What action gives the Wool Carder Bee its common name related to female behavior?

Answer

Deliberately scraping fine hairs from plant leaves for brood cell lining

The common name 'Wool Carder Bee' is directly derived from the unique nesting behavior exhibited by the female of the species. After mating, the female diligently seeks out specific plants that possess fine, fuzzy hairs or fibers on their leaves and stems. She then uses specialized scraping motions to gather these plant materials. These collected fibers are meticulously packed around the developing larval chamber to create a soft, insulating envelope for the egg and its provisions. This process of collecting and packing fibrous material is analogous to the historical process of 'carding' wool to prepare it for spinning.
