es. It locates its insect prey via echolocation. The frequencies used by this bat species for echolocation lie between 18–45 kHz, have most energy at 28 kHz and have an average duration of 5.8 ms.


Distribution

Distributed throughout all of Europe, except for the Scandinavian Peninsula.


Conservation

It is currently listed as near-threatened by the IUCN. It has a large geographic range and it is considered relatively common. In most of the countries where it is found, it is protected from intentional harm by legislation. While Continental European distributions are not threatened, a 2013 study found this species was close to extinction in the United Kingdom. One possible reason for its decline in the UK is the loss of foraging habitat. It is currently a focus within the Back from the Brink conservation project which aims to increase foraging habitat around known roost sites. This species may also be threatened by

. One researcher noted, "long-lived, slow-reproducing species with smaller population sizes are not likely to be able to adapt to future climate change fast enough through the spread of new mutations arising in the population." In the future, it may be necessary for humans to relocate bats to suitable areas as climate changes.
