The Gray Treefrog (Hyla versicolor) and the Cope's Gray Tree Frog (Hyla chrysoscelis) are two species of tree frog found in the United States. They are almost indistinguishable and share much of the same geographic range, although the Cope's tends to be more southerly.
The only readily noticeable difference between the two species is the call. The Cope's has a faster-paced and slightly higher-pitched call. In addition, the Cope's is reported to be slightly smaller, more arboreal, and more tolerant of dry conditions than the Gray Treefrog.
Both tree frogs inhabit a wide range, and can be found in most of the eastern half of the United States, as far west as central Texas and Oklahoma. They also range into Canada in the provinces of Quebec, Ontario, and Manitoba, with an isolated population in New Brunswick.
Both tree frogs are most common in forested areas, as they are highly arboreal. Their calls are often heard in rural residential areas of the East Coast and the Midwest. They prefer to breed in semi-permanent woodland ponds without fish, but also lay eggs in swamps, vernal pools, man-made fountains and water gardens, and even in rainwater filled swimming pool covers
Both species are variable in color, mottled gray to gray-green, resembling the bark of trees. They are relatively small compared to other North American frog species, typically attaining no more than 1.5 to 2 inches (3.8 - 5.1 cm) in length measured from nose to vent. Their skin has a lumpy texture, giving them a warty appearance. The female is usually larger than the male.
Both have bright-orange patches on their hind legs, which distinguishes them from other tree frogs. The bright-yellow pattern is normally hidden, but exposed when the frog leaps. This "flash pattern" likely serves to startle a predator as the frog makes its escape. Both species are slightly sexually dimorphic. Males have black or gray throats in the breeding season, while the throats of the females are lighter.
Last but not least, both frogs are variable in color owing to their ability to camouflage themselves from gray to green, depending on the substrate where they are sitting. The degree of mottling varies. They can change from nearly black to nearly white. They change color at a slower rate than a chameleon. Dead frogs and ones in unnatural surroundings are predominantly gray.

The largest treefrog in Ohio, the gray treefrog can be any shade of brown, green, gray or black, using its camouflage to blend into its surroundings. Instead of using its coloring, it can be identified by the unchanging, dark-edged light spot beneath its eye and the bright yellow on the inside of its thighs ... a pleasant little amphibian who was handle-high on a door to my house.
Osteopilus septentrionalis found during a night walk in Vinales, Cuba. This species is considered a pest in Florida where it is introduced and prey on local species.
I was completely lying on the ground trying to focus on the frog eye. When finally I took the picture and I got up, I saw a big tarantula just a couple of meters from me…do not lie on the ground in Cuba when it’s night! :D
About 1.5 hrs. after finding the previous frog in the front yard I found this girl on the back deck. I moved her to a more photogenic surface for some shots.

Three tips to distinguish between Green and Squirrel Treefrogs: in Green Treefrogs (Hyla cinerea), a white stripe from the upper lip down the side of the body is conspicuous with clear borders but in the Squirrel Treefrog (Hyla squirella), if that line is present it is much more jagged and indistinct; the Green Treefrog often has green pigmentation below the white stripe but the Squirrel Treefrog appears to have the green stop at the white stripe; and in the green treefrog, the tympanum is usually green like the rest of the frog
To all who visit and view, and – especially – express support and satisfaction: you are much appreciated!

Album Description – Charlotte, NC – 2017SEP13 – Green Tree Frog:
An American green treefrog – my second sighting! – perched in the lilies by our front porch, this time a sunny summer late afternoon!
Found at Curtis Prairie - UW Arboretum in Madison in southern Wisconsin. Dane County, Wisconsin, USA.
Thinking probably Cope's Gray Treefrog. Confirmation appreciated.

This little guy visited my wife and I while we were having lunch on our patio on a beautiful early fall afternoon. He was really checking us out.

I'm not sure why, but I've seen very few of these guys in Central Florida, and my captures to date have been farther south in the Everglades, or farther north on the panhandle. I do however see large numbers of invasive Cuban Treefrogs in the Space Coast area, so it's possible that the more aggressive Cubans have pushed the greens out of the area.
If you look at me in the eye,
you can see I rotated this image a bit.

Yesterday morning as I was sitting on the deck with my first cup of coffee, I could hear a treefrog calling from the lily pond. I went to investigate but he quit calling. (Naturally) Every time I would go back to the deck he would fire up again so I decided to try and wait him out. I got my camera, warmed up my coffee, moved a lawn chair onto the gazebo and waited. It took a little over an hour but he finally tuned up again and I located him on the rock wall . During the time I was waiting, the sun changed positions so the the first pictures I got were in shade and he was flattened against the rock. There is one picture in the comments of him flattened ( stealth mode and shaded) and one sunlit and in full song. (click on any)
BTW I love the Beta tag on this one .....insect... ??????
