Key identifying features
The Utah milk snake (Lampropeltis triangulum taylori) is a nonvenomous kingsnake subspecies notable for its bold tricolor banding of red, black, and white or pale yellow encircling the body, a pattern often compared to venomous coral snakes though the two are not closely related and easily distinguished by band arrangement and range. It has smooth, glossy scales and a slender, cylindrical body.
Coloration & pattern
The body displays alternating bands of red, black, and white or pale yellow running around the entire circumference, with the red bands often the widest and bordered on each side by narrower black bands, which are in turn bordered by white or pale bands. The snout is typically black, and the pattern is consistent and bold along the whole body length.
Head, eyes & scales
The head is narrow and only slightly distinct from the neck, typical of kingsnakes, with round pupils and smooth, glossy body scales that give the snake a sleek appearance. The relatively small head and round pupils are useful features distinguishing it from unrelated venomous species with more triangular heads.
Size & body shape
Adults typically reach 40–90 cm, with a slender, smooth-scaled cylindrical body and a moderately long tail, consistent with the milk snake's build across its many subspecies.
Range & habitat where you'll see it
The Utah milk snake is found in the desert and semi-arid regions of Utah and adjacent parts of the southwestern United States, favoring rocky slopes, canyons, and desert scrub, often found under rocks or debris in these habitats.
How to tell it apart from look-alikes
The key distinction from venomous coral snakes in regions where ranges might be confused relates to band order: in milk snakes, black bands directly border red bands, whereas in coral snakes yellow bands separate red from black. The Utah milk snake's round pupils, smooth scales, and narrow head also distinguish it from unrelated rattlesnakes or other pit vipers, which have vertical pupils, keeled scales, and broad triangular heads.

It shows bold bands of red, black, and white or pale yellow encircling the entire body, with a black snout.
How big does the Utah milk snake get?
Adults typically reach 40–90 cm in length with a slender, smooth-scaled body.
Where is the Utah milk snake found?
It occurs in desert and semi-arid regions of Utah and nearby parts of the southwestern United States, in rocky and scrub habitats.
