On the same flowering plant as Valley Carpenter Bees. No interactions between the two.
Saw it on lavender plants outside of the GW Psychology Dept. building.
Fairly large, fuzzy fly, sitting on a porch. It appeared possibly injured, as it wasn't trying/able to fly away, when I approached, and seemed to be almost limping around/restricted in motion.
A bumblebee is any member of the bee genus Bombus, in the family Apidae. There are over 250 known species, existing primarily in the Northern Hemisphere although they also occur in South America. They have been introduced to New Zealand and the Australian state of Tasmania.
