Physical Description

Displays a distinct pattern of dark blotches (brown, grey, or reddish) bordered in black against a lighter grey, tan, or whitish background. The head often features a light Y-shaped or V-shaped marking on the back of the neck. Scales are smooth and glossy.

Diet & Feeding

Preys primarily on small mammals such as mice and voles, as well as lizards, birds, bird eggs, and occasionally other snakes. Hunts actively or waits in ambush, subduing prey through constriction.

Reproduction

Oviparous species. Females lay clutches of 2 to 24 eggs in rotting logs, loose soil, or under rocks during early summer, which hatch in late summer or early autumn.

Conservation Status

IUCN Red List status is Least Concern. Threats include habitat loss from urban development, road mortality, and intentional killing due to misidentification.
