Habitat and Ecology [top]

Habitat and Ecology:This species can be found in arid tropical and lower Sonoran life zones. It has been reported in desert matorral, tropical deciduous forest, oak forest, and pine-oak forest. It roosts in caves and empty houses; an estimated 5,000 females and young were found in a large cave; also, a maternity colony of 100 females and young were found in the crevices of an abandoned house. This species can be found roosting with other bats species. It mates at the end of summer and during autumn, sometimes into the following spring. Pregnant females were found in May and June, with parturition occurring in late June and early July (Alvarez-Catañeda and Bogan 1998).
Continuing decline in area, extent and/or quality of habitat:Yes

Threats [top]

Major Threat(s): This species should be considered threatened because of its restricted distribution, but also by habitat loss associated to touristic development. However, the species can persist at some disturbed areas, and even survive at periurban zones (Ceballos 2014).

Conservation Actions [top]

Conservation Actions: It is included in one protected area, the Reserve of the Biosfere "La Laguna". Its preference for caves might put it under some risks.
