PHOTO COMMENT
These are common bees that are mostly black, but may have brilliant tones. The thorax and legs are covered with fine setae (hairs). Adult females overwinter in the pith (soft center) of stems that are exposed by pruning, breaks or burns. In the spring females excavate further, turning their winter chamber into a brood nest. Nests are provisioned with pollen. Pollen stores are fed upon by both the developing brood and adult.
