This individual was among bumblebees on some bergamot flowers. It dwarfed the other bees. The abdomen was dark and faintly striped, as shown. At first I thought it was a huge bumblebee. It was so heavy that it clung upside down to the flowers. I think it might be a female Eastern Carpenter Bee. Can someone confirm the ID?
