barbastelle

The barbastelle is a species of bat belonging to the family Vespertilionidae. It is found across Europe and parts of Asia. There are two recognized subspecies: Barbastella barbastellus and Barbastella leucomelas. These bats are characterized by their distinctive flattened snout and broad ears, which give them a somewhat snub-nosed appearance.

Barbastelles are primarily nocturnal insectivores, feeding on a variety of flying insects such as moths, beetles, and flies. They are known for their agile flight and their ability to navigate dense woodland environments. Their echolocation calls are typically in the ultrasonic range, often at lower frequencies than many other bat species, which may help them detect insects against background noise.

These bats typically roost in tree hollows, crevices in rocks, or old buildings. They are often found in mature forests, deciduous woodlands, and mixed woodland habitats. Barbastelles are solitary roosters, though they may gather in small groups during the mating season. They are generally considered to be sensitive to habitat disturbance and fragmentation, making them a species of conservation concern in some regions. Their conservation status varies depending on the specific population and region.
