About the Redbelly Snake

Storeria occipitomaculata, commonly known as the redbelly snake or the red-bellied snake, is a species of harmless snake in the subfamily Natricinae of the family Colubridae. The species is native to North America (Canada and the United States).

Storeria occipitomaculata is a small woodland species that usually measures 4–10 in (10–25 cm) in total length (including tail). Its dorsal color ranges from orange to gray, black, or brown. It can be distinguished from other species by its bright red or orange underbelly. Many individuals have a light brown ring behind the head.

Storeria occipitomaculata prefers warmer habitats, and in the more northern limits of its range will inhabit abandoned ant mounds. These mounds absorb solar radiation and are insulated which allows for a longer active season. This species, with large eyes and a kinetic skull, is not able to burrow on its own effectively, and abandoned ant mounds allow it access to a warm retreat. Individuals of this species can be found under logs and leafy debris due to its secretive nature.
