The Serotine which is a little smaller than the previous species, has been thought to be present here but little encountered. Although said to use tree holes, it seems to occur in buildings in East Anglia. Until 1988 it was only known from the Ormesby area, but has now been found associated with buildings at Winterton and Loddon in the east, and Carbrooke and Feltwell in the west, while in Suffolk colonies are known from a school and several churches.

There is still an enormous amount to learn about the habits and distribution of these understudied and misunderstood animals and everyone is encouraged to help with this task by reporting any found or seen, and to encourage the conservation of known roosting sites.
