The Hourglass Tree Frog receives its name from the dark brown mark on its back, which resembles an hourglass due to its shape. Overall, it is colored orange and brown, with small light spots on darker areas and small dark spots on the lighter zones. Some individuals are rather pattern less and look entirely orange. It is common and widespread in both caribbean and pacific lowlands. This species is arboreal and nocturnal, and can be found in disturbed areas, including gardens close to people’s homes. It is not likely to be confused with any other frog species that inhabit Costa Rica, although the other two species in the Dendropsophus genus have a similar orange color, but without the intricate patterns of the Hourglass.

This male was clinging to the leaf with much force. The sticky nature of frogs’ fingers and toes is inspiring research into new technologies and adhesive materials.
This male was very active during the photoshoot. It would jump out of view before I could even focus properly, so I ended up with many out of focus images. Taken under a controlled environment.
Another shot of the Hourglass Frog. This is a male, which is noticeably smaller than the female. Like many other frogs, it clings on top of the female to stimulate her to release her eggs, which he then fertilizes in the water.
Although not visible on this angle, it has a brown hourglass shaped mark on the back, which gives its name to this species. They are tiny but brilliantly colored.
