Zwergfledermaus

<em>Pipistrellus pipistrellus</em>, the common pipistrelle, is a small bat in the family Vespertilionidae and one of the most abundant and widespread bat species in Europe. It is typically one of the first bats to emerge at dusk, flying with rapid, jerky wingbeats as it pursues small flying insects over gardens, woodland edges, water bodies, and urban areas. The species roosts in crevices in buildings, bat boxes, and tree holes, often forming large maternity colonies in summer. <em>Pipistrellus pipistrellus</em> echolocates at a characteristic frequency of around 45 kHz, which allows it to be identified using bat detectors. It is distributed across Europe, with confirmed records from Belgium, Denmark, Luxembourg, Norway, and Portugal, among many other countries. The species is assessed as Vulnerable on the IUCN Red List, reflecting population declines driven by loss of foraging habitat, reduction in insect prey biomass, disturbance of roost sites, and pesticide use. Biological traits such as average lifespan, body size, weight, and detailed dietary composition across its range remain poorly documented in the scientific literature, though the species is known to consume large numbers of small moths, midges, and other aerial insects each night.
