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; posing no threat to humans or pets. Defensive behavior is limited to musk secretion or rarely a bluff strike with a closed mouth.
Geographic Range
Extensive range across North America, from southern Canada (Ontario, Quebec) through the eastern and central United States, and south into Mexico and Central America (Guatemala, Honduras).
Conservation Status
Least Concern (IUCN). Population is stable and they are remarkably resilient to habitat fragmentation and urbanization.
Physical Description
Small, slender snake with keeled scales. Coloration is typically light brown to grayish with a distinct lighter mid-dorsal stripe bordered by two rows of dark spots or 'checkerboard' crossbars. The head is relatively small with large eyes and round pupils. Dark markings are usually present behind the eyes and on the neck.
Size & Dimensions
Typical adult size ranges from 23 to 33 cm (9 to 13 inches). The specimen in the image appears to be an adult or sub-adult based on proportions relative to the substrate.
Habitat
Highly adaptable, found in forests, grasslands, and marshes, but particularly well-known for thriving in suburban and urban environments. Often found under debris, rocks, or logs in moist soil areas.
Behavior & Temperament
Secretive and docile. Primary defense is crypsis (camouflage) or fleeing. If handled, they may release a foul-smelling musk from the cloaca. They are primarily diurnal or crepuscular depending on temperature.
Diet & Feeding
Specialized diet consisting primarily of soft-bodied invertebrates like earthworms, slugs, and snails. They possess specialized teeth and jaw mechanics to extract snails from their shells.
Reproduction
Viviparous (gives birth to live young). Litter sizes typically range from 3 to 15 neonates, born in late summer (July to September).
Venom & Safety
Venom Type
Non-venomous - no medically significant venom.
First Aid Advice
No medical treatment necessary for a bite other than standard wound cleaning. Simple soap and water wash is recommended to avoid secondary infection.
Look-alikes
Commonly confused with the Garter Snake (Thamnophis sirtalis), which usually has more prominent longitudinal stripes, or the Red-bellied Snake (Storeria occipitomaculata), which has a bright red venter and spot on the nape.
Conservation Status
Least Concern (IUCN). Population is stable and they are remarkably resilient to habitat fragmentation and urbanization.
Cultural Significance
Valued by gardeners as 'beneficial' wildlife due to their consumption of slugs and snails that damage ornamental plants. They are one of the most frequently encountered snakes in North American backyards.
Notable Features
Noted for its extreme 'urban tolerance.' It is one of the few snake species that maintains high population densities in city parks and vacant lots due to its ability to find food and cover in small patches of vegetation.
