Conservation Status: Least Concern.

Southwestern myotis live in a variety of southwestern mountain habitats, from desert grasslands up into pine and mixed coniferous forest in the United States, and in desert and grassland in Mexico. These bats and two other myotis species, the long-eared myotis and the fringed myotis, are able to hover and pluck insects from surfaces; most myotis bats catch their prey on the wing. The three species are known as hovering-gleaning bats. The southwestern myotis probably hibernates in caves, but has not yet been found in hibernation.

Range: 85-101 mm

Range: 6-10 g
