It forages over scrub and grassland. It has an unusual diet in that it feeds mainly on spiders and flies. In summer, it roosts in underground habitats and in buildings (in attics). Generally roosts in summer with Rhinolophus species. It winters in underground sites. In Iran and the Caucasus, the species occurs in a variety of habitats, but in low numbers (M. Sharifi pers. comm. 2005). Reportedly a sedentary species with movements of up to 105 km recorded (Schunger et al. 2004 in Hutterer et al. 2005), but may in fact move longer distances as winter roosts are not known in parts of its range where it occurs in summer.
