Key identifying features
The Central Plains Milk Snake (Lampropeltis triangulum gentilis) is a non-venomous subspecies with the typical milk snake body plan: smooth scales, a small head not distinct from the neck, and round pupils. It is known for relatively narrow, well-defined bands compared to some other milk snake subspecies.
Coloration & pattern
This subspecies shows red or reddish-orange bands, often narrower and more numerous than in some related forms, bordered by black and separated by white or pale yellow rings. The pattern runs consistently down the length of the body, and the black snout followed by a pale band behind the head is a common identifying feature.
Head, eyes & scales
The head is small and rounded, blending smoothly into the neck. Eyes are moderate-sized with round pupils. Scales are smooth and glossy across the body, giving the bands a clean, polished look in good lighting.
Size & body shape
Adults typically reach 50–80 cm (20–31 inches), with a slender, cylindrical body and a moderately long tapering tail. Juveniles display the same tricolor pattern as adults, sometimes with slightly brighter coloration at hatching.
Range & habitat where you'll see it
This subspecies is found across the central Great Plains, including parts of Nebraska, Kansas, Colorado, and neighboring states, favoring prairie grasslands, sandy or rocky soils, and agricultural edges. It is secretive and largely nocturnal, often found under rocks, boards, or in loose soil burrows.
How to tell it apart from look-alikes
Compared to other milk snake subspecies, this form tends to have narrower, more numerous bands rather than broad saddles. As with all North American milk snakes, red bands border black bands rather than yellow, distinguishing it from any venomous coral snakes found farther south. Smooth scales and round pupils separate it from prairie rattlesnakes and other pit vipers sharing its grassland range, which have keeled scales and vertical pupils.

Across the central Great Plains, including Nebraska, Kansas, and Colorado, in prairie grassland and rocky habitats.
How do I tell it apart from a coral snake?
