I'm not sure you can call this "action" but here's a male Peponapis pruinosa squash bee in a Morning Glory flower. Typically they sleep in squash flowers, the females visit those flowers at or before dawn and the males camp out. I suppose a Morning Glory has a close enough shape for Mr. Squash Bee.
First time documented at the James Woodworth Prairie, but likely they've been around the neighborhood.
Another first at JWP, this Anthidiellum notatum is nectaring on mountain mint. They're a common enough bee across all of North America.
This isn't a great shot of her, but you can see the pollen-transporting scopa hairs on her underside. You can also see one of the ever-present Chalcid Wasps to the right. These lay their eggs on the eggs of other insects.
