The
Sri Lanka Wolf Snake is a nocturnal, terrestrial species endemic to
Sri Lanka. It is primarily found in the wet lowland and submontane forests, as well as in nearby well-wooded anthropogenic habitats. During the day, it shelters beneath fallen leaves, logs, and rubble on the forest floor, where the presence of moisture in its microhabitat is essential for its survival. It feeds mainly on frogs, geckos, skinks, and other small non-venomous snakes. The
Sri Lanka Wolf Snake closely resembles the venomous
Sri Lanka Krait (
Bungarus ceylonicus), a form of mimicry that often leads to it being mistakenly killed when encountered in houses, cultivations and home gardens. When threatened, it coils itself into a tight ball and conceals its head beneath the coils as a defensive behavior. This species is oviparous, with females laying between four and seven eggs.
