Italy : Near Threatened - NT ( Rondinini et al. , 2013 ). This is one of the most common bat species in the study area, detected in 32.0% of kilometric cells in the study area up to an altitude of 2000 m . A temporary roost used by 1-2 individuals was located under the roof of a residential building in Palanfrè (Vernante) during summer 2011 at 1450 m a.s.l. Ten individuals ( 5 males and 5 females ) were captured nearby waterways in the Gesso valley . Although breeding sites were not identified, post-lactating females were captured, indi- cating that the species probably reproduces within the study area .
