狐蛇（学名：Pantherophis vulpinus）主要分布在美国西部。

摄食

狐蛇主要以鼠类、鸟类或鸟卵为食，也有人称豹斑蛇具有食蛇性。狐蛇摄食时，对小的猎物直接咬住后吞咽，对较大的活体猎物则会绞杀后吞咽。

防御

狐蛇在遇到威胁时会用尾部拍打地面，模仿响尾蛇，并散发恶臭驱退进犯者。

繁育

狐蛇两岁性成熟，夏末秋初产卵，每胎约15至20枚，孵化期约为70天。

Fox snake or Foxsnake is the common name given to two species of North American rat snakes. Neither poses a threat to humans, but is killed by many people who mistake it for the venomous massasauga rattlesnake (Sistrurus catenatus), which shares parts of its geographic range with both species of fox snakes.
