Physical Description

Characterized by pale tan to pinkish-brown body coloration overlaid with distinctive darker, hourglass-shaped crossbands that are narrow at the top and wide at the sides. The head is noticeably wider than the neck, copper-red in color, and features vertical elliptical pupils and facial heat-sensing pits.

Size & Dimensions

Specimen is approximately 60-75 cm; typical adult length ranges from 60 to 90 cm, with maximum lengths exceeding 100 cm.

Habitat

Deciduous forests, mixed woodlands, rocky hillsides, wetland edges, and suburban areas near wooded patches, typically at elevations from sea level to 1,500 meters.

Diet & Feeding

Predominantly carnivorous, feeding on small mammals, birds, frogs, lizards, and large insects. Utilizes an ambush hunting strategy, often remaining motionless in leaf litter to strike passing prey.

Reproduction

Viviparous (gives live birth), producing litters typically ranging from 3 to 10 young born in late summer or early autumn.

Conservation Status

IUCN Red List status is Least Concern. Threats include habitat destruction, intentional killing by humans, and road mortality.

Cultural Significance

Plays an important role in local ecosystems by controlling rodent and small mammal populations. Frequently encountered near human habitations due to suburban encroachment.

Notable Features

Features specialized heat-sensing pits located between the eye and the nostril, which allow the snake to detect thermal radiation from warm-blooded prey in complete darkness.
