|Scientific Name:||Dryophytes versicolor (LeConte, 1825)|
Hyla versicolor LeConte, 1825
|Taxonomic Source(s):||Duellman, W.E, Marion, A.B. and Hedges, S.B. 2016. Phylogenetics, classification, and biogeography of the treefrogs (Amphibia: Anura: Arboranae). Zootaxa 4104: 1-109.|
|Taxonomic Notes:||This species is not distinguished from the very similar Hyla chrysoscelis 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.
|Red List Category & Criteria:||Least Concern ver 3.1|
|Assessor(s):||IUCN SSC Amphibian Specialist Group|
|Contributor(s):||Hammerson, G.A. & Pelletier, S.|
|Facilitator/Compiler(s):||Angulo, A. & Sharp, D.|
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.
|Previously published Red List assessments:|
|Range Description:||This species' geographic range is not precisely determined, although it covers much of the eastern USA and southeastern Canada. It is sympatric with Hyla chrysoscelis in Wisconsin, south-central U.S., and probably many other areas. See Little et al. (1989) for distribution in West Virginia, southern Ohio, and southwestern Pennsylvania. See McAlpine et al. (1991) for information on distribution in eastern Maine and southwestern New Brunswick.|
Native:Canada (Manitoba, New Brunswick, Ontario, Québec); United States (Arkansas, Connecticut, Delaware, Illinois, Indiana, Iowa, Kansas, Kentucky, Louisiana, Maine, Maryland, Massachusetts, Michigan, Minnesota, Missouri, New Hampshire, New Jersey, New York, North Carolina, Ohio, Oklahoma, Pennsylvania, Rhode Island, Tennessee, Texas, Virginia, West Virginia, Wisconsin)

|Population:||The total adult population size is unknown but large and probably stable.|
|Current Population Trend:||Stable|
|Habitat and Ecology:||This species occurs in various kinds of wooded and forested habitats. It is both arboreal and terrestrial. It hides in tree holes, under bark, in rotten logs, under leaves and under tree roots when inactive. Eggs and larvae develop in shallow woodland ponds and marshes, puddles, ponds in forest clearings, swamps, bogs and many other kinds of permanent or temporary waters lacking a significant current, including ponds created through excavation by humans. In northern Minnesota, successful reproduction in acidic bog water either does not occur or is a rare event (Karns 1992). In central Ontario, embryos and larvae exhibited a high degree of acid tolerance (J. Herpetol. 26:1-6).|
|Use and Trade:||
It is found in the pet trade, but this does not constitute a significant threat.
|Major Threat(s):||No major threats are known. Introduced Bluegill Sunfish might cause declines in larval tree frog abundance (Smith et al. 1999), and it is found in the pet trade.|
This species occurs in many protected areas. No conservation measures are needed.
|Amended reason:||This amended assessment has been created because the species was transferred from the genus Hyla to Dryophytes.|
