Small wasp, distinctive markings yellow/black. Nectaring on heuchera, then sat on leaf.
No interactions present.
You might be interested in this observation of a similar mason wasp as I've included a picture of the hoverfly that imitates them (pic 4)
- right down to the dark wings and yellow corners on the thorax, and the leg colours. Amazing.
..sorry I can't agree yet I'm not familiar with this genus
