Habitat
Myotis evotis is found in a wide range of habitats, but is most commonly found in mixed coniferous forests, from humid coastal areas to montane forests. Elevation ranges from sea level on the Pacific Coast to 2,830 meters in the mountains of Wyoming. The habitat of M. evotis is largely dependent on what the bats use for their day roosts.

Food Habits
Myotis evotis is insectivorous. These bats emerge to feed approximately one hour after dark. They prey mainly on moths, but their diet also includes beetles, flies, and spiders. They can take prey from the air (hawk) as well as from surfaces (glean). The ability to incorporate both methods of foraging requires a pattern of flight that is slow and methodical, and which requires more energy compared to the flight patterns of faster-flying bats. Because the methodical flight requires more energy, these bats are forced to forage for prolonged periods.
