Polypedates megacephalus, the Hong Kong whipping frog or spot-legged tree frog, is a species in the shrub frog family (Rhacophoridae). In its native range, it is also called "brown tree frog", but this name is otherwise applied to a species of the true tree frog family (Hylidae).
This species is native in central, southern and southwestern China (including Hong Kong and Hainan) and Indo-China peninsula. It is closely related to Polypedates leucomystax and was formerly included in P. leucomystex species complex, along with P. mutus and P. braueri.
Previously, P. megacephalus was thought to distribute above the Red River of Vietnam and in Northeast India, while P. leucomystex was generally found south of the Red River and in western Yunnan. However, recent genetic studies revealed that the natural barriers between these species are the Isthmus of Kra and the Tenasserim Range, where P. megacephalus can be found above the isthmus and east of the range.
This frog is listed as Least Concern in view of its wide distribution in Asia and its tolerance of a broad range of habitats. It also because of its presumed large population. This species is... Wikipedia →

Possible
About 30% of wildlife watchers report a Spot-legged Tree Frog sighting in Hanoi on a given day, based on 17 verified sightings from GBIF citizen-science data. Over three days the chance rises to about 70%, and over a week to about 90%, if each day is a fresh chance.
March, July, September and November–December
In those months about 40% of wildlife watchers report a Spot-legged Tree Frog in Hanoi on a given day, against under 5% in January–February, May–June, August and October, the lowest months.
Between 1 and 4 pm
Across all the parks we cover, that three-hour window holds the most Spot-legged Tree Frog sightings with a recorded time, and about 9 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
5th of 12
Of the 12 cities where we can rate Spot-legged Tree Frog sightings, Hanoi ranks 5th at about 30%. The best odds are in Cần Thơ (Vietnam, about 60%), Ho Chi Minh City (Vietnam, about 40%) and Yangon (Myanmar, about 40%).
Same order: Anura
The closest relatives of the Spot-legged Tree Frog that you can see in Hanoi (order Anura, Frogs and Toads) are Common Indian Toad (about 40%), Asian Painted Frog (about 30%) and Asian Peters Frog (about 20%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Spot-legged Tree Frog is recorded against all the amphibians logged in Hanoi (17 verified sightings), calibrated against known sighting rates. Figures are rounded to the nearest 10% because citizen-science data supports honest approximations, not decimals, and months with records from fewer than five people show "—". How it works.
