Coluber constrictor etheridgei, commonly known as the tan racer, is a subspecies of nonvenomous snake in the family Colubridae, a subspecies of the eastern racer (Coluber constrictor). The subspecies is native to the southern United States.
C. c. etheridgei is found in west-central Louisiana and adjacent eastern Texas.
The subspecific name or epithet, etheridgei, is in honor of the American herpetologist .
The tan racer, as its name implies, is typically a solid tan in color. Juveniles have a pattern of dark brown dorsal blotches, which fade to solid tan at about a year of age. The underside is typically gray or white, sometimes with yellow spotting. It typically grows from .75 â 1.5 m (30 to 60 inches) in total length (including tail). It has large eyes, with round pupils, and excellent vision.
Like all racers, the tan racer is diurnal and highly active. Its diet consists of a wide variety of prey, but primarily includes rodents, and lizards. It is fast moving, and generally seeks to use its speed to escape if approached.
The tan racer prefers habitats of pine flatwoods.
C. c. etheridgei is oviparous. Mating occurs in the spring, and a clutch of approximately 30 eggs is laid typically in the month of May, to hatch mid summer.
