Ynghylch

Formerly a cave-dweller, the greater horseshoe bat now tends to roost in old houses, churches and barns. All UK bats are nocturnal, feeding on midges, moths and other flying insects that they find in the dark by using echolocation. In early summer, greater horseshoe bats will emerge at dusk and dawn, however, preferring to roost through the middle of the night. From May, females form maternity colonies to have their pups. Greater horseshoe bats hibernate over the winter in caves, disused mines, tunnels and cellars.

Greater horseshoe bats often choose a regular perch in a tree or cave from which they can watch for passing insects; when they spot their prey, they fly out to catch it in the air. Insect remains beneath such perches can be spotted in spring and autumn, in particular.
