Key identifying features
The Ecuadorian Milk Snake (Lampropeltis triangulum micropholis, in part) is a non-venomous colubrid displaying the classic milk snake tricolor pattern. It has smooth scales, a small head barely wider than the neck, and round pupils, distinguishing it at a glance from venomous species.
Coloration & pattern
This population typically shows red or reddish-orange bands bordered by black, alternating with narrower white or cream rings that fully encircle the body. Band width and exact color intensity can vary somewhat between individuals, but the overall tricolor sequence remains consistent. The snout is usually black, transitioning to a pale band just behind the head.
Head, eyes & scales
The head is small, rounded, and not distinctly wider than the neck. Eyes are moderate in size with round pupils, a helpful non-venomous indicator. Scales are smooth across the body, producing a glossy, polished look that helps separate it from rough-scaled or keeled venomous species.
Size & body shape
Adults commonly reach 60–90 cm (24–35 inches) in length, with a slim, cylindrical body and a moderately long, tapering tail. Juveniles hatch with the same banded pattern seen in adults, sometimes appearing slightly brighter before subtle fading with age.
Range & habitat where you'll see it
This milk snake is native to lowland and foothill regions of Ecuador, including parts of the Amazon basin edge and Pacific lowlands, occupying tropical forest, forest edge, and agricultural clearings. It is largely secretive, most active after dark, and often found beneath leaf litter, logs, or debris.
How to tell it apart from look-alikes
As with other milk snakes, the defining separation from venomous coral snakes sharing its range is that red bands are bordered by black rather than yellow. Compared to other regional milk snake subspecies, subtle variation in band proportions and locality are the main distinguishing clues. Round pupils, smooth scales, and a small non-triangular head confirm its non-venomous identity when compared to any pit vipers in the same habitat.
Frequently asked questions
Is the Ecuadorian Milk Snake venomous?
No, it is a non-venomous constrictor despite its coral-snake-like coloring.
What is the easiest way to tell it apart from a coral snake?
On this milk snake, red bands touch black bands, while true coral snakes have red bands touching yellow bands.
Where does it live?
In lowland and foothill tropical forest and forest-edge habitats of Ecuador.
What do the scales look like?
Smooth and glossy, unlike the keeled scales found on venomous vipers.
Do juveniles look different from adults?
Juveniles show the same tricolor banding as adults, sometimes with slightly brighter coloration.
