It lives in caves at altitudes of 1200-2000 m and lives in groups, hunting insects for food.

Often with hoofed bats, mouse-ejected bats, broken wing bats, etc., there is also a single population of hibernating in water caves, resting often in sheets or rows hanging upside down on the rock wall, and with a wing film wrapped around the body, the height of the habitat is generally 2-4 meters. In the evening, they go out to forage for food and catch insects, especially mosquitoes. The intestinal length is about 2.6 times of the body length (2.4-3.1), and the stomach contents are mosquitoes, lepidoptera insects and a few undigested elytrons.
