DeKay's Brownsnake
Storeria dekayi • Order: Squamata, Suborder: Serpentes, Family: Colubridae, Subfamily: Natricinae, Genus: Storeria, Species: Storeria dekayi
Venomous Status
Non-venomous; lacks fangs and venom glands.
Danger Level
Harmless; poses no threat to humans or pets. Generally docile and rarely bites, even when handled.
Geographic Range
Widely distributed throughout North America, including Southern Canada, the Eastern United States (east of the Rockies), Mexico, and Central America as far south as Honduras.
Conservation Status
Least Concern (IUCN). Highly successful and common throughout its range, though habitat fragmentation and pesticides affecting prey populations remain minor threats.
Physical Description
Small, slender brown to grayish-brown body with two rows of dark spots bordering a lighter vertebral stripe. The head is relatively small with a dark vertical mark below the eye and behind the jaw. Scales are keeled; pupils are round.
Size & Dimensions
The specimen appears to be an adult, approximately 9 to 13 inches (23-33 cm) in length. Species maximum is roughly 19 inches (49 cm).
Habitat
Generalist species found in forests, grasslands, and marshes, but highly adapted to anthropogenic environments such as gardens, vacant lots, and parks. Prefers moist soil and cover like rocks, logs, or leaf litter.
Behavior & Temperament
Primarily fossorial or secretive; often hides under debris. Mostly diurnal or crepuscular depending on temperature. When threatened, they may flatten their bodies to appear larger or release a foul-smelling musk.
Diet & Feeding
Specialized diet consisting mainly of soft-bodied invertebrates like earthworms, slugs, and snails. They use specialized teeth to extract snails from their shells; they are active foragers.
Reproduction
Viviparous (gives birth to live young). Typically produces a litter of 3 to 40 young (averaging 12-15) during late summer. Young are independent immediately after birth.
Venom Profile
Venom Type
Non-venomous - no medically significant venom.

Look-alikes
Often confused with the Red-bellied Snake (Storeria occipitomaculata), which has a bright red underbelly, or the Garter Snake (Thamnophis ssp.), which is usually larger with more distinct longitudinal stripes.
Conservation Status
Least Concern (IUCN). Highly successful and common throughout its range, though habitat fragmentation and pesticides affecting prey populations remain minor threats.
Cultural Significance
Economically and ecologically beneficial to gardeners as they act as a natural pest control by consuming slugs and snails that damage ornamental plants and crops.
Notable Features
Distinguished by its ability to thrive in densely populated urban environments where most other snake species have been extirpated. Its teeth are uniquely adapted for gripping and extracting snails from their shells.
