Conservation

Listed as Least Concern on the IUCN Red List, though local populations face pressures from habitat fragmentation, road mortality, and illegal collection for the pet trade.

Physical Description

Displays a contrasting pattern of dark grey or black blotches edged with lighter grey or whitish margins along the back and sides, set against a pale background. The head features distinct dark markings including a pale Y- or V-shaped patch on the rear of the crown, and the body scales are smooth and glossy.

Size & Dimensions

The pictured specimen appears to be a juvenile or subadult measuring roughly 40 to 60 cm. Adults typically range from 60 to 130 cm in total length.

Habitat

Occupies a diverse array of terrestrial habitats including mixed forests, fields, agricultural lands, rocky outcrops, and wetland edges, typically from sea level up to moderate elevations where suitable cover like logs and rocks is abundant.

Diet & Feeding

Predominantly carnivorous, feeding on a wide variety of prey including small rodents, lizards, birds, bird eggs, and other snakes. It is an active forager that often uses constriction to subdue its prey.

Reproduction

Oviparous species that mates in the spring (May to June) and deposits clutches typically ranging from 2 to 24 eggs beneath rotting logs, rocks, or loose soil during mid-summer, with incubation lasting around two months.

Conservation Status

Listed as Least Concern on the IUCN Red List, though local populations face pressures from habitat fragmentation, road mortality, and illegal collection for the pet trade.

Cultural Significance

Often beneficial in agricultural ecosystems due to rodent control, though historically subjected to unwarranted persecution due to mistaken identity with pit vipers.

Notable Features

Noted for its glossy scales, secretive habits, and the ability to vibrate its tail rapidly in dry leaves when threatened to mimic the sound of a rattlesnake.
