One of the smallest bats. It has tufts of hair on both sides of its mouth, thus the name of the species. It is found in open landscapes with isolated trees. In summer, it sleeps in the holes and crevasses of trees, or occasionally in nesting boxes or behind window shutters. In winter, it hibernates in mining galleries or caves. It takes to the air at the first signs of dusks, and can in fact sometimes even be spotted hunting during the day. Whiskered Bats are generally solitary animals. They can be found all across Europe, with the exception of areas in the Mediterranean, Scandinavia, and Britain.
