The gray treefrog (Dryophytes versicolor) is a species of small arboreal holarctic tree frog native to much of the eastern United States and southeastern Canada. [ 2 ] It is sometimes referred to as the eastern gray treefrog , northern gray treefrog , [ 3 ] common gray treefrog , or tetraploid gray treefrog to distinguish it from its more ...
Hyla is a genus of frogs in the tree frog family Hylidae. As traditionally defined, it was a wastebasket genus with more than 300 species found in Europe, Asia, Africa, and across the Americas. After a major revision of the family, most of these have been moved to other genera so that Hyla now only contains 17 extant (living) species from ...
Later it was placed into the genus Hyla, the true tree frogs, by Boulenger in 1882. [4] Fouquette and Dubois 2014, treated Dryophytes as a subgenus of Hyla. [4] Dryophytes was finally resurrected as an independent genus by Duellman et al. in 2016. [1] [4] [5] [6] Only geographical, rather than morphological, differences separates Dryophytes ...
The diet of Cope's gray treefrog primarily consists of insects such as moths, mites, spiders, plant lice, and harvestmen. Snails have also been observed as a food source. Like most frogs, Dryophytes chrysocelis is an opportunistic feeder and may also eat smaller frogs, including other treefrogs. [24]
One study suggested frogs select prey not by their size, but according to their activity levels, with the most active prey being the most frequently eaten. The same study showed "nearly 90% of Hyla cinerea prey were actively pursued", with the other 10% being "insects walking or close enough to be snatched up by the frog's tongue". [4]
The European tree frog (Hyla arborea) is a small tree frog.As traditionally defined, it was found throughout much of Europe, Asia and northern Africa, [3] but based on molecular genetic and other data several populations formerly included in it are now recognized as separate species (for example, H. intermedia of Italy and nearby, H. molleri of the Iberian Peninsula, H. meridionalis of parts ...
The European tree frog (Hyla arborea) is common in the middle and south of Europe, and its range extends into Asia and North Africa. North America has many species of the family Hylidae, including the gray tree frog ( Hyla versicolor ) and the American green tree frog ( H. cinerea ).
The male has a dark throat. This frog is very similar to the larger gray tree frog (Dryophytes versicolor), but that species has an orange flash on its hind legs. Both have a whitish square region just underneath the eyes. The bird-voiced tree frog is easily distinguishable during the spring and summer when it gives its characteristic call. [3 ...
