Until recent years, populations of the gray-banded kingsnake Lampropeltis mexicana alterna have confused systematists because of their extremely variable color morphology. The confusion was amplified by a lack of specimens in scientific collections. These snakes are secretive in behavior and their habitats are often inaccessible, making their collection most difficult. In addition, little has been published in the way of recent literature pertaining to the life history of this interesting reptile.
