Blanford's bridle snake (Lycodon davisonii), also known commonly as Blanford's bridal snake, is a species of harmless snake in the family Colubridae. The species is endemic to Asia. Blanford's bridle snake is so named because its slim body resembles the bridle used to control horses.
L. davisonii is found in Cambodia, southern China, Laos, Myanmar, Thailand, and Vietnam. The specific name, davisonii, is in honor of British ornithologist William Ruxton Davison. The preferred natural habitat of L. davisonii is forest, at altitudes from sea level to 1,500 m (4,900 ft).
L. davisonii is terrestrial, semiarboreal, and nocturnal. L. davisonii preys upon geckos and other small vertebrates. L. davisonii is oviparous. Blanford WT (1878).

Possible
About 20% of wildlife watchers report a Blanford's Bridle Snake sighting in Cat Tien National Park on a given day, based on 10 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 30th most-seen of the 45 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 Blanford's Bridle Snake in Cat Tien National Park on a given day, against under 5% in February–March and September–December, the lowest months. That is one of Cat Tien National Park's wettest months, with about 470 mm of rain against 15 mm in February.
Between 3 and 6 pm
Across all the parks we cover, that three-hour window holds the most Blanford's Bridle 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 Cat Tien National Park, in our data
Cat Tien National Park is the only park on Wallace's Line with enough records to rate Blanford's Bridle Snake sightings: about 20% of wildlife watchers there report one on a given day.
GBIF citizen-science records
It is estimated from how often the Blanford's Bridle Snake is recorded against all the reptiles logged in Cat Tien National Park (10 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.
