This is the first year I've seen these little guys, and now they're all over. Some are more yellow, some are more orange, and some are even green-ish. It doesn't show up well in the photo, but they're incredibly metallic/ iridescent. They're also pretty small. They hang out on my passionflower, cannas, hydrangeas, and wood sorrel, and they don't seem to bother anything.

My best guess is that they're a sweat bee of some sort, but they could also be flies. Anyone recognize my new little friends?
