Description:
Harmless. Shiny, glossy smooth scales. Body uniform dark gray to brown above; pink or coral belly, color extends up onto sides of the body. Head is flattened to aid in moving through loose earth. Young same as adults, but belly may be more intense pink. Western worm snakes have a dark, black or brownish dorsal coloration, with a pink or reddish underside.
Adults normally grow 190-280 mm (7½-11 inches) in TL; largest specimen from Kansas: female (KU 206169) from Doniphan County with TL of 366 mm (14 3/8 inches) collected by Robert Powell on 2 May 1986; maximum length throughout range: 15 3/8 inches (Conant and Collins, 1998); maximum weight for Kansas specimen: 14.5 grams(½ ounce).

Distribution:
Found in the more heavily forested eastern third of Kansas. This species favors more heavily forested areas and makes it into the Flint Hills along riparian corridors.

Natural History:
Found under rocks, on rocky wooded hillsides, and along the forest edge. Active from March to November; breeds in spring and lays up to 5 eggs that hatch in August. Eats earthworms. Very secretive; generally can only be found under rocks during April; spends rest of year beneath the ground. Never bites.
Little is known about their mating habits, but breeding likely occurs in the early spring and eggs are laid in the early summer. Clutch size is normally 1-8 eggs and hatching takes place in August or September. Hatchlings range in size from 3 to 4 inches (7 to 10 cm).

Occurrence Activity:
White dates indicate there is at least a single recorded occurrence on that date. The darker blue a date is, the greater the relative number of observations for that date.
Remarks:
Burth and Hoyle (1935) reported on a Western Wormsnake collected under stones on a grassy hillside near a spring not far from Spring River and about 3 miles north of Baxter Springs, Cherokee County, Kansas, by Edward H. Taylor and Hobart M. Smith on 4 April 1931.
