Overview
The Variegated Wolf Snake is a moderately large, nocturnal colubrid distributed throughout Southeast Asia. It is notable for pronounced ontogenetic color change, with juveniles displaying bold banding that fades into a more variegated, blotched pattern in adulthood.
Despite its banded juvenile pattern closely resembling venomous kraits, this species is entirely non-venomous and does not pose a threat to humans.
How to identify it
- Juveniles strongly banded in black and white or cream; adults develop a more mottled, variegated pattern
- Smooth, glossy scales
- Flattened head with enlarged front teeth typical of Lycodon
- Round pupils
- Moderately robust body compared to smaller wolf snake species
The transition from bold juvenile banding to variegated adult pattern is a key identification feature; round pupils and lack of true krait dentition separate it from dangerously venomous banded kraits.
Habitat & range
Found in forests, plantations, and rural areas across Southeast Asia, including Thailand, Malaysia, Indonesia, and the Philippines. It shelters in leaf litter, tree hollows, and human structures.
Behavior, diet & reproduction
Strictly nocturnal, actively foraging at night. It can be defensive when cornered, biting readily, though this carries no significant medical risk.
Feeds on lizards, small mammals, and occasionally other snakes. Reproduction is oviparous, with clutches of several eggs laid in humid, sheltered sites.
