Conservation
IUCN Red List status is Least Concern, as the species is widespread, highly adaptable, and populations remain stable despite habitat alteration.
Physical Description
Brown to grayish-brown coloration with a lighter vertebral stripe bordered by small, dark spots or dashes running down the back. The scales are keeled, and the head is relatively small and distinct from the neck. Eyes are moderately sized with round pupils.
Size & Dimensions
Specimens typically range from 20 to 33 cm (8 to 13 inches) in total length, with a maximum recorded length around 52 cm (20 inches).
Habitat
Highly adaptable, found in deciduous forests, fields, marshes, and heavily urbanized areas such as suburban gardens, parks, and vacant lots. Often shelters beneath logs, rocks, bark, and man-made debris.
Diet & Feeding
Specialized diet consisting primarily of slugs, snails, earthworms, and soft-bodied insects. Forages actively in microhabitats where damp conditions support invertebrate prey.
Reproduction
Viviparous (gives birth to live young), producing litters ranging from 3 to over 20 young in the late summer, typically between August and September.
Look-alikes
Frequently confused with the Red-bellied Snake (Storeria occipitomaculata) and juvenile garter snakes (Thamnophis spp.). Distinguished by the lack of bright red/orange belly coloration and the specific pattern of dark spots along the dorsal stripe.
Conservation Status
IUCN Red List status is Least Concern, as the species is widespread, highly adaptable, and populations remain stable despite habitat alteration.
Cultural Significance
Acts as an effective natural controller of garden pests such as slugs and snails, contributing significantly to urban and suburban ecosystem pest regulation.
Notable Features
Exhibits specialized tooth morphology and jaw adaptations tailored for extracting snails and slugs from their shells.
