Mexican milk snake (Lampropeltis triangulum annulata) - A "coral snake mimic," the milk snake has red and yellow bands separated by black. Non-venomous snakes with red, black, and yellow bands are often called "tricolors," or "candy-canes." It is not as common as the coral snake in our area and is seldom seen. It is quite harmless and usually good-tempered. This and its bright colors make it a popular snake in the pet trade.
