The royal ground snake (Erythrolamprus reginae) is a species of snake in the family Colubridae. The species is endemic to northern South America. Erythrolamprus reginae belongs to the genus Erythrolamprus, which contains over 50 species. The genus Erythrolamprus belongs to the subfamily Dipsadinae, which is sometimes referred to as the family Dipsadidae.
Recent phylogenetic analysis of morphological and molecular DNA evidence has shown that Erythrolamprus reginae is now likely paraphyletic. Erythrolamprus zweifeli was previously considered to be a subspecies of Erythrolamprus reginae and called Erythrolamprus reginae zweifeli. However, based on notable differences in coloration and scale counts, it is now considered to be a separate species. Erythrolamprus pseudoreginae of Tobago, named in 2019, was also previously considered to be part of Erythrolamprus reginae, but is now separate.
The relationships of Erythrolamprus species located in northern South America can be shown in the cladogram below: It feeds on frogs, frog eggs, tadpoles, fish, small birds, and lizards. In an experiment conducted by biologists from the University of California... Wikipedia →

Possible
About 20% of wildlife watchers report a Royal Ground Snake sighting in Tambopata National Reserve on a given day, based on 17 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 18th most-seen of the 47 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.
March, June and December
In those months about 30% of wildlife watchers report a Royal Ground Snake in Tambopata National Reserve on a given day, against under 5% in April–May, August and October, the lowest months.
Between 8 and 11 am
Across all the parks we cover, that three-hour window holds the most Royal Ground 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.
Yes
Of the 2 parks where we can rate Royal Ground Snake sightings, Tambopata National Reserve has the highest daily chance: about 20%. Next come Manu National Park (Peru, about 10%).
GBIF citizen-science records
It is estimated from how often the Royal Ground Snake is recorded against all the reptiles logged in Tambopata National Reserve (17 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.
