AmphibiaWeb - Hyla chrysoscelis


(Translations may not be accurate.)

Hyla chrysoscelis Cope, 1880
Cope's Gray Treefrog
Subgenus: Dryophytes
family: Hylidae
subfamily: Hylinae
genus: Hyla
Taxonomic Notes: Duellman et al. (Zootaxa 2016) treated two major clades as genera; AmphibiaWeb treats these two clades as subgenera(Hyla in the Old World; Dryophytes in the New World and East Asia), thus stabilizing traditional taxonomy.

Hyla chrysoscelis is often confused with Hyla versicolor. The two species are actually identical except in distribution, call, and chromosomal count. H. chrysoscelis is diploid (N=2), where as H. versicolor is tetraploid, (N=4).

H. chrysoscelis is a relatively large treefrog that is usually gray or green in color. The exact coloration is determined by the activities and environment of individuals and can therefore vary within the species. All individuals, however, have bright orange or yellow bits of color spotted with black along their hind legs (Conant and Collins 1998).

This frog occurs widely across much of the eastern United States. They range from central Texas in the south, as far north as Ontario, Canada and all the way out to the east coast, where they can be found in the panhandle of Florida and up north into Maine (Conant and Collins 1998). H. chrysoscelis is usually found in wet woodlands, such as ponds or swamps (Bartlett and Bartlett 1999) .

Life History, Abundance, Activity, and Special Behaviors

Hyla chrysoscelis is often found in small trees or shrubs located near or in bodies of water, and are very well camouflaged against the trunks of these trees. This species of frog is very rarely seen on the ground except during the breeding season (Conant and Collins 1998).
