All of the native bat species in Greater Yellowstone are insectivores. A single little brown bat (Myotis lucifugus, the most common species) can consume 1,200 mosquito-sized insects in an hour. The distribution of bats is usually concentrated near sources of food, water, and roosting structures. They roost in natural habitats, including thermally heated caves, as well as in bridges, buildings, abandoned mines, and other man-made structures, which can lead to conflicts with human use and preservation of historical sites.
