Comments: HARMLESS (Non-Venomous). The Rough Earth Snake feeds almost exclusively on earthworms, although ant larvae may also be consumed. Its pointed snout facilitates burrowing in the moist soil where its prey is found. Can be found under flat debris such as boards and old sheet metal roofing. The rough earth snake bears live young. Litters of 3-8 young are born in summer. They are 3-4.5 inches (7.6-11 cm) at birth.

Comparison with other species: The Eastern Smooth Earth Snake (Virginia valeriae) has smooth scales and a less pointed snout. The Pine Woods Snake (Rhadinaea flavilata) has smooth scales and a whitish upper lip. The Ringneck Snake (Diadophis punctatus) has smooth scales and is grayish-black with a distinct neck ring and a yellow-orange belly. Dekay's Brown Snake (Storeria dekayi) have spots or flecking on the back and sides.
