Polypedates cruciger (commonly known as the Sri Lanka whipping frog or common hour-glass tree-frog) is a species of frog in the family Rhacophoridae endemic to Sri Lanka.

[2][3] It has been osbserved as high as 1600 meters above sea level.

[1] This frog can tolerate different habitats, including secondary forest, banana farms, gardens, and buildings.

[1] Scientists say this frog is not in danger of dying out because of its large range and tolerance to altered habitat.

[1] Scientists used to think frog was conspecific with Polypedates pseudocruciger, which lives in India's Western Ghat mountains.
