There are two recognized subspecies of M. schotti found in Texas, although one subspecies' (Masticophis schotti ruthveni) limited range in Texas is said to broadly overlap that of the other (M. s. schotti).
With bodies often not much thicker than a person's index finger, Masticophis schotti adults are typically 101.5-142 cm (40-56 in) in length.
Masticophis schotti are found in Texas and through many of the northeastern states of Mexico.
Masticophis schotti is a non-venomous diurnal hunter, catching and eating its prey generally without killing it, as it does not constrict their prey. Prey includes mice, small birds, lizards and frogs, though young snakes are thought to consume insects. Active from March to late September, these snakes do not make good pets as their nervous habits are not well suited for captivity.
Female snakes lay 3-12 eggs during May and June, with the young emerging from their eggs in August.
Habitats frequented by Masticophis schotti include brushy thornscrub and mesquite lowlands to river valleys and the Gulf coastal plain.
Schott's whipsnake is not a protected species in Texas and can be legally collected with a hunting license.
In Texas, Masticophis schotti are found throughout south Texas, south of the Edwards Plateau.
