Family

Order: Squamata, Suborder: Serpentes, Family: Colubridae, Subfamily: Natricinae, Genus: Storeria, Species: Storeria dekayi

Conservation

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.

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.

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.
