Hong Kong Whipping Frog – Hong Kong Wildlife | 斑腿泛樹蛙 – 香港野生動物

Hong Kong whipping frog (Polypedates megacephalus), also called Spot-legged tree frog, is a species in the shrub frog family (Rhacophoridae). In Hong Kong, it is more commonly known as “Brown tree frog”. But this name is otherwise applied to a few other species of frogs such as Litoria ewingii and Litoria littlejohni of Australia in family Pelodryadidae, and Ecnomiohyla miliaria of Central America in the true tree frog family (Hylidae).

It is widely spread throughout Hong Kong including all major islands. This species is also native to central, southern and southwestern China (including Taiwan and Hainan) and Indo-China peninsula.

An ‘X’-shaped marking can be seen on some of the frogs’ back. Males grow to 5 – 6 cm. Females are bigger, can grow to up to 8 cm. The breeding season is from April to September. Females lay eggs in a white foam nest on tree trunks, bushes, or rocks near water. The nests separate tadpoles from water.

When threatened they can secrete a fluid that may be toxic or unpalatable to potential predators.
