Natural History

The Western Threadsnake is a very secretive snake that can be found under rocks, wood, debris, among plant roots, or in crevices. This species eats small insects and their larvae and eggs, spiders, centipedes, and millipedes, but their favorites are ants and termites. When searching for food, a Western Threadsnake will hunt until it finds an ant pheromone trail and will follow it back to the nest to eat the ants. This snake appears on the surface at night but may be active underground at other times.

Fun Facts

Western Threadsnake spends its entire life underground in burrows, and since it has no use for vision, its eyes are non-functional. These snakes are sometimes called blind snakes. It has been found over 60 feet underground.
