This snake spends most of its time underground and is rarely seen. It may be found under rocks or logs or in deserted termite mounds or may come to the surface after heavy rains. It is endemic to South Africa.

In winter large numbers of these snakes are known to congregate in suitable hiding places. The Black Thread Snake is small, averaging 12-16 cm in length. It feeds on invertebrates and is harmless to humans. Thread snakes are tricky to tell apart as most of them look alike. Distribution is one of the few ways to tell this species apart from other thread snake species.
