Conservation
IUCN Red List status is Least Concern, though local populations can be affected by habitat fragmentation, illegal collection for the pet trade, and road mortality.
Physical Description
Slender body with smooth scales, featuring a distinct patterned coloration consisting of alternating bands or blotches of dark brown or black, reddish-orange or red, and white or yellowish cream. The head often features a light-colored V- or Y-shaped mark on the nape, and pupils are round.
Size & Dimensions
Estimated specimen length is approximately 40 to 60 cm (juvenile or subadult). Typical adult size ranges from 50 to 130 cm.
Habitat
Found in a wide variety of habitats including fields, forests, agricultural land, rocky hillsides, and prairies, typically from sea level up to around 2,000 meters elevation. They are secretive and spend much of their time under logs, rocks, bark, and debris.
Diet & Feeding
Diet consists primarily of rodents, lizards, amphibians, birds, and occasionally other snakes. They are active hunters and constrictors, subduing prey by wrapping coils around it.
Reproduction
Oviparous species, laying clutches typically ranging from 2 to 17 eggs in early summer under logs, rocks, or loose soil, with incubation lasting about two months.
Conservation Status
IUCN Red List status is Least Concern, though local populations can be affected by habitat fragmentation, illegal collection for the pet trade, and road mortality.
Cultural Significance
Historically associated with folklore (such as the myth that they milk cows), but ecologically valuable as natural pest control by helping regulate rodent populations.
Notable Features
Exhibits Batesian mimicry in certain subspecies, mimicking the warning coloration of coral snakes to deter potential predators.
