Here is another view of the same wasp. Its face was yellow, which I think means that it is a male.
Another insect I found yesterday was this weevil, which is crawling through Sedum flowers. There are numerous species of weevils, and I am not sure which one this is, or even what its genus is. Curculionidae is one of the largest of all animal families, with over 40,000 species worldwide and 2,500 species in North America. If you are familiar with Sedum, you can get a sense of just how tiny this weevil is. It seems dwarfed by the flowers, which themselves are pretty small.
