When I first saw these two damselflies from afar I assumed they were mating (en flagrante delicto), but upon closer examination, they weren’t (more en flagrante delicio). Damselfly on the left is probably in the genus Enallagma, but I’m happy to be corrected if you disagree. I’m also unsure of what who the dinner is.
