This range map was created by attributing sub-watershed polygons with information of a species' presence, origin, seasonal and reproductive use. We therefore measured respiration rates across a range of temperatures (18.3–30°C) in wild-caught larval Cope's Gray Tree Frog (Hyla chrysoscelis), a species widespread throughout the eastern and southeastern United States. Hyla versicolor is on the left and Hyla chrysoscelis is on the right. General description: Cope's gray treefrog closely resembles the gray treefrog (H. versicolor) and can only be distinguished in the field by their call. Flickr photos, groups, and tags related to the "chrysoscelis" Flickr tag. Grant Parish, Louisiana. For Virginia, Ralin (1977) hypothesized that H. chrysoscelis occurs in the southeastern half of the state and H. Once thought to be single species, recent genetic work revealed H. chrysoscelis to be diploid and H. versicolor to be tetraploid. Species range Although smaller and slightly smoother skinned than the gray treefrog, the Cope's gray treefrog can be tough to distinguish from this close cousin, especially during the breeding season when both are usually heavily mottled on the dorsal (top) side. Compared to other North American frog species. Gray tree frogs are very small and range in size from 3.8 to 5.1 cm. The Cope's Gray Treefrogs (Hyla chrysoscelis) is sympatric (occurs in the same areas) with this species in southwestern Indiana. This range map was created by attributing sub-watershed polygons with information of a species' presence, origin, seasonal and reproductive use. protected in our region. They are found in a A detailed account of the nomenclatural and taxonomic history may be found in Johnson (1961, 1966). Their size ranges from 1-1.5 in (2.2-4.1 cm). These two species are distinguishable based on variation in their calls. when they call from vegetation surrounding wetlands. [PMC free article] Schwartz JJ, Gerhardt HC. The Cope's gray treefrog is 1�-2 inches long. They are very similar in appearance to Cope gray tree frogs (Hyla chrysoscelis). Identification: Kentucky’s two kinds of Gray Treefrogs are identical in appearance - both range to just over 2 inches long as adults and have large sticky toe pads that allow them to climb on just about any surface. also sympatric throughout much of their ranges. This dataset represents a species known range extent for Cope's Gray Treefrog (Hyla chrysoscelis) within the conterminous United States (CONUS) based on 2001 ground conditions. (1.25 - 2 in; 3.2 - 5.1 cm) with large toe pads and granular skin. Typically they have a dark “star-shaped” pattern on their back with many small warts. For species specific range information, see the attached Range data. This is the most common treefrog species in the Diagnostic leg coloration. This species of frog is very rarely seen on the ground except during the breeding season (Conant and Collins 1998). They are pretty much impossible to tell . eye and the inner thigh is bright yellow or orange to be diploid and H. versicolor to be tetraploid. Large adhesive pads on tips of fingers and toes enable them to climb vegetation. An isolated colony is also noted in New Brunswick. Geographic Range Both gray treefrog species, Hyla versicolor and Hyla chrysoscelis, are native to North America. There is usually a white or yellow spot below each eye. Elizabeth’s picture is of either a gray tree frog (Hyla versicolor) or a Cope’s tree frog (Hyla chrysoscelis). Range and Habitat: Gray Treefrogs are found throughout It can also be found in parts of Texas and Arkansas (Wright and Wright 1949). were confused under the name Hyla versicolor. They are common in much of their range near small bodies of water, and are often encountered by humans during the breeding season in spring. Two species apart by appearance, especially since both are so highly variable. The inner surface of the hind legs is yellow or orange, sometimes with black speckling. apart by appearance, especially since both are so highly variable. of SC and GA. The morphologically identical species of treefrogs,Hyla chryoscelis andH. when exposed. Because they are physically indistinguishable (see below), only their shared range has so far been fully determined. It can range in color from a mottled gray to brown, to green, depending on its environment.

Cope’s gray treefrogs, Hyla chrysoscelis, from Monona County, Iowa. i>Hyla chrysoscelis and H. versicolor , are common treefrogs in eastern North America and are a cryptic diploid-tetraploid species pair. Willson unless otherwise noted. hand washing is advised for anyone after handling gray treefrogs. In northeastern Alabama, calling can begin in late March and continue through July, but calling is most intense in April–May. These treefrogs can be found in a variety of colors, in fact, each individual frog can assume a variety of different colors (comparable to a chameleon).Their background colors range from … Temperature and body size significantly affected respiration rates in … Wright (1932) reports Hyla versicolor (almost certainly H. chrysoscelis) from the Okefenokee Swamp calling from 10 June–13 August. Summary This dataset represents a species known range extent for Cope's Gray Treefrog (Hyla chrysoscelis) within the conterminous United States (CONUS) based on 2001 ground conditions. The gray treefrog, sometimes called the Northern gray treefrog, is closely related to the Cope’s gray treefrog (Hyla chrysoscelis), with overlapping range and identical physical appearance. You can see that the H. versicolor made 7 pulses in this time (28 pulses per second) while the H. chrysoscelis made 11 pulses (44 pulses per second). be single species, recent genetic work revealed H. chrysoscelis The skin of the gray tree frog is lumpy and has a warty appearance. with which they can be confused. The gray treefrog is capable of surviving freezing of its internal body fluids to temperatures as low as -8 °C. H. versicolor has a harsher, faster call than the low, metallic call of H. chrysoscelis. Photos by J.D. Schrode KM, Buerkle NP, Brittan-Powell EF, Bee MA. There is usually a light spot beneath Ground color in the adult is gray; however, green or brown frogs may be seen, and individual frogs may show variations in color depending on conditions. Also sometimes known as Southern gray treefrog. Breeding Hyla chrysoscelis (Cope’s Gray Treefrog)is a nocturnally breeding species found throughout the eastern U.S. (Ritke et al. During the breeding season, the two species can be identified by their different calling rates. But the most noticeable difference between them is their forms of sound. Description: Gray Treefrogs are the fairly large treefrogs Interesting Facts: Hyla chrysoscelis is morphologically indistinguishable from H. versicolor and two species are also sympatric throughout much of their ranges. It tends to become darker when it is cold or dark. We therefore measured respiration rates across a range of temperatures (18.3–30°C) in wild-caught larval Cope's Gray Tree Frog (Hyla chrysoscelis), a species widespread throughout the eastern and southeastern United States.

