Hyla chrysoscelis
Cope's Gray Treefrog
Subgenus: Dryophytes
family: Hylidae
subfamily: Hylinae
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.

From the IUCN Red List Species Account:


Range Description

This species' geographic range is not precisely determined, although it covers most of the southeastern and central USA and part of south-central Canada. It is sympatric with Hyla versicolor in south-central U.S. and in the Wisconsin area and perhaps many other areas as well. See Little et al. (1989) for information on distribution in West Virginia, southern Ohio, and southwestern Pennsylvania.

Habitat and Ecology

Habitats include wooded areas and woodland edges (including woodlots in prairies), usually within a few hundred metres of water. This species is often found in recently disturbed areas with abundant shrubs, herbaceous growth and vines. It is arboreal and terrestrial. When inactive, these frogs may hide in tree holes, under bark, under leaves, or under tree roots. In Tennessee, frogs associated with knothole cavities in trees in fall were not there after mid-November (Ritke and Babb 1991). Eggs are laid and larvae develop in temporary or permanent waters of flooded ditches, puddles, river sloughs, creeks and small ponds, where there are woody branches or extensive herbaceous growth along the edges. Males call from water surface or from vegetation or ground near water. Individuals generally breed in the same site in successive years (Ritke et al. 1991).


The total adult population size is unknown but large; the species is common in many areas. Range-wide, it is probably relatively stable.

Population Trend


Major Threats

There are no known major threats to this species.

Conservation Actions

Conservation Actions
Its range overlaps with many protected areas. No conservation measures are needed.

Red List Status

Least Concern (LC)


Listed as Least Concern in view of the large extent of occurrence, large number of sub-populations and localities, large population size and use of a wide range of habitats.

Taxonomic Notes

This species is not easily distinguished from the very similar Hyla versicolor in most published literature; it is distinguished by chromosomes, erythrocyte size (Matson 1990), and call characteristics.

The genus Dryophytes was resurrected from synonymy under Hyla by Duellman et al. (2016) and this species was transferred from Hyla to Dryophytes.
