long-eared bat (Plecotus
auritus) This bat has strikingly big ears, which together with the broad wings allow a slow and successful foraging flight even when manœuvring through dense vegetation. Long-eared bats mainly hunt or moths, including forest pests such as the gipsy moth and green oak tortrix. |

Colonies of females - so-called
nursery colonies - are found in tree holes, sometimes quite small, with
free access or covered by foliage. Accidental findings in cut trees reveal
that now and then tree holes are used as winter shelters as well.
