That’s not an earthworm, it’s a snake!
Meet the Texas Blind Snake, Leptotyphlops dulcis. Also known as the Plains Thread Snake. These tiny critters only grow to be 5-8″ in length, and with their pinkish brown coloration they are easy to mistake for earthworms.
Texas Blind Snakes are great friends to humans, in that their diets consist of mainly termite and ant larvae. Yet another snake that is great to have around the yard!
Despite the misleading name, Texas Blind Snakes are not actually blind. Their eyesight is minimal, but they can perceive changes in light with their small eyes. They communicate with other snakes of their species through the use of pheromones.
These snakes are nocturnal, and are burrowers. Because of these factors, they are not easy to see, despite their wide geographic range in Texas. Not to mention their incredibly small size! If you happen to see one, be sure to thank it for controlling ant and termite populations.
