Family

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

Conservation

IUCN Red List status is Least Concern, due to its wide distribution, high adaptability to human-altered environments, and stable populations.

Physical Description

Slender body with light brown or grayish-brown coloration, featuring a distinct pattern of dark spots along the back and sides, sometimes forming a vertebral stripe. A dark vertical bar is often present on the side of the head near the jaw. Scales are keeled.

Size & Dimensions

The specimen shown is likely a juvenile or small adult, approximately 20 to 30 cm in length. Typical adult size ranges from 23 to 38 cm, with a maximum recorded length around 52 cm.

Habitat

Found in a wide variety of habitats including deciduous forests, wetlands, fields, and heavily urbanized areas such as suburban gardens and parks. Often hides under rocks, logs, leaf litter, and debris.

Diet & Feeding

Primarily feeds on soft-bodied invertebrates, with a strong preference for slugs, earthworms, and snails, using active foraging techniques in moist microhabitats.

Reproduction

Ovoviviparous (gives birth to live young). Mating typically occurs in the spring, and females give birth to litters averaging 10 to 20 live young in late summer.

Conservation Status

IUCN Red List status is Least Concern, due to its wide distribution, high adaptability to human-altered environments, and stable populations.

Cultural Significance

Acts as an important natural pest controller in gardens and suburban yards by managing populations of slugs and snails that damage plants.

Notable Features

Highly urban-tolerant species frequently encountered in human-dominated landscapes, specializing in a diet of terrestrial mollusks which few other snakes exploit to the same degree.
