Habitat: Gypsum caves and, less commonly, in buildings.

Habits: The subspecies found in most of Oklahoma is migratory and does not hibernate. Beginning in August bats migrate to southern Texas and Mexico. Breeding occurs on the winter range from February until early April. After breeding, the females migrate northward to form large nursery colonies. Young (one per female) are born in June and July. Males also migrate northward in spring, but use smaller, non-nursery caves and occasionally buildings; some males do not migrate, but remain on the winter range. The diet consists of moths, and other flying insects. They may travel up to 50 miles each night to feed.
