Anthidium Opacum

Please note that the content of this book primarily consists of articles available from Wikipedia or other free sources online. Anthidium opacum is a species of bee in the family Megachilidae, the leaf-cutter, carder, or mason bees.The Megachilidae are a cosmopolitan family of (mostly) solitary bees whose pollen-carrying structure (called a scopa) is restricted to the ventral surface of the abdomen (rather than mostly or exclusively on the hind legs as in other bee families). Megachilid genera are most commonly known as mason bees and leafcutter bees, reflecting the materials they build their nest cells from (soil or leaves, respectively); a few collect plant or animal hairs and fibers, and are called carder bees.
