Lampropeltis calligaster calligaster
The Prairie Kingsnake is one of the seven constrictors that we have in the state of Missouri. They are from the family Colubridae, non-venomous snakes. They range through Illinois, Missouri, Louisiana, Nebraska, Kansas, Oklahoma, and Texas. Prairie Kingsnakes are found in prairies, open woods and rocky hillsides.
They have a coloration similar to a copperhead and are sometimes confused with this venomous snake. The Prairie Kingsnake's dark markings are circular along the back whereas the Copperhead's are hourglass.
The Prairie Kingsnake is immune to the venom of the Copperhead, Cottonmouth, and rattlesnake and so is able to eat these snakes along with lizards, small mammals and sometimes birds.
