Scientific name. Haldea striatula

Common Name. Rough Earthsnake

General information. A frequently seen snake, especially after rains, Haldea striatula poses no threat to humans and is non-venomous. Preferring soft bodied prey (earthworms are the only prey known to be consumed) these snakes often seek refuge in the same places as their prey: under logs, stones, and various piles of debris. Its pointed head comes in handy and works as a spade for the snake as it searches in soft soils for earthworms.

Protected status. The Rough Earthsnake is not a protected species in Texas and can be legally collected with a hunting license.

Diagnostic features. Cone-shaped head and pointed snout. Internasal scales, generally paired in other snakes, are instead fused into a single scale Five supralabials; two small preoculars; divided anal plate; keeled dorsal scales (arranged in 17 rows near midbody).

Coloration. Adults typically have a whitish ventral surface with a grey or brown dorsal surface Dorsal color may be darker around the labial scales, as well as around the eye.

General distribution. Haldea striatula is found from central Texas eastward to the Carolinas and Virginia. They are absent from the dampest portions surrounding the Mississippi River, and range as far north as Missouri, as far south as Florida.

Texas distribution. In Texas, Haldea striatula is commonly found in the eastern third of the state.

Habitat. The Rough Earthsnake is a small earthworm-eating snake found in many backyards and open lots of eastern Texas, often found when overturning logs and stones.

Reproduction. Haldea striatula is a live bearing snake, having as many as 7 young in the late summer 7.5-12.5 cm (3-5 in). These young somewhat resemble ringneck snakes with their light colored neck collar, but this trait is lost as they become adults.

Size. Haldea striatula only reaches a length of 17.5-27.5 cm (7-11 in).

Map. Orange counties indicate new county records since previous Herps of Texas update in 1998; all other colored counties reflect known distribution prior to 1998 for species and/or subspecies. Map is based on museum voucher specimens.

Scientific name. Virginia valeriae

Common Name. Smooth Earthsnake

General information. Though not a commonly seen snake throughout much of its range, Virginia valeriae can be locally abundant in some populations. It may be much more visible after cool rains, especially in the spring as well as in the early winter prior to its retreat its winter burrows. Though earthworms are thought to be the primary prey for V. valeriae, these snakes are also known to consume snails and insects as part of their diet. To find their prey, smooth earthsnakes will typically search the moist soils under rocks and logs, using their pointed snout to root around in the soil.

Protected status. The Smooth Earthsnake is not a protected species in Texas and can be legally collected with a hunting license.

Diagnostic features. Divided anal plate; smooth dorsal scales (in 17 rows near midbody), though scales near midline may be slightly keeled. Two small postoculars, a single loreal scale, and a pair of internasals

Coloration. Dorsal color typically brown or reddish brown Ventral scales are either white or yellow-white Some individuals may have a faint light stripe along the length of the middorsal line, whereas others may have thin pigmented lines found in many of the dorsal scales, giving an illusion of having keeled scales.

General distribution. Virginia valeriae is found in portions of northeast Texas, Oklahoma and Kansas east to the Atlantic Coast from New Jersey to Florida.

Texas distribution. The single subspecies of Virginia valeriae present in Texas, V. v. elegans, is found from the Austin and San Antonio areas northeastward towards Tyler and Longview.

Habitat. The Smooth Earthsnake is an infrequently seen snake present in much of the southeastern United States, inhabiting shady and moist woodlands and adjacent bottomlands and floodplains.

Reproduction. Virginia valeriae is a live-bearing species. Litters of between 5-10 snakes, measuring 6 cm (2.5 in), are typically seen in August and September.

Size. A relatively small snake, adult Virginia valeriae measure 17.5-25 cm (7-10 in).