A Cope’s gray treefrog, Hyla chrysoscelis, from Clayton County, Iowa. the Southeast except for peninsular Florida including nearly all Gray Treefrogs generally spend the day hiding in Elizabeth’s picture is of either a gray tree frog (Hyla versicolor) or a Cope’s tree frog (Hyla chrysoscelis). The two can only be distinguished by their calls. Hyla versicolor can be found in Maine, southern Canada (west to Manitoba), Minnesota, South Dakota, southern Kansas, Oklahoma, the Gulf States and northern Florida. Each of these vertical blue lines represents on pulse of the trill. The frog’s scientific name is Hyla chrysoscelis latin for “belonging to the woods” (Hyla) and golden spots (chrysoscelis) referring to the yellow or orange coloration with spots on the inside of their hind legs. Careful But the most noticeable difference between them is their forms of sound. The upper body is dark and warty. Its coloring helps it blend in with tree bark!�It has light colored spots under its eyes and bright yellow-orange on the underside of its thighs. Compared to other North American frog species. This has resulted in considerable taxonomic confusion, especially in early reports. The skin of the gray tree frog is lumpy and has a warty appearance. tree holes or other secluded areas and emerge at night to feed The diploid Hyla chrysoscelis (Cope’s Gray Treefrog) and the tetraploid H. versicolor (Gray Treefrog) ...

Conservation Status: Gray Treefrogs are common and not Account Author: Jonathan Slone, University of Georgia 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. gray to light green but their color can change depending on George R. Cline 1 Cope’s gray treefrogs (Hyla chrysoscelis) and eastern gray treefrogs (Hyla versicolor) are members of a cryptic, diploid-tetraploid species complex. It is almost indistinguishable from the gray tree frog, Hyla versicolor, and shares much of its geographic range. mucus lining of the nose, or open cuts and abrasions. They are very similar in appearance to Cope gray tree frogs (Hyla chrysoscelis). Gray Treefrogs generally breed in fishless wetlands. early summer. This dataset represents a species known range extent for Cope's Gray Treefrog (Hyla chrysoscelis) within the conterminous United States (CONUS) based on 2001 ground conditions. This range map was created by attributing sub-watershed polygons with information of a species' presence, origin, seasonal and reproductive use. Hyla avivoca - Bird-voiced Treefrog. Adult H. chrysoscelis have been used in multiple acoustic playback experiments and exhibit phonotaxis towards conspecific cues when selecting a breeding habitat (Swanson et al. Blair (1958a) plotted distinct geographic distributions of two call types across the range of what was then considered H. versicolor. Hyla chrysoscelis Cope, 1880 Cope's Gray Treefrog. The range of H. chrysoscelis in the southern United States apparently is di vided into western (central Texas) and eastern parts by the interposition ofH. Their size ranges from 1-1.5 in (2.2-4.1 cm). Safety Tip: This species of frog produces a toxic skin Green Treefrogs give a nasal "quank" call that is repeated at irregular intervals. Hyla chrysoscelis (Cope’s Gray Treefrog)is a nocturnally breeding species found throughout the eastern U.S. (Ritke et al. They vary in color from mottled Though one species tends to be more associated with the south (H. chrysoscelis) and one with the north (H. versicolor), there is considerable range overlap and the two can sometimes be found utilizing the same wetlands or even hybridizing. The bird-voiced treefrog, D. avivoca, is similar to D. chrysoscelis and D. versicolor, but is smaller (25–50 mm in length vs 32–62 mm for the gray treefrog). - edited by J.D. In those areas, D. versicolor may be present only in the Appalachians. secretion that can cause extreme discomfort to the eyes, lips, The range of D. chrysoscelis is more southerly; it is apparently the species found in the lower elevation Piedmont and Coastal Plain of Virginia and the Carolinas. trees and are most often encountered during the breeding season, on insects and small invertebrates. The known range for a species can be used to constrain the boundaries of the species distribution model and in assessments of the conservation status and/or threats within the range of a species. Adult H. chrysoscelis have been used in multiple acoustic playback experiments and exhibit phonotaxis towards conspecific cues when selecting a breeding habitat (Swanson et al. Johnson (1959, 1961, 1963, 1966) reported genetic incompatibility between the call types, prompting him to designate the faster trilling call type as H. chrysoscelis … Ouachita Parish, Louisiana.
