What part of the carpenter bee lacks the characteristic bee hairs?

The abdomen is the part of the carpenter bee that lacks the characteristic bee hairs, which are commonly found on other parts of the body such as the head, wings, and legs.

Carpenter bees have a unique physical characteristic where their abdomens are typically smooth and shiny, rather than being covered in dense hairs. This lack of hairs on the abdomen distinguishes them from other bee species that rely on these hairs for pollen collection. The hairs on the head, wings, and legs are vital for foraging and pollination, facilitating the attachment of pollen grains as they move from flower to flower. By focusing on the abdomen, it becomes evident that these bees have adapted differently, prioritizing other anatomical structures for their survival and reproductive behaviors.
