Description:H. striatula is a small, harmless, secretive, fairly slender snake, 7–10 inches in total length (including tail). It has a round pupil, weakly keeled dorsal scales, and usually a divided anal plate. Dorsally, it is brown, gray, or reddish, and essentially has no pattern. Females are a little longer and heavier than males, with relatively shorter tails. Young individuals often have a light band on the neck, which is normally lost as they mature. The belly is tan to whitish and is not sharply defined in color from the back, unlike in the wormsnake (Carphophis amoenus) or the red-bellied snake (Storeria occipitomaculata). Keeled scales differentiate the rough earth snake from the similar smooth earth snake (Virginia valeriae), as well as from the wormsnake. H. striatula is most likely to be confused with De Kay's brown snake (Storeria dekayi), which is a little larger and is light brown with dark markings on the back and neck. Unlike the rough earth snake, DeKay's brown snake retains these markings into adulthood. Also, S. dekayi has a rounder snout than H. striatula.
Habitat: The rough earth snake is fossorial, hiding beneath logs, rocks, or ornamental stones, in leaf litter, or in compost piles and gardens. The species is found in a variety of forested habitats with plenty of ground cover, as well as in many urban areas. It can reach very high densities in urban gardens, parks, and vacant lots.
Range: The rough earth snake is found from southern Virginia to northern Florida, west along the Gulf Coast to southern Texas, and north into south-central Missouri and southeastern Kansas. It is also present in northern parts of Oklahoma.
Diet:H. striatula eats invertebrates. It feeds almost exclusively on earthworms, although slugs, snails, sow bugs, insect eggs and larvae have also been found in the stomach. H. striatulais not venomous and does not constrict prey; rather, it swallows prey without subduing it. The pointed snout of the rough earth snake helps in burrowing in moist soil where prey are found.
Reproduction:H. striatula is gonochoric. It is also viviparous, giving birth to 3 to 8 live young in mid-summer. Newborns are about 4 inches in total length. The young somewhat resemble the ring-necked snake (Diadophis punctatus) with a light-colored neck collar, but they are much drabber and lack a brightly-colored belly.
Status: Listed as Least Concern in view of its wide distribution, tolerance of a degree of habitat modification, presumed large population, and because it is unlikely to be declining fast enough to qualify for listing in a more threatened category.
