These bats forage over a wide area often coming out whilst it is still light to forage in dark areas of woodland, coming out of the woodland to feed as it get darker. There are reports of the bats in North Norfolk and west of East Dereham but these rare bats are difficult to find.
There are few sightings of colonies in the UK and most of the sightings have been of single bats in underground sites. They are known to roost in cavities behind joists of wooden buildings and occasionally behind loose bark on trees.
They prefer pastoral landscapes with deciduous woodland, wet meadows and areas of water such as streams and rivers and the Norfolk Bat Survey have identified them feeding in the Claylands Living Landscape close to Hethersett and Hempnall during August and September.
