DeKay's Brownsnake
Storeria dekayi • Order: Squamata, Suborder: Serpentes, Family: Colubridae, Subfamily: Natricinae, Genus: Storeria, Species: Storeria dekayi
Venomous Status
Non-venomous
Danger Level
Harmless; they pose no threat to humans or pets. Their primary defense is musk secretion or flattening the body to look larger.
Geographic Range
Widely distributed across North America, from southern Canada (Ontario, Quebec) through the eastern half of the United States, and south into Mexico and Central America (Guatemala, Honduras).
Conservation Status
IUCN Red List: Least Concern. The species is abundant and stable, though local populations can be affected by heavy pesticide use which reduces their prey base.
Physical Description
Small, slender snake with keeled scales. Typically grayish-brown to tan with a lighter dorsal stripe bordered by two rows of dark spots (sometimes resembling a ladder). The head is small with dark markings below the eyes and on the temples. Pupils are round.
Size & Dimensions
The specimen in the image appears to be a small adult or sub-adult, roughly 6-10 inches in length. Standard adult size ranges from 9 to 13 inches (23-33 cm), with a maximum record of about 20 inches.
Habitat
Generalist species found in various habitats including wetlands, forests, and grasslands. They are highly adaptable to human environments, frequently inhabiting residential gardens, parks, and vacant city lots. Often found under debris or rocks.
Behavior & Temperament
Very docile and rarely attempts to bite. Primarily fossorial or secretive, hiding under cover. Most active during the day (diurnal) in spring and fall, but may become crepuscular or nocturnal during hot summer months.
Diet & Feeding
Specialized diet consisting mainly of soft-bodied invertebrates such as earthworms, slugs, and snails. They have specialized teeth and jaw structures to help extract snails from their shells.
Reproduction
Viviparous (gives birth to live young). Typically produces 12 to 20 young in late summer (July–September). Breeding usually occurs shortly after emerging from hibernation in the spring.
Venom & Safety
Venom Type
Non-venomous - no medically significant venom.
First Aid Advice
No medical intervention is necessary for a bite. Wash the area with soap and water to prevent secondary infection. They are completely harmless to humans.
Look-alikes
Often confused with the Garter Snake (Thamnophis sirtalis) or Red-bellied Snake (Storeria occipitomaculata). Garter snakes are usually larger with more distinct striped patterns; Red-bellied snakes have a bright red or orange underside and three pale spots behind the head.
Conservation Status
IUCN Red List: Least Concern. The species is abundant and stable, though local populations can be affected by heavy pesticide use which reduces their prey base.
Cultural Significance
Highly beneficial to gardeners and farmers as they provide natural pest control by consuming slugs and snails that damage host plants. They are one of the few snake species that thrive in urban environments.
Notable Features
Known for its 'slug-hunting' lifestyle; it possesses unique dental adaptations to grip slippery prey. It is frequently the first snake species encountered by urban dwellers due to its tolerance for fragmented habitats.
