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: The species occurs in India (Assam, Arunachal Pradesh (Namdapha - Changlang district); Andaman Islands, northern parts of West Bengal), Bangladesh, Myanmar, southern Thailand, and western Malaysia (Pulau Pinang, Pahang, Pulau Tioman), possibly also in Bhutan. It is predominantly arboreal and inhabits primary and mature secondary lowland rainforest, at altitudes of up to 1,000 m.

With luck
About 10% of wildlife watchers report a Wall's Bronzeback sighting in Kuala Lumpur on a given day, based on 9 verified sightings from GBIF citizen-science data. It is the 28th most-seen of the 39 reptiles we can rate there. Over three days the chance rises to about 20%, and over a week to about 40%, if each day is a fresh chance.
May, October and December–March
In those months about 10% of wildlife watchers report a Wall's Bronzeback in Kuala Lumpur on a given day, against under 5% in April, June–September and November, the lowest months.

GBIF citizen-science records
It is estimated from how often the Wall's Bronzeback is recorded against all the reptiles logged in Kuala Lumpur (9 verified sightings), 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.
