Yucatan casque-headed tree frog (Tiprion petasatus)
Uxmal, Yucatan, Mexico

I found this frog at around 6:00 pm. It was already dark. It was located in the wall, outside of its little hiding spot, right next to a banana tree. It's the first time I've ever seen one of this in real life, but I did know they usually hang around banana and lime trees :)
