About the Brown Tree Frog

Leptomantis harrissoni, common name Harrisson's flying frog or brown tree frog, is a species of frog in the family Rhacophoridae. It is endemic to northern Borneo. This species is widely distributed in northern Borneo and occurs in Sarawak and Sabah (Malaysia), Brunei, and northern Kalimantan (Indonesia).

Its natural habitat is primary or old secondary lowland rainforests in both flat and hilly terrain below 350 m of elevation. It is threatened by habitat loss. Leptomantis harrissoni can reach a length of about 50 millimetres (2.0 in) in males, of about 70 millimetres (2.8 in) in females. These medium-sized frogs have an angular and pointed snout and well developed dark hand webbing. They are basically brown.

Tadpoles can reach a length of about 40 millimetres (1.6 in), They have a well developed and rather pointed tail fin, an ovoid body and a short snout. The basic color is dark brown. Leptomantis harrissoni spends most of its life high up in the forest. Males call for breeding in water-containing holes located in the trunks of trees. Eggs are laid in a foam nest attached to the bark above said tree holes.
