Also in south-west of Holland (Glas, pers. comm.,
Voûte, pers. comm. 3/1982).

World: NE Europe and W Siberia, NE France and Germany, east to
River Yenisey. It is found between latitudes 48-60°N. In
eastern Europe and western Siberia, the scarcity of records
makes it difficult to assess numbers and distribution. The
species is known to migrate (Horkek, pers. comm., Sluiter et
al. 1972, via Horkek, pers. comm.).
Prefers riparian habitats and usually feeds over waterways
(197). It roosts in buildings in summer and caves, mines and
cellars in winter. Nursery roosts and hibernacula are often
200-300 km apart.
