Dianthidium M & F

Thanks so much for identifying these dianthidium bees. They are the first I have photographed, although in California I have seen and photographed some beautiful pebbled dianthidium nests. Your help is so much appreciated.

Dianthidium

Thanks for your suggestion. I was hoping they were dianthidium--and they were!
