How to Identify the Common Wolf Snake (Identification Guide)

Key identifying features

The common wolf snake (Lycodon capucinus and related species) is identified by a series of narrow, pale crossbands or blotches on a brown to dark brown body, a slender build, and enlarged front teeth that give it its common name, though these are only visible on close inspection.

Coloration & pattern

The body is typically brown, dark brown, or blackish-brown, crossed by a series of narrow, irregular white, cream, or pale yellow bands or blotches, particularly prominent toward the front of the body and sometimes fading or breaking up toward the tail. The belly is generally pale, often white or cream, sometimes with dark speckling.

Head, eyes & scales

The head is only slightly distinct from the neck, moderately elongated, with large, dark eyes and round pupils typical of nocturnal snakes. There is often a pale band or collar-like marking near the neck. Scales are smooth and glossy, giving the body a sleek appearance.

Size & body shape

This is a small to moderate-sized snake, typically 40 to 75 cm (about 16 to 30 inches) long, with a slender, cylindrical body and a moderately long tail.

Range & habitat where you'll see it

The common wolf snake is widespread across South and Southeast Asia, often found in and around human habitation, gardens, agricultural areas, and forest edges, where it is frequently active at night.

How to tell it apart from look-alikes

Its banded brown-and-white pattern is often mistaken for that of venomous kraits, but the wolf snake's bands are typically narrower, more irregular, and less uniformly spaced, its head is more elongated and less rounded, and it lacks the smooth, glossy, strongly triangular cross-section and hexagonal scale row pattern of kraits. Careful comparison of band regularity and head shape helps separate the two.
