Which bee family is known for carrying pollen on the underside of the abdomen?

• A. Colletidae (Plaster Bees)
• B. Apidae (Bees)
• C. Megachilidae (Leaf Cutter Bees)
• D. Halictidae (Alkali Bees)

Answer: (C)

Pollen transport methods reflect how bees provision their nests. The family that uses a specialized patch of hairs on the underside of the abdomen, called a scopa, to carry pollen is the group that includes leaf cutter bees. This ventral abdominal scopa means pollen is collected and held on the underside of the abdomen rather than on the hind legs. It’s a distinctive adaptation tied to how these bees nest—often in cavities where they pack pollen directly onto brood cells from the bottom side of the body.

This is why leaf cutter bees are the best answer: their pollen-carrying strategy is defined by abdominal, not leg-based, pollen collection. Other bee families typically store pollen on hind-leg structures (pollen baskets) or on other body hairs, so they don’t carry pollen on the underside of the abdomen.
