Subject: Asian Wasp/Hornet with Orange Legs

I’m surprised I couldn’t find any reference to this wasp online as it’s a very striking insect. It was eating voraciously on these white flowers. It has long orange legs and a bluish/violet tint to its wings. There were about 6 wasps in this group feeding on this particular plant.
In our opinion, this appears to be a Spider Wasp in the family Pompilidae. There is a list of identifying features on BugGuide, and this description of the leg fits your photographs: “Slender with long and spiny legs, hind femora typically extending beyond tip of abdomen.
Tibiae of rear legs have two prominent spines at apex (distal end, next to tarsi).”
Spider Wasps often visit flowers in search of nectar, and female Spider Wasps prey upon Spiders to provide food for her brood.
