Conservation
Evaluated as Least Concern by the IUCN Red List. Primary localized threats include habitat destruction, road mortality, and illegal collection for the pet trade.
Physical Description
Features a patterned back with dark blotches or saddle-like markings edged in black, overlaying a lighter grey or brownish-tan background. The head is relatively narrow with distinct dark patterning, and the body scales are smooth and glossy.
Size & Dimensions
This specimen appears to be a juvenile, approximately 30 to 45 cm in length. Typical adults reach lengths of 60 to 130 cm.
Habitat
Inhabits a diverse range of environments including deciduous forests, fields, pastures, rocky outcrops, and wetland edges. Often found sheltering under rocks, logs, boards, and other debris.
Diet & Feeding
Diet consists primarily of small rodents, lizards, amphibians, birds, and other snakes. It is a constrictor that actively hunts and overpowers prey by wrapping its body around it.
Reproduction
Oviparous species that mates in the spring. Females typically lay clutches of 2 to 24 eggs in rotting wood, leaf litter, or underground burrows during early summer, which hatch after approximately two months.
Look-alikes
Frequently confused with copperheads due to the dark blotched pattern, but can be distinguished by its round pupils, lack of facial heat-sensing pits, smoother head scales, and different head patterning.
Conservation Status
Evaluated as Least Concern by the IUCN Red List. Primary localized threats include habitat destruction, road mortality, and illegal collection for the pet trade.
Cultural Significance
Historically associated with folklore, including the old rural myth that they milk cows, though they are strictly carnivorous. They play an important ecological role in controlling rodent and pest populations.
Notable Features
Exhibits cryptic coloration that provides camouflage against leaf litter and rocky terrain. When threatened, it may vibrate its tail rapidly to mimic venomous snakes as a defense mechanism.
