European Woolcarder Bee Anthidium manicatum

True to its "wool carder" nickname, this bee harvests soft plant down and insect hairs to line its nesting chambers, creating insulated, woolen brood cells for its offspring. Rather than making conventional mud nests like many bees, it's a specialized fiber collector with a clever architectural approach. Found across the Megachilidae family—the leaf-cutters and mason bees—this European native demonstrates just how creative and diverse bee construction techniques truly are.
