Non-venomous (Aglyphous)
Danger Level
Harmless - They are non-venomous and generally docile, though they may bite if handled aggressively.
Family
Order: Squamata, Suborder: Serpentes, Family: Colubridae, Subfamily: Colubrinae, Genus: Pantherophis, Species: P. vulpinus
Conservation
IUCN Least Concern, though regional populations are threatened by habitat loss, road mortality, and persecution due to confusion with venomous snakes.
Physical Description
Ground color is yellowish to light brown with prominent large, chocolate-brown to black dorsal blotches. In many individuals, the head can take on a copper or reddish-orange hue. Scales are weakly keeled.
Size & Dimensions
The specimen in the image appears to be a sub-adult or small adult, approximately 24-36 inches. Adults typically range from 3 to 5 feet (91-152 cm).
Habitat
Primarily found in wet prairies, marshes, and shorelines along the Great Lakes. They are semi-aquatic but often found in open fields or near farmland.
Behavior & Temperament
Generally calm but will perform a defensive display when threatened, which includes vibrating the tail (simulating a rattlesnake) and releasing a musky odor. Diurnal and active foragers.
Diet & Feeding
Active foragers that feed on small mammals (especially voles and mice), frogs, and ground-nesting birds or eggs. They kill via constriction.
Reproduction
Oviparous (egg-laying). Females lay clutches of 7-29 eggs in early summer, which hatch in late summer or early fall.
Venom Profile
Non-venomous - no medically significant venom.
Look-alikes
Often confused with the Copperhead due to its reddish head, or the Massasauga Rattlesnake due to its blotched pattern and tail-vibrating behavior. Can be distinguished by lacking heat pits and having round pupils.
Conservation Status
IUCN Least Concern, though regional populations are threatened by habitat loss, road mortality, and persecution due to confusion with venomous snakes.
Cultural Significance
Named 'foxsnake' because the musk they release when threatened smells similar to the scent glands of a red fox. They are highly beneficial to farmers for rodent control.
Notable Features
Remarkable for their ability to mimic rattlesnakes through tail vibration against dry leaves and for their distinctive copper-colored heads which frequently lead to misidentification as venomous species.
