A Mexican species that enters the United States in extreme southern Texas, New Mexico, and Arizona. The single Texas record is from Santa Ana National Wildlife Refuge in Hidalgo County. These bats inhabit deep canyons where they use caves and mine tunnels as day roosts. C. mexicana feeds on fruit, pollen, nectar, and probably insects.
