This bat is commonly found in attics and buildings during summer months in maternity colonies. It weighs about half an ounce and has a wingspan of nine to 11 inches. It prefers to live in forests near water.

One baby is born in spring or summer. In winter, this bat hibernates in caves.

The little brown myotis occurs throughout Oregon in a wide variety of habitats, but seems especially prone to establish residence near a lake, pond, or stream.
