The banded krait (Bungarus fasciatus) is a venomous species of elapid endemic to Asia, from Indian subcontinent through Southeast Asia to Southern China. With a maximum length exceeding 2 m (6 ft 7 in), it is the longest krait with a distinguishable gold and black pattern. While this species is generally considered timid and docile, resembling other members of the genus, its venom is highly neurotoxic which is lethal to humans. Although toxicity of the banded krait based upon murine LD50 experiments is lower than that of many other kraits, its venom yield is the highest due to its size.
The banded krait is easily identified by its alternate black and yellow crossbands all of which encircle the body. The head is broad and depressed and it is not distinct from the neck. The eyes are black. It has arrowhead-like yellow markings on its otherwise black head and has yellow lips, lores, chin, and throat. The tail is relatively small, about one-tenth the length of the snake.
The longest banded krait measured was 2.25 m (7 ft 5 in) long, but normally the length encountered is 1.8 m (5 ft 11 in). Scalation: 15 dorsal scale rows at midbody; sub-caudal scutes undivided throughout... Wikipedia →

With luck
About 10% of wildlife watchers report a Banded Krait sighting in Khao Yai National Park on a given day, based on 8 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 32nd most-seen of the 46 reptiles we can rate there. Over three days the chance rises to about 30%, and over a week to about 60%, if each day is a fresh chance.
February, June, September and November
In those months about 20% of wildlife watchers report a Banded Krait in Khao Yai National Park on a given day, against under 5% in April–May, July–August, October and December–January, the lowest months.
Between 2 and 5 pm
Across all the parks we cover, that three-hour window holds the most Banded Krait 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 Banded Krait sightings, Khao Yai National Park ranks 2nd at about 10%. The best odds are in Cat Tien National Park (Vietnam, about 30%).
GBIF citizen-science records
It is estimated from how often the Banded Krait is recorded against all the reptiles logged in Khao Yai 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.
