Lycodon laoensis, commonly known as the Laotian wolf snake, is a species of non-venomous colubrid snake endemic to Asia. It is found in India, Thailand, Laos, Vietnam, Cambodia, China (Yunnan), West Malaysia and Myanmar.
Dorsally it is dark brown, with a whitish or yellowish crossband on the occiput, and similar body crossbands which bifurcate on the sides. Ventrally it is whitish. Adults are about.5 m (20 inches) in total length, which includes the tail of about 10 cm (4 inches).
They are nocturnal, and generally ground dwelling. They are not very aggressive and generally reluctant to bite. Like other Wolf Snakes, they can be mistaken for the venomous Banded Kraits. Aung, S.

Possible
About 20% of wildlife watchers report a Laotian Wolf Snake sighting in Khao Sok National Park on a given day, based on 9 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 27th most-seen of the 44 reptiles we can rate there. Over three days the chance rises to about 50%, and over a week to about 80%, if each day is a fresh chance.
February, May and August
In those months about 30% of wildlife watchers report a Laotian Wolf Snake in Khao Sok National Park on a given day, against under 5% in March–April, June, September and December, the lowest months.
Between 2 and 5 pm
Across all the parks we cover, that three-hour window holds the most Laotian 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.
2nd of 2
Of the 2 parks where we can rate Laotian Wolf Snake sightings, Khao Sok National Park ranks 2nd at about 20%. The best odds are in Cat Tien National Park (Vietnam, about 30%).
GBIF citizen-science records
It is estimated from how often the Laotian Wolf Snake is recorded against all the reptiles logged in Khao Sok National Park (9 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.
