A relatively small bat species (body length about 4.8 cm, weight about 8 g), found in southern and central Europe, with a distribution extending in a fragmented manner to Turkestan and also reported from Morocco. At the bottom of the page there is a link to its discovery in 2012 in England.
In Israel, Geoffroy's bat is a bat that inhabits deep, damp caves in the Mediterranean region. The Hebrew name comes from the distinctive structure of the pinna: a small notch can be seen at the edge of the ear. The species is in grave danger of extinction. While today it is known only from a few sites in the north of the country and in northern Samaria, in the past relatively large colonies were seen at many additional sites including Mount Carmel (Tristram, 1884).
