hello

[Kurt]

Kurt's frog is a Green Tree Frog (Hyla cinerea) and is native to the U.S. His just happens to be slightly different, you'll see some GTFs with yellow spots, some that are albino, and even some that are blue. You're probably talking about Red Eyed Tree Frogs (Agalychnis callidryas). They do change from lime green to dark green quite often and as the name suggests they have bright red eyes.

I could've said any better myself. And I have both a GTF and 4 red-eyed leaf frogs some of which are posted in my profile.

BTW if you look in the Peterson field guide for the Eastern US, they show both colour morphs of Hyla cinerea in one of the color plates.
