Value of species
Formerly included in Myotis mystacinus; it was differentiated on the basis of morphology (Benda and Tsytsulina 2000).
Myotis aurascens is a western Palaearctic species; from present knowledge it is distributed in south-east Mediterranean and extending eastwards out of the region into steppe Europe, and in south-west Asia (i.e. from Italy through the Balkans to southern Russia and Transcaucasia). In parts of this area it may be the most common of the M. mystacinus group and one of most common bat species (Benda 2004).
It is a widespread species, and although common in parts of its range, this is not true everywhere. Almost all records from Turkey are based on animals caught in mist nets, usually only 1 to 2 animals (A. Karatas pers. comm. 2007).
Recorded from forest and scrub (including Mediterranean-type scrub). In Turkey it is usually caught in riparian areas (A. Karatas pers. comm. 2007). Roosts in cracks and crevices in rocks, winters in caves (K. Tsytsulina pers. comm). Forms small winter aggregations up to 15 individuals (K. Tsytsulina pers. comm.).
