Dendrelaphis cyanochloris belongs to the genus Dendrelaphis, which contains 48 other described species. D. cyanochloris is most closely related to Dendrelaphis ngansonensis, and together the two might form a species complex.
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.

Rare
Under 5% of wildlife watchers report a Wall's Bronzeback sighting in Singapore on a given day, based on 8 verified sightings from GBIF citizen-science data. It is the 57th most-seen of the 64 reptiles we can rate there. Over three days the chance rises to about 10%, and over a week to about 20%, if each day is a fresh chance.
Any time of year
In every month with enough records, under 5% of wildlife watchers report a Wall's Bronzeback in Singapore on a given day, so our monthly data shows no clear season.
Between 5 and 8 am
Across all the parks we cover, that three-hour window holds the most Wall's Bronzeback sightings with a recorded time, and about 7 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
2nd of 2
Of the 2 cities where we can rate Wall's Bronzeback sightings, Singapore ranks 2nd at under 5%. The best odds are in Kuala Lumpur (Malaysia, about 10%).
Same genus: Dendrelaphis
The closest relatives of the Wall's Bronzeback that you can see in Singapore (genus Dendrelaphis, Bronzebacks) are Common Bronze-back (about 20%), Kopstein's Bronzeback Snake (about 10%) and Gray Bronzeback (about 10%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Wall's Bronzeback is recorded against all the reptiles logged in Singapore (8 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.
