Some snakes of the genus might be found hiding under logs and rocks as long as there’s sufficient humidity.
Otherwise, these small snakes move around looking for food. They prefer to eat ants or termites.
There’s growing evidence to show these snakes can even live in ant nests for up to a few days to eat more ants.
