Grey long-eared bats are very rare, medium sized bats found only in a few places in southern England. It can be very difficult to distinguish the rare grey long-eared from the more common brown long-eared bat (Plecotus auritus). However, the inner earlobe (tragus) is wider and its thumbs are shorter. Grey long-eared bats tend to forage over meadows, grasslands, gardens and near forest edges.
