Conservation
IUCN Red List status is Least Concern, though localized populations face threats from habitat fragmentation, road mortality, and intentional killing.
Physical Description
Slender body with smooth scales and a pattern of dark blotches or rings bordered in black, overlying a gray, tan, or whitish background color. Head typically features a light-colored Y- or V-shaped mark on the rear.
Size & Dimensions
Specimen appears to be a juvenile, roughly 30 to 50 cm in length. Adults typically range from 60 to 130 cm.

Reproduction
Oviparous, laying clutches of 2 to 24 eggs in rotting logs, damp soil, or under rocks during early summer. Eggs typically hatch after about two months.
Look-alikes

Conservation Status
IUCN Red List status is Least Concern, though localized populations face threats from habitat fragmentation, road mortality, and intentional killing.
Cultural Significance
Historically associated with folklore claiming they milked cows in barns, which is false; however, they provide valuable ecosystem services by controlling rodent populations.
Notable Features
Exhibits Batesian mimicry, bearing a color pattern resembling that of more dangerous species, which helps deter potential predators.
