Family
Order: Squamata, Suborder: Serpentes, Family: Colubridae, Subfamily: Natricinae, Genus: Storeria, Species: Storeria dekayi
Conservation
IUCN Red List: Least Concern. They are stable and abundant, though they face threats from habitat loss and high mortality on roads/residential areas.
Physical Description
Small, slender snake with a base color of light brown to grayish-brown. It features two parallel rows of dark spots bordering a light dorsal stripe. The head is small with dark patches on the temples, and the scales are keeled (rough). The eyes are relatively large with round pupils.
Size & Dimensions
The specimen in the image appears to be an adult, approximately 9 to 12 inches (23-30 cm) long. Typical adult size for the species is 9 to 13 inches, with a maximum record of about 19 inches.
Habitat
Highly adaptable; found in moist woodlands, meadows, marshes, and frequently in residential areas such as gardens, parks, and under urban debris. They prefer microhabitats with damp soil and cover like logs or stones.
Behavior & Temperament
Secretive and docile. These snakes are primarily diurnal or crepuscular but may become nocturnal in hot weather. They are slow-moving and rely on camouflage and hiding under cover (fossorial tendencies).
Diet & Feeding
Specialist feeders that eat primarily soft-bodied invertebrates such as earthworms, slugs, and snails. They use their specialized teeth to pull snails out of their shells.
Reproduction
Viviparous (gives birth to live young). Mating occurs in spring or fall, and females give birth to 3 to 40 young in late summer, usually between July and September.
Venom Profile
Non-venomous - no medically significant venom.
Look-alikes
Often confused with the Garter Snake (Thamnophis sirtalis) which is larger and has distinct longitudinal stripes, or the Red-bellied Snake (Storeria occipitomaculata) which has a bright red underside and small spots on the neck.
Conservation Status
IUCN Red List: Least Concern. They are stable and abundant, though they face threats from habitat loss and high mortality on roads/residential areas.
Cultural Significance
Ecologically beneficial in residential gardens as they act as natural pest control for slugs and snails that damage plants. They are one of the most common snakes found in urban North American environments.
Notable Features
Features specialized teeth and jaw morphology that allows them to extract snails from shells efficiently. They are often mistaken for 'baby' snakes of larger species due to their small adult size.
