The ornate box turtle occurs in the United States and Mexico. T. o. ornata occurs in western Indiana and eastern Wyoming, south to south-western Louisiana and eastern New Mexico. T. o. luteola ranges from Texas and south-eastern Arizona south into north-eastern Sonora and northern Chihuahua, Mexico (4).
T. o. ornata inhabits plains and gently rolling grasslands, with scattered low brush but no trees. T. o. luteola occurs in more arid habitats, in semi-desert to desert, where it favours areas with low soil temperatures, high air temperatures, and low humidity levels (4).
