Dendrelaphis caudolineatus, commonly known as the striped bronzeback or grey bronzeback, is a species of colubrid snake found in Southeast Asia.

However, in Latin "cauda" means tail and "linea" mean line, possibly referencing the longitudinal lines reaching from head to tail.
Dendrelaphis caudolineatus belongs to the genus Dendrelaphis, which contains 48 other described species. Prior to a 2012 study, several other species of Dendrelaphis were previously considered to be members of Dendrelaphis caudolineatus, but are now considered to be separate species: D. flavescens, D. terrificus, D. philippinensis, and D. levitoni.
Dendrelaphis is one of five genera belonging to the vine snake subfamily Ahaetuliinae, of which Dendrelaphis is most closely related to Chrysopelea, as shown in the cladogram below: Dendrelaphis caudolineatus is found in Malaysia, Thailand, Indonesia, Brunei, and Singapore. It is found in a wide variety of forested habitats, commonly seen in trees and bushes, most... Wikipedia →

With luck
About 10% of wildlife watchers report a Gray Bronzeback sighting in Khao Sok National Park on a given day, based on 6 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 36th most-seen of the 44 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.

GBIF citizen-science records
It is estimated from how often the Gray Bronzeback is recorded against all the reptiles logged in Khao Sok National Park (6 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.
