Myotis bechsteinii

### Identification The Bechstein’s bat is the "long-eared" beauty of the *Myotis* genus. At a glance, its most striking feature is its oversized, translucent ears—measuring 22–26mm—which reach well beyond the snout when laid forward. Unlike the Brown Long-eared bat, its ears are not joined at the base. Look for a medium-sized bat (wingspan 250–300mm) with long, fluffy fur: a rich russet-brown on the back contrasting sharply with a pale, buff-grey belly. Its face is a delicate pinkish-flesh tone, and the tragus (the inner ear projection) is long, straight, and pointed like a dagger, a key diagnostic mark for the species.

### Habitat & Range This is a true specialist of ancient deciduous woodlands. It is rarely found far from "old-growth" stands of Oak and Beech across Central and Southern Europe, stretching into the Caucasus. In the UK, it is one of our rarest mammals, restricted to the southern counties. It shuns modern plantations, requiring the complex architecture of mature forests with high densities of natural tree holes and woodpecker cavities for roosting.

### Behaviour Bechstein’s are the "ghosts" of the canopy. They are highly sedentary and elusive, rarely flying in the open. They emerge late in the evening to hunt within the cluttered interior of the forest. Socially, they form "fission-fusion" societies; a maternity colony of 20–40 females will split into smaller subgroups and swap roost trees almost daily to avoid predators and parasites.

### Diet A masterful "gleaner," this bat specializes in picking prey directly off leaves and bark. While it takes moths and crane flies mid-air, it primarily uses "passive listening" to detect the faint rustle of spiders, beetles, and even flightless grasshoppers on the forest floor, hovering momentarily before snatching them with surgical precision.

### Fascinating Fact Bechstein’s bats are incredibly "loyal" to their hometowns. Research shows that female Bechstein’s are strictly philopatric—meaning they almost never leave the woodland where they were born. While males may wander, the females maintain a matrilineal dynasty in the same patch of forest for generations!
