Pollen Wasp

This big and mellow wasp just wants to eat and pollinate. Each Spring, I find them sleeping inside our Penstemon flowers in our field as seen in the last image. This female (shorter and non arching antenna) didn't care I was taking photo's of her. She has dark wings and ends of the clubbed antenna. The abdomen is yellow with black stripes across the tops of almost each segment. There are black spots on the top centers of the segments at the black bands. Small black spots are along the sides of the abdomen at each segment The scutum is black with two yellow crescent marks toward the back center. The head has a yellow band running under each eye and across the frons. There is also yellow on the clypeus and scutellum although not all of it.
