Western Fox Snake
Pantherophis ramspotti • Order: Squamata, Suborder: Serpentes, Family: Colubridae, Subfamily: Colubrinae, Genus: Pantherophis, Species: P. ramspotti
Venomous Status
Non-venomous (Aglyphous - lacks specialized venom-delivering fangs)
Danger Level
Harmless. They are not medically significant to humans and are generally beneficial for rodent control.
Geographic Range
Natural distribution includes the Upper Midwest region of the United States, specifically west of the Mississippi River in Iowa, South Dakota, Nebraska, Kansas, Minnesota, and Missouri.
Conservation Status
Least Concern (IUCN), though populations are threatened in some regions by habitat loss and fragmentation.
Physical Description
Yellowish to light brown ground color with large, dark brown or blackish dorsal blotches. The head is often a copper or reddish-orange color, which can lead to confusion with copperheads. Scales are weakly keeled and the pupils are round.
Size & Dimensions
Adults typically range from 36 to 60 inches (91-152 cm). This specimen appears to be a healthy adult of approximately 4 feet in length.
Habitat
Inhabits tallgrass prairies, agricultural fields, pastures, and woodland edges. They are often found near water sources or in proximity to farms and barns where rodents are plentiful.
Behavior & Temperament
Often docile but can be defensive if cornered. Known for vibrating their tail in leaf litter to create a rattling sound as a mimicry defense. Primarily diurnal or crepuscular depending on temperature.
Diet & Feeding
Active foragers that primarily consume small mammals (mice, voles, rats), bird eggs, and small birds. They are powerful constrictors.
Reproduction
Oviparous (egg-laying). Females lay clutches of 7 to 29 eggs in mid-summer, typically in rotting logs or subterranean burrows, which hatch in late summer or early fall.
Venom Profile
Venom Type
Non-venomous - no medically significant venom.

Look-alikes
Commonly confused with the Copperhead (Agkistrodon contortrix) due to head coloration, and the Timber Rattlesnake (Crotalus horridus) due to tail-vibrating behavior. Distinguished by round pupils and lack of facial pits.
Conservation Status
Least Concern (IUCN), though populations are threatened in some regions by habitat loss and fragmentation.
Cultural Significance
Highly valued by farmers for ecological services in controlling agricultural pests. Named 'Fox Snake' due to a pungent musk they can release that is said to smell like a fox.
Notable Features
Remarkable for their Batesian mimicry, where they imitate the sound of a rattlesnake by vibrating their tail against dry vegetation to ward off predators.
