The Savi's pipistrelle has a Palearctic distribution pattern (Horácek and Benda 2004, Wilson and Reeder 2005), with Israel marking its southern boundary. The species is known from northern Israel: it has been observed near settlements in the Upper Galilee and caught in the Hermon. It was probably also recorded at more southern sites, including the Shephelah, but the information is still under review and has not yet been confirmed. There is almost no information about the species' preferred roosting sites in Israel, except that it was found roosting in a natural crevice in a canyon stream in the Upper Galilee.  

The fur pattern is variable:
While the individual in the attached photograph from northern Israel has a very contrasting pattern, it is sometimes darker and more uniform (as can be seen in photographs from the ARKive website)

Frequency: 36-38 (50-32) kh
