Insect and Spider Identification: CLOSED: A little metallic green bee, I think, 1 by DrDoolotz

I saw this "bee" on my Monarda. I think it is a bee because it was collecting pollen, and its back legs had yellow "saddlebags" of pollen on them, just like a regular bumblebee. But this bee was very tiny, and as you can see from the photo, it is metallic green in color. I have never seen a bee like this before. Maybe it is not a bee and just another bug that carries pollen on its back legs. Sorry for the photo being so out of focus - I had to take it in a hurry. It was a busy bee/bug.

Oh, I live in Iowa, zone 5a. Therefore it must be an insect we normally have around here, I would think.

Thanks for any ID!
