I went out into the back yard this evening to see what I could find. There was a serious buzz around the flowers with dozens (or possibly hundreds, I really don’t know) of bees, wasps, skippers, and flies all moving about. After getting a few pictures of a wasp on the mountain mint, most of which are pretty blurry, I went to see what was happening at the buddleia near the gate. This potter wasp (Eumenes fraternus) flew up to the top branches but I could see it was carrying something. Turns out it has a caterpillar. The female potter wasp lays eggs in a mud nest and then provisions it with small caterpillars, as food for the larva.
