Key identifying features
The Red-Bellied Snake (Storeria occipitomaculata) is a small, non-venomous, secretive species found across much of North America. It is easily recognized by the vivid red, orange, or salmon-colored belly that stands in sharp contrast to its plain brown or gray back, giving the species its common name.
Coloration & pattern
The dorsal color is typically brown, gray, or reddish-brown, sometimes with faint darker stripes running down the back, though many individuals appear nearly plain. A pale spot or set of small light spots is often visible just behind the head, forming a faint neck ring or collar mark. The belly, however, is the standout feature: a bright red, orange, or occasionally yellowish color that runs the length of the underside.
Head, eyes & scales
The head is small and only slightly wider than the neck, with a somewhat rounded snout. Eyes are small with round pupils. Scales are keeled (ridged), giving the back a slightly rough texture rather than a glossy sheen.
Size & body shape
Adults are quite small, typically 20–35 cm (8–14 inches) in length, with a slender, cylindrical body and a short tail. Its diminutive size is consistent across its range.
Range & habitat where you'll see it
This species is widespread across much of the eastern and central United States and southern Canada, inhabiting moist woodlands, forest edges, gardens, and areas with abundant leaf litter, logs, or rocks. It is highly secretive, most often found hidden under surface debris rather than out in the open.
How to tell it apart from look-alikes
The bright red-to-orange belly is the single most reliable identifying feature, easily distinguishing it from similarly sized brown snakes with plain or dark bellies. The faint pale neck collar and small keeled-scaled body also help confirm identification. Because it is small and generally only seen when flipped over or briefly exposed, checking the belly color is usually the quickest way to confirm this species.
