The Indiana myotis is a medium sized bat with longer ears and a short face. Its fur ranges from grayish in color to chestnut, with more dull-lead colored fur at the base of the hairs and pinkish to cinnamon colored fur underneath the body. The Indiana myotis will forage for a variety of aerial insects as part of its diet. In the summer, the Indiana bat will roost underneath the exfoliating bark of trees, especially dead or dying trees known as snags. During the winter, hibernation sites occur within cold caves, often limestone caves, containing pools of water. Only a few of these caves are known to be used by this species, further compounding the species' susceptibility to disturbance during hibernation.
The Indiana myotis was one of the first species of bats in the United States to be listed as endangered by the U.S. Fish and Wildlife Service. Despite measures to protect the species' winter hibernacula, populations continue to decline, indicating that the species is threatened within their summer range as well. Threats include pesticide use and deforestation which limit suitable summer habitat.
The Indiana bat can be found throughout the eastern United States, within the central Midwest, upper New England states, and south into the northern Gulf States and far northern Florida
