Cute Carpenter Bee (?) on Tarweed (Detail)
You can see the three eyes on the forehead, as well as the large compound eyes. Many insects and plants are hairy at this scale. 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."
