How to Identify Slowinski's Corn Snake (Identification Guide)

Key identifying features

Slowinski's Corn Snake is a medium-sized constrictor, generally 3 to 4.5 feet long, with a series of large, dark-bordered reddish-brown to orange blotches running down a tan to gray-brown background. It closely resembles the more widely known corn snake in overall appearance, as the two were only relatively recently recognized as genetically distinct.

Coloration & pattern

The body has a row of squarish or rounded dorsal blotches, each outlined in black, spaced evenly along the length of the snake. The ground color tends to be a duller tan, gray-brown, or olive compared to the brighter orange background typical of the classic eastern corn snake, and the blotches themselves are often a more muted brownish-red rather than vivid orange-red. Smaller blotches alternate along the sides. The belly typically shows a black-and-white checkerboard pattern.

Head, eyes & scales

The head bears a spear-shaped or arrow-like marking between the eyes, a trait shared with other corn snake species, along with large round pupils. Scales are weakly keeled and the head is only slightly wider than the neck, giving a fairly streamlined profile.

Size & body shape

The body is slender and moderately long, well adapted for climbing and moving through loose soil and leaf litter. Juveniles show the same blotched pattern as adults but often appear more strongly contrasted, with the blotches slightly brighter relative to a darker ground color at hatching.

Range & habitat where you'll see it

This species occupies parts of the south-central United States, generally west of the Mississippi River, including areas of Texas, Oklahoma, and neighboring states, occupying prairies, open woodlands, and agricultural edges. It often shelters under debris, in rodent burrows, and around old buildings.

How to tell it apart from look-alikes

Slowinski's Corn Snake is extremely similar in appearance to the eastern corn snake and is best distinguished by its range, as the two occupy largely separate geographic areas with limited overlap; the eastern corn snake occurs generally east of the Mississippi, and this species west of it. Compared to the more muted, brownish tones of this species, the classic corn snake tends to show brighter orange-red blotches on a more saturated orange background, though this distinction can be subtle and variable. It can be told apart from copperheads by its more elongated blotch pattern along the back versus the copperhead's hourglass-shaped crossbands, and by its slender build and round pupils.
