In researching this black wasp on my deck sedum, it looks like a Potter Wasp. There are a variety of Potter Wasps in North America. Those in the genus Euodynerus look similar to each other, with some species requiring close inspection to differentiate. Black bodies have a short yellow band above the waist on the thorax. Usually they will leave you alone if you don’t invade their space. I kept my distance with my camera. More amazing little critters in my deck garden.
