Order: Squamata, Suborder: Serpentes, Family: Colubridae, Subfamily: Natricinae, Genus: Haldea, Species: Haldea striatula
Conservation
IUCN Red List: Least Concern. Generally common throughout its range, though habitat loss and pesticide use (affecting prey) can impact local populations.
Physical Description
A small, slender snake with a pointed snout and small eyes. Dorsal scales are heavily keeled (ridged). Coloration is typically uniform gray, brown, or reddish-brown. The belly is plain cream or light tan. Unlike similar species, they lack distinct patterns or neck rings.
Size & Dimensions
The specimen in the image appears to be an adult, approximately 7 to 9 inches (18–23 cm) long. Typical adult range is 7 to 10 inches; maximum recorded length is around 12.7 inches.
Habitat
Primarily fossorial (burrowing). Prefers moist soils, deciduous woodlands, pine forests, and suburban gardens. Commonly found under leaf litter, logs, rocks, or garden debris.
Behavior & Temperament
Highly secretive and docile. Primarily nocturnal or crepuscular, spending most of the day underground. When threatened, they may release a foul-smelling musk but rarely attempt to strike.
Diet & Feeding
Specialized feeder primarily consuming earthworms. They also occasionally eat slugs, snails, and soft-bodied insect larvae. They use active foraging to find prey in loose soil.
Reproduction
Viviparous (gives birth to live young). Breeding occurs in spring, and females give birth to 3–8 young in late summer or early fall. Newborns are about 3–4 inches long.
Venom Profile
Non-venomous - no medically significant venom.
Look-alikes
Commonly confused with the Smooth Earth Snake (Virginia valeriae), which has smooth scales and a more rounded snout, and the DeKay's Brownsnake (Storeria dekayi), which has two rows of dark spots along the back.
Conservation Status
IUCN Red List: Least Concern. Generally common throughout its range, though habitat loss and pesticide use (affecting prey) can impact local populations.
Cultural Significance
Ecologically beneficial in residential areas as they manage worm and slug populations. They are often one of the most common snakes found in backyard gardening due to their preference for mulch and flowerbeds.
Notable Features
Features a single internasal scale and a loreal scale that touches the eye, which helps herpetologists distinguish it from similar small brown snakes. It is one of the smallest snake species in its range.
