In buildings these bats were found throughout the year with the exception of June and July, and they do not reproduce there. One winter colony was found in a crack in a rock. According to the authors' material and according to data in literature the relation of different components of populations to different types of shelters is evaluated as well as the behaviour of N. n. in their hunting grounds. In Central Europe all females and most of the males mature at the age of about 3 months, i. e., immediately after finishing their growth. Most females older than 1 year have 2 young and the average number of young per one grown-up female is 1.8. The sex ratio at birth is 1:1 and is probably also maintained later on. The young are born from mid-June till early July and nursery co­ lonies ...
