Agalychnis callidryas
The red-eyed tree frog’s scientific name is Agalychnis callidryas. Agalychnis comes from the Greek words aga, which means “plenty of,” and lychnos, which means “shining.” This reflects the frog’s abundance of brilliant colors. Callidryas comes from the Greek word for “beautiful,” which is kallos, and the Greek word for “tree nymph,” which is dryas. There is only one species of Agalychnis callidryas and no subspecies.
