The Carolina Pigmy Rattle Snake, Sistrurus m. miliarius, is the predominant subspecies found in South Carolina. Intergrades with a more southern subspecies, Dusky Pigmy Rattlesnake, Sistrurus m. barbouri , can be found in the extreme southern portion of the State. Pigmy Rattle Snakes are sometimes called "Ground Rattlers."

These small snakes are difficult to see in their natural habitat. They are most often noticed when crossing open areas such as roads. The rattles are usually very small and difficult to see. At loudest, their rattle may sound like a buzzing insect.
