The Georgia mason is one of several species of mason bees (Osmia spp.) in Missouri. Like other megachilid bees, it is a native solitary bee that is an important pollinator. The body is black with a bluish or turquoise metallic sheen. Like other members of the megachilid family, females carry pollen on the underside of the abdomen, within a special clump of hairs called a scopa or pollen brush. In this species, the scopa and other hairs are noticeably pale, yellowish, or whitish. The megachilid bees are the only group of bees that have a scopa for carrying pollen. When full of pollen, the underside of the abdomen therefore looks bright yellow or orange. They do not carry pollen in baskets on their legs.
