Hourglass treefrog

Dendropsophus ebraccatus

''Dendropsophus ebraccatus'', commonly known as the hourglass treefrog or pantless treefrog, is a species of frog in the Hylidae family.
It is found in Belize, Colombia, Costa Rica, Ecuador, Guatemala, Honduras, Mexico, Nicaragua, and Panama.

Its natural habitats are subtropical or tropical moist lowland forests, subtropical or tropical moist montane forests, freshwater marshes, intermittent freshwater marshes, pastureland, plantations, heavily degraded former forest, and ponds.

The hourglass treefrog reproduces differently from most other frogs. It can lay its eggs on land or in water, depending on the environment. If it has shade, it will lay them on leaves of plants above the pond. If it has little or no shade, it will lay them in the water, usually attached to submerged vegetation. It is the only vertebrate known to be capable of this. Like many frog species within the Hylidae, the tadpoles of ''D. ebraccatus'' show predator-induced plasticity in their tail colour when exposed to dragonfly nymphs.
