The Red Eyed tree frog species was named, and quite perfectly so, by Cope in 1862 as Agalychnis callidryas. Agalychnis represents their genus and callidryas is derived from the greek words kallos, meaning beautiful, and dryas meaning tree nymph hence the ever appropriate name: the beautiful tree nymph. The Red Eyed tree frog exhibits a brilliant display of colors with it's emerald green head and back, sky blue inner legs, creamy white to yellow and bright blue striped sides, orange toes, and , of course, those piercing red eyes. Their color and size vary depending upon their geographic origination. Those originating from the northernmost ranges, such as south Mexico and Guatemala, are smallest and usually display light blue flanks and yellowish orange toes. Those originating from more southern regions, such as Nicaragua and Costa Rica, tend to be larger in size and display much more brillinat colors such as deep blue to bluish purple flanks, sky blue inner thighs, and bright orange toes. They also exhibit creamy white bellies, some will have white freckles on their dorsal surface and all have vertical pupils which are uncommon to the hylid family - all of which add to their stunning beauty.

Red Eyed tree frogs will reach an average size of 2.5 inches with a range of 2 to 3 inches in length, snout to vent. Males usually reach an average length of 2.2 inches and females are usually aroung 2.5 inches.
