Bats, familiar to speleologists, play an important part in animal ecology in caves. Indirectly by their guano, they provide a source of food for numerous cave-dwelling animals and directly, by their own more or less constant presence. 26 species of bats are known from Switzerland, 15 of which occur in caves. Miniopterus schreibersi is considered the only true cave-dweller. The exact distribution of the rare species, including those occurring outside caves, is found in the text and is also indicated on the accompanying maps.
