Hourglass treefrogs are small frogs, with adult females measuring 35 millimeters at their largest and adult males only 27 millimeters. Their common name comes from the hourglass shaped pattern which is usually present on the frog's back. Their arms and legs are normally boldly patterned, but their thighs are always a solid yellow color. This explains the species name ebraccata, which in Latin means "without trousers."
Subtropical or tropical moist lowland forests, subtropical or tropical moist montanes, freshwater marshes, intermittent freshwater marches, pastureland, plantations , heavily degraded former forest, and ponds.
Formerly known as Hyla ebraccata. Also known as "pantless treefrog." The hourglass treefrog reproduces in a way different to most other frogs. This frog can lay its eggs on land or in water depending on its surrounding environment. If it has shade, it will lay them on leaves of plants above the pond. If it has a lack of or only a little, it will lay them in the water, usually attached to submerged vegetation. Either way the tadpoles survive. It is the only vertebrate animal known to be capable of laying eggs both in water and on land.
