Eumenes fraternus (Potter Wasp)
I see these fairly often but this is the first time I’ve gotten a decent picture of one. This is on the tiny red flowers of painter’s palette (Persicaria virginiana) in our back yard. it’s also one of the first good pictures I’ve taken of these little flowers, now that I think about it. They really are small but add a red haze over the variegated foliage.
