Bugman, the wasps and bees really like this particular hemlock weed with many colorful varieties visiting it today. Looks like a Metallic Sweat Bee, a Digger Wasp, and one other black/white wasp. Would the black wasp with white bands possibly be a type of Mason Wasp?

Generally we don’t like making postings with diverse insects, but all your pollinators are in the order Hymenoptera, and they are all visiting the same blossoms for the same reason, to feed on nectar, so we are making an exception. We agree with your identifications of the Metallic Sweat Bee which looks very much like this image on BugGuide, and the Digger Wasp, Scolia dubia.
The third wasp is most likely a Potter Wasp and we believe it is in the genus Eumenes, which you can find pictured on BugGuide, however, we were not able to confirm a species identification.
