Scarce swallowtail, "Scabius" flower and Polistine wasp. "I was taking pictures of scarce swallowtails on Scabius flowers when I heard a Polistine wasp buzzing around - It was hovering behind the butterflies and then darting in and body-checking them. Although I didn't witness predation I later saw a wasp dismembering a skipper in the same area. I’m pretty sure this wasp was trying to predate the swallowtail. I like the picture because it was difficult to take - the wasp was moving very fast and the focal plane was very shallow - and because it captures three trophic levels in one."
