Cute Carpenter Bee (?) on Tarweed
Hayfield tarweed (Hemizonia congesta ssp. luzulifolia). The tarweed is out today. Thanks to Pierre Martineau, who writes: "I think you'd like to know that the "iridescent fly" (images 3-7...) is actually a bee; I believe it is a species of Ceratina, a genus of (cute) small carpenter bees."
