Not sure what sort of bug this is. Looks like a beetle but has an abdomen like a wasp. At any rate it was a very busy critter on the Black Eyed Susan’s after I watered them.
@casablanca Turns out that this is a soldier beetle. Though it looks a little wasp like it is harmless to humans. They don't bite and they don't sting. They are prolific pollinators so I will not disturb them when I see them at work on the flowers.
