Rhacophorus nigropalmatus

This species is arboreal, spending most of its life in the trees. It is known for its remarkable gliding ability, which it uses to escape predators and move between trees. Wallace's Flying Frog is nocturnal and feeds primarily on insects and other small invertebrates.

Breeding takes place during the rainy season when males call to attract females to small temporary ponds created by the rain. The female lays eggs on overhanging vegetation, and the developing tadpoles eventually drop into the water below where they complete their development.

Wallace's Flying Frogs are medium-sized, typically about 3 to 4 inches in length. Their standout features are the oversized webbed feet and a flap of skin that stretches between their limbs, allowing them to glide distances of up to 50 feet (15 meters) or more.

The frog is named after Alfred Russel Wallace, a British naturalist who co-developed the theory of natural selection. Wallace was among the first to document the gliding behavior of these frogs during his extensive travels through the Malay Archipelago in the 19th century.

Wallace's Flying Frog is not currently listed as endangered, but it faces threats from habitat destruction and degradation, primarily due to deforestation for agriculture and urban development in Southeast Asia. Conservation efforts are important to preserve the rainforest habitat essential for the survival of this and many other species.
