With luck
About 10% of wildlife watchers report a Banded Wolf Snake sighting in Doi Inthanon National Park on a given day, based on 8 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 15th most-seen of the 30 reptiles we can rate there. Over three days the chance rises to about 40%, and over a week to about 70%, if each day is a fresh chance.
August
In that month about 40% of wildlife watchers report a Banded Wolf Snake in Doi Inthanon National Park on a given day, against under 5% in June–July, September and December–March, the lowest months. That is one of Doi Inthanon National Park's wettest months, with about 340 mm of rain against 20 mm in February.
Between 2 and 5 pm
Across all the parks we cover, that three-hour window holds the most Banded Wolf Snake sightings with a recorded time, and about 8 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
Only Doi Inthanon National Park, in our data
Doi Inthanon National Park is the only park on Wallace's Line with enough records to rate Banded Wolf Snake sightings: about 10% of wildlife watchers there report one on a given day.
Same family: Colubridae
The closest relatives of the Banded Wolf Snake that you can see in Doi Inthanon National Park (family Colubridae, Colubrid Snakes) are Oriental Whipsnake (about 20%), Banded Keelback (about 20%) and Blue-eyed Bush Rat Snake (about 20%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Banded Wolf Snake is recorded against all the reptiles logged in Doi Inthanon National Park (8 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.
