Dendrelaphis kopsteini, also known commonly as Kopstein's bronzeback snake, is a species of snake in the subfamily Ahaetuliinae of the family Colubridae. The species is native to Southeast Asia. The specific name, kopsteini, is in honor of Felix Kopstein, who was an Austrian physician and naturalist, and did field work in the Dutch East Indies.
D. kopsteini is the only species in its genus with red coloration on the anterior part of the body. The dorsal scales are arranged in 15 rows at midbody. The ventrals number 167–181, and the subcaudals number 140–154. D. kopsteini is found in Brunei, Indonesia, Peninsular Malaysia, Singapore, and Thailand.
The preferred natural habitat of D. kopsteini is forest, at altitudes from sea level to 624 m (2,047 ft), but it has also been found in artificial habitats such as village gardens. D. kopsteini is arboreal and diurnal. D. kopsteini preys predominately upon lizards, and to a lesser extent upon frogs.

With luck
About 10% of wildlife watchers report a Kopstein's Bronzeback Snake sighting in Singapore on a given day, based on 148 verified sightings from GBIF citizen-science data. It is the 21st most-seen of the 64 reptiles we can rate there. Over three days the chance rises to about 30%, and over a week to about 50%, if each day is a fresh chance.
Any time of year
In every month with enough records, about 10% of wildlife watchers report a Kopstein's Bronzeback Snake in Singapore on a given day, so our monthly data shows no clear season.
Between 10 am and 1 pm
Across all the parks we cover, that three-hour window holds the most Kopstein's Bronzeback 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 Singapore, in our data
Singapore is the only city on Wallace's Line with enough records to rate Kopstein's Bronzeback Snake sightings: about 10% of wildlife watchers there report one on a given day.
Same genus: Dendrelaphis
The closest relatives of the Kopstein's Bronzeback Snake that you can see in Singapore (genus Dendrelaphis, Bronzebacks) are Common Bronze-back (about 20%) 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 Kopstein's Bronzeback Snake is recorded against all the reptiles logged in Singapore (148 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.
