This nonvenomous snake is small and slender; it prefers staying hidden under the leaf litter, rocks, and compost piles, where it will live most of its life. Rough earth snakes are so small they are sometimes mistaken for the worms they love to eat.

Incredible Rough Earth Snake Facts

  • Juvenile rough earth snakes are often confused for ring-necked snakes because they have a light band behind their head.
  • They don’t constrict their prey and swallow it still alive.
  • Rough earth snakes have keeled scales and are often confused for De Kay’s brown snake.

Rough Earth Snake Scientific Name and Classification

The rough earth snake’s current scientific name is Haldea striatula. Like many organisms, this species has changed names several times over the years. Since its first description in 1766 by Carl Linnaeus with the name Coluber striatulus, these snakes have been classified into several genera, including Natrix, Conocephalus, Falconeria, and Virginia. In the early 2000s, genetic research results showed that many reptiles had been classified into genera that didn’t fit precisely, so scientists moved them. The most recent change was in 2013, when scientists changed the generic name back from Virginia to Haldea.

They have several common names, including brown snake, ground snake, brown ground snake, little striped snake, small brown viper, small-eyed brown snake, southern ground snake, striated viper, and worm snake.

Rough Earth Snake Appearance

The rough earth snake measures 7-10 inches as an adult. The females are usually longer and heavier than the males, but otherwise, there’s little visible difference. This snake doesn’t typically have a pattern but is a solid brown, reddish, or gray color with slightly keeled scales, and a tan to whiteish-colored belly. Its snout is pointed, which helps it root around and burrow into moist soil.

Juveniles have light-colored collars and look somewhat like ring-necked snakes. However, unlike ring-necked snakes, rough earthsnakes have drab belly colors, and their neck collars don’t fade as they grow.

In general, rough earth snakes are most likely to be mistaken for De Kay’s brown snake, which is generally a little bigger, with a more rounded snout and light brown and dark markings on its back and neck.

Rough Earth Snake Behavior

This species is very shy and reclusive; it’s not at all aggressive, has no venom, and is completely harmless when encountered. It has teeth, however, doesn’t bite anything except its prey. The rough earth snake’s typical response to a threat is first to sit still, then attempt escape. Finally, it musks the individual threatening it. When a snake musks you, it’s defecating on you. It smells awful and is an effective defense against would-be predators.

Depending on the region, rough earth snakes are generally active beginning in early spring and brumate through the colder months beginning in fall. The further north the snakes live, the shorter their active cycle.

Although they’re typically most active during the day, warm wet weather conditions will also bring them out at night. To avoid the heat of the summer, they switch to more nocturnal habits.

Rough Earth Snake Habitat

Rough earth snakes inhabit a wide area of the southeastern United States. They’re found in fourteen states from North Carolina, south to Florida, and west to Texas. These secretive snakes are most often seen in the spring and fall when they’re most likely to be moving to or from brumation sites and breeding.

A fossorial species, the rough earth snake hides under rocks, logs, ornamental stones, in compost piles, and leaf litter. It rarely ventures out in the open and prefers to stay hidden. They’re also found in trash piles, garden beds and in various forested habitats with plenty of ground cover. These snakes use their pointed snouts to help dig through loose soil and debris as they search for prey.

Rough Earth Snake Diet

The rough earth snake is one of many snakes that help control the insect population. They help prevent snails and slugs from overtaking your garden, as their diet is completely made up of invertebrates. Its favorite food is earthworms, but it also eats snails, slugs, insect eggs, sow bugs, and larvae. This tiny predator doesn’t bother to subdue its prey and simply swallows it.

Rough Earth Snake Predators, Threats, Conservation, and Population

While they are predators, earthsnakes are not apex predators. Their small size means they become food for many larger animals. Other snakes, predatory birds, and mammals will eat them, given the chance.

According to the IUCN Redlist of Threatened Species, rough earth snakes aren’t in any danger of becoming extinct. The 2007 assessment determined that they have a stable population that thrives, even in urban gardens and parks.

These snakes are pretty flexible in where they live, and whether it’s an urban area or a forest doesn’t seem to make a difference to rough earth snakes. They enjoy a wide distribution across the southeastern United States and are fairly tolerant of habitat changes. All one of these really needs to thrive is a dark, moist location with lots of invertebrates to eat and places to hide.

Rough Earth Snake Reproduction, Babies, and Lifespan

Rough earth snakes mate in the spring, between March and May or June, the more northern populations tend to breed later in spring than their southern cousins. Between June and September, the females give birth to between three and eight four-inch-long babies. Not much is known about their lifespan, but if it’s like similar snakes, they may live up to about seven years.

  • De Kay’s brown snake may look like a rough earth snake, but it’s a little bigger.
  • Rim rock crowned snakes are also sometimes mistaken for rough earth snakes, and vice versa.
  • Another look-alike, smooth earth snakes live in similar habitats.
