The yellow-spotted keelback (Fowlea flavipunctata) is a species of colubrid snake found in Thailand, Myanmar, China, West Malaysia, Laos, Cambodia, Vietnam, and Bangladesh. Its type locality is: Island of Hong Kong (Hong Kong) and Canton River?, China.
IUCN includes Taiwan in the range of F. flavipunctata, but excludes Malaysia and Bangladesh. F. f. schnurrenbergeri of Nepal is now considered an independent species, Fowlea schnurrenbergeri. F. flavipunctata is a semiaquatic snake that occurs in slow rivers and streams, marshes, swamps, ponds, and lakes. It thrives also in wet human-modified habitats, including rice fields and ditches. It feeds on fish and frogs. It is diurnal.
F. flavipunctata is exploited in parts of its range to support snake farms and pigs and for use in snake wine.

No species of the same family or order lives in Hanoi, so these are its closest relatives here: other reptiles.
Likely
About 40% of wildlife watchers report a Yellow-Spotted Keelback sighting in Hanoi on a given day, based on 26 verified sightings from GBIF citizen-science data. It is the 4th most-seen of the 6 reptiles 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.
September
In that month about 70% of wildlife watchers report a Yellow-Spotted Keelback in Hanoi on a given day, against under 5% in April and November, the lowest months. That is one of Hanoi's wettest months, with about 220 mm of rain against 20 mm in February.
Between 1 and 4 pm
Across all the parks we cover, that three-hour window holds the most Yellow-Spotted Keelback sightings with a recorded time, and about 8 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
Yes
Of the 8 cities where we can rate Yellow-Spotted Keelback sightings, Hanoi has the highest daily chance: about 40%. Next come Xiuying District (China, about 30%) and Guangzhou (China, about 20%).
GBIF citizen-science records
It is estimated from how often the Yellow-Spotted Keelback is recorded against all the reptiles logged in Hanoi (26 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.
