    Agkistrodon contortrix

    Sit and Wait Predator

    The copperhead is also called the death adder, chunk head, and dry-land moccasin. Its scientific name is Agkistrodon contortrix. It is a pit viper, and like all pit vipers, it is an ambush predator. The copperhead will sit and wait in dry leaf matter waiting for an animal to come into its path.

    Behavior

    Unlike many of the viperids in North America, the copperhead will not flee the area if confronted by a human. Instead it will coil up and freeze. (The attached species photo was taken in a patch of dry leaves in North Texas. We were able to get many photos of the copperhead because it did not slither away from the area.)

    What do Copperheads eat?

    About 90 percent of the diet of a copperhead consists of mice, voles, and other small rodents. They will also eat frogs and large insects (such as cicadas).
