While honey bees have pollen baskets (corbiculae) in which to carry pollen back to the hive, many native bees carry pollen on the underside of the abdomen instead. The abdomens of these bees are covered with a thick tuft of elongated hairs called a scopa. Instead of packing the pollen into a ball, the pollen is spread over the entire abdominal area. The photo below shows an unidentified bee climbing into her nest. Just her backside and scopa are visible, covered with bright yellow pollen. Notice there is no pollen basket on her rear leg.
