Storeria Occipitomaculata – Redbelly Snake

A red-brown redbelly snake found in Missouri

Storeria occipitomaculata, the redbelly snake is a small, dark brown , grey or black snake with a red, orange or bright yellow belly. It is found in the Eastern United States and is nonvenomous.


The body of the red-bellied snake can take on a wide range of colors from dark brown to red-brown, gray or sometimes even black. Its belly is a bright orange-red. When it feels threatened, the snake turns over parts of its body to reveal the bright red warning color to scare potential predators away. Its neck is decorated with three light, often yellow spots. In the Florida redbelly subspecies, these spots are often fused together, forming a lighter-colored neck collar. The back of the head often has numerous small red dots.

Depending on the snakes coloration, it can be confused with the nonvenomous DeKay’s brown snake or the harmless ringnecked snake.

The redbelly snake is a harmless and nonvenomous snake. Due to its size, biting is not a defense mechanism for the snake when a larger predator approaches. Therefore, the snake is hesitant to bite even if handled by humans. When the snake feels threatened, it turns over to its belly to display its red warning color. In the rare cases where a redbelly snake bites a human, its causes little to no discomfort.
