Overview

The Rough Earth Snake is a diminutive, secretive colubrid widespread across the southeastern United States. It is frequently found by homeowners while gardening, as it lives just beneath the surface in loose soil and leaf litter.

Completely harmless to humans, it lacks venom and relies on its small size and burrowing habits to avoid detection.

How to identify it

  • Small, slender body rarely exceeding 25 cm (10 in)
  • Brown, gray, or reddish-brown dorsal coloration, usually unpatterned
  • Keeled (rough-textured) dorsal scales, giving the species its common name
  • Pointed snout adapted for burrowing
  • Pale, unmarked belly

It closely resembles the Smooth Earth Snake but is distinguished by its keeled scales, which feel rough to the touch, versus the smooth scales of that species.

Habitat & range

This species favors moist woodlands, forest edges, and suburban gardens with abundant leaf litter, loose soil, or decaying logs. It is widespread across the southeastern United States, from the Carolinas west to Texas and Oklahoma, typically remaining hidden underground or under surface cover.

Behavior, diet & reproduction

The Rough Earth Snake is fossorial and secretive, most active at dusk and after rain. It feeds primarily on earthworms and soft-bodied insect larvae, using its pointed snout to probe through soil. It is inoffensive when handled and gives live birth, with females bearing small litters of a few young in late summer.
