Western Fox Snake
Pantherophis ramspotti • Order: Squamata, Suborder: Serpentes, Family: Colubridae, Subfamily: Colubrinae, Genus: Pantherophis, Species: P. ramspotti
Venomous Status
Non-venomous
Danger Level
Harmless; they are not dangerous to humans but may bite if handled aggressively.
Geographic Range
Upper Midwest of the United States, specifically west of the Mississippi River in states including Iowa, Minnesota, Nebraska, South Dakota, and northern Missouri.
Conservation Status
IUCN Least Concern; however, they face threats from habitat loss and are frequently killed by humans who mistake them for rattlesnakes.
Physical Description
Yellow to tan base color with large, dark brown or black dorsal blotches. The head often has a copper or reddish tint. Scales are weakly keeled. Pupils are round.
Size & Dimensions
The specimen appears to be an adult. Standard adult length ranges from 3 to 5 feet (91–152 cm), with a maximum recorded length of about 6 feet.
Habitat
Prairies, grasslands, pastures, and agricultural fields near water sources; often found in marshes and river valleys. Elevation is generally low to moderate plains.
Behavior & Temperament
Diurnal during spring and fall but becomes more nocturnal in summer heat. Defensive behaviors include tail vibrating (mimicking a rattlesnake) and releasing a musk that smells like a fox, hence the name.
Diet & Feeding
Primarily rodents (mice, voles, rats), but will also take birds and eggs. They are active hunters and powerful constrictors.
Reproduction
Oviparous (egg-laying). Females lay clutches of 7 to 29 eggs in mid-summer, which hatch in late summer or early autumn.
Venom Profile
Venom Type
Non-venomous - no medically significant venom.

Look-alikes
Commonly confused with the Bullsnake (Pituophis catenifer sayi) and the Timber Rattlesnake (Crotalus horridus). Distinguished from rattlesnakes by the lack of a rattle, round pupils, and lack of heat-sensing pits.
Conservation Status
IUCN Least Concern; however, they face threats from habitat loss and are frequently killed by humans who mistake them for rattlesnakes.
Cultural Significance
Highly beneficial to farmers due to their role in controlling rodent populations. They are often protected by local laws in certain states (e.g., Minnesota).
Notable Features
The species is famous for its mimicry of rattlesnakes through tail-shaking, which can be very convincing when performed against dry leaves or grass.
