Nyctalus commonis is close in size to the greater Nyctalus, and hence also the difficulty in relating to past information about the two species. The species is in critical danger of extinction in Israel. The species is known from only a few sites in the north of the country, with only a few dozen individuals, and has also been observed on Mount Hermon. In the past it was abundant, as its name indicates, and it is therefore mentioned in our sources as common among the members of its genus.
