The midwestern worm snake, Carphophis amoenus helenae, is a subspecies of C. amoenus, a nonvenomous, colubrid snake, endemic to the Midwest and Southern United States.[3][4]

Etymology[edit]

The subspecific name, helenae, is in honor of "Miss Helen Tennison", Robert Kennicott's cousin, who collected specimens for him in Mississippi.[5][6]

Geographic range[edit]

The subspecies ranges from southern Ohio to northern Georgia in the east and from southern Illinois to eastern Louisiana in the west.[7]

Description[edit]

Adults are small and wormlike, rarely growing longer than 9.8 in (25 cm) in total length. It is plain dark brown on top and light pink on its underside.[3]

Habitat[edit]

The midwestern worm snake is fossorial. It spends its life burrowing in moist soil or under the leaf litter searching for soft-bodied prey, with a preference for earthworms. This secretive snake prefers mesic deciduous forest.[3][4]
