DeKay's Brownsnake
Storeria dekayi • Order: Squamata, Suborder: Serpentes, Family: Colubridae, Subfamily: Natricinae, Genus: Storeria, Species: Storeria dekayi
Venomous Status
Non-venomous (aglyphous)
Danger Level
Harmless. These snakes are not a threat to humans or pets; they rarely bite even when handled, preferring to release musk or flatten their bodies.
Geographic Range
Extensive range across North America, from southern Canada (Ontario, Quebec) through the eastern half of the United States, and south into Mexico and Central America as far as Honduras.
Conservation Status
Least Concern (IUCN). Population is stable, though they face local threats from habitat destruction, pesticides (which kill their prey), and road mortality.
Physical Description
Small, slender snake typically brown to grayish-brown. It features two parallel rows of small dark spots bordering a lighter central dorsal stripe. The head is relatively small with large eyes and round pupils. Scales are keeled (ridged). There is usually a dark temporal blotch behind the eye.
Size & Dimensions
The specimen pictured appears to be a juvenile or small adult, likely around 6-10 inches. Adult range is typically 9 to 13 inches (23-33 cm), with a maximum recorded length of about 20 inches.
Habitat
Highly adaptable; found in wetlands, grasslands, and forests, but notoriously common in urban and suburban environments like gardens, parks, and vacant lots. They prefer moist soil and cover objects like logs, rocks, or debris.
Behavior & Temperament
Secretive and docile. Primary activity is diurnal or crepuscular, though they can be nocturnal in hot weather. Defensive behaviors include flattening the body to appear larger and excreting a foul-smelling musk from the cloaca.
Diet & Feeding
Specialized carnivore feeding primarily on soft-bodied invertebrates such as earthworms, slugs, and snails. They use their specialized teeth to pull snails from their shells. They are active foragers rather than constrictors.
Reproduction
Viviparous (gives birth to live young). Typical litters range from 5 to 25 neonates, born in late summer (July to September). No parental care is provided after birth.
Venom & Safety
Venom Type
Non-venomous - no medically significant venom.
First Aid Advice
If bitten (which is rare), wash the area with soap and water to prevent secondary infection. No medical intervention or antivenom is necessary. Identification confirmation is recommended to rule out similar-looking venomous juveniles (like Copperheads), though the markings are distinct.
Look-alikes
Often confused with the Garter Snake (Thamnophis sirtalis), but lacks the distinct clean yellow stripes. Also confused with the Red-bellied Snake (Storeria occipitomaculata), which has a bright red underside and three light spots behind the head.
Conservation Status
Least Concern (IUCN). Population is stable, though they face local threats from habitat destruction, pesticides (which kill their prey), and road mortality.
Cultural Significance
Ecologically vital for natural pest control in gardens, as they consume large quantities of slugs and snails that damage ornamental and food plants. Often one of the few snake species that thrives in human-altered landscapes.
Notable Features
One of the most 'urban-tolerant' snakes in North America. Their ability to survive in small patches of vegetation in major cities makes them a frequent encounter for suburban homeowners. They possess specialized jaw morphology to facilitate the consumption of terrestrial mollusks.
