Hourglass Treefrog, Costa RicaDendropsophus ebraccatus is the proper name, but this guy is more commonly known as the hourglass treefrog due to the pattern on his back (which you can’t quite see in this photo). But as is usually the case, there’s yet another name — the pantless treefrog. Ebraccata means “without trousers” in Latin and it refers to the fact that there are bold patterns on the bottoms of the legs which are absent on the upper legs, ergo, no pants. So now you know. Nikon D700 with Nikkor 105mm macro lens, ISO 400, f/14 at 1/60th of a second, two Nikon SB-900 flash units.
