscelis, inhabit a wide range from southern Ontario and Maine, westward to central Texas, northwest to Manitoba, and northern Florida. An isolated colony is also noted in New Brunswick. The two species appear physically identical, and consequently more studies are necessary to delineate where the species overlap.
Generally, the eastern gray treefrog (H. versicolor) is mostly found to the north and northeast of the range. However, the gray treefrog species are extremely variable in their distribution pattern. For instance, the eastern gray treefrog is common in the eastern Great Lakes region, including southern Michigan; however, both species: H. versicolor and H. chrysoscelis share the same breeding ponds in Wisconsin and northern Michigan.
