The small-footed myotis is a common bat of arid uplands in California. In coastal California it occurs from Contra Costa Co. south to the Mexican border. It occurs in a wide variety of habitats, primarily in relatively arid wooded and brushy uplands near water. The summer and winter ranges appear to coincide, but there are few records from winter.
Prey includes moths, flies, beetles, and bugs.
Foraging flight is slow and maneuverable. The small-footed myotis often is seen foraging among trees and over water. Separate night roosts may be used, and have been found in buildings and caves. Groups of 50, or more, may inhabit a hibernation site. Maternity colonies of females and young are found in buildings, caves, and mines.
