Pulchrana picturata, also known as the spotted stream frog, is a species of frog in the family Ranidae. It is endemic to Borneo (Brunei, Indonesia, and Malaysia). Pulchrana picturata (in the broad sense, including populations from the Malay Peninsula and Sumatra now assigned to Pulchrana sundabarat) is a riparian species that inhabits lowland forests where they can be found along streams or small rivers. Males are usually heard calling from stream banks, within root tangles, rock overhangs or crevices or perched on low vegetation, rocks, logs or broken branches.

Likely
About 40% of wildlife watchers report a Spotted Stream Frog sighting in Kubah National Park on a given day, based on 19 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 23rd most-seen of the 41 amphibians we can rate there. Over three days the chance rises to about 80%, and over a week to over 90%, if each day is a fresh chance.

In that month about 60% of wildlife watchers report a Spotted Stream Frog in Kubah National Park on a given day, against about 10% in April and December–February, the lowest months.
Between 7 and 10 pm
Across all the parks we cover, that three-hour window holds the most Spotted Stream Frog sightings with a recorded time, and about 9 in 10 of them come between 6 pm and 6 am: it is mostly seen at night.
Only Kubah National Park, in our data

GBIF citizen-science records
It is estimated from how often the Spotted Stream Frog is recorded against all the amphibians logged in Kubah National Park (19 verified sightings from 2019 to 2026), 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.
