Key identifying features
Dekay's brownsnake (Storeria dekayi) is a small, secretive colubrid widespread across much of North America, identified by a light tan to grayish-brown body with a pale dorsal stripe flanked by two rows of small dark spots, giving it a subtly patterned, understated appearance.
Coloration & pattern
Ground color is typically light brown, tan, or grayish, with a faint pale central stripe running down the back, bordered on each side by a row of small, dark brown or blackish spots, sometimes connected by short crossbars in a ladder-like arrangement. A dark spot or mark is often present just behind the head, sometimes described as a paired neck blotch. The belly is pale pinkish or cream, generally unmarked.
Head, eyes & scales
The head is small and only slightly distinct from the neck, with moderate-sized eyes and round pupils. Dorsal scales are keeled, giving the body a slightly rough texture. The subtle head markings and small size make close observation useful for confirming identification.
Size & body shape
This is a small species, typically 20 to 33 centimeters in length, with a slender to modestly stout body and a short tail relative to overall length. Its small size and secretive habits mean it is often overlooked despite being common.
Range & habitat where you'll see it
Dekay's brownsnake is found across a broad swath of the eastern, central, and parts of the southern United States, extending into southeastern Canada and Mexico, favoring woodland edges, gardens, vacant lots, and areas with abundant cover such as logs, rocks, and leaf litter, including urban and suburban settings. It is primarily nocturnal or crepuscular, feeding largely on earthworms and slugs.
How to tell it apart from look-alikes
The pale central stripe bordered by small dark spots, combined with keeled scales and small overall size, helps distinguish this species from similarly small snakes such as the ring-necked snake, which has a solid dark back and a distinct pale neck ring, or juvenile gartersnakes, which typically show bolder, more contrasting longitudinal stripes. Its subdued brown tones and secretive, ground-dwelling habits under cover objects are also useful identification clues.
