These two flies were flying around one on top of the other, and they eventually landed on a plant.
I am not particularly curious of the species. I just wanted to send you this for the Bug Love section.
Our hunch was that these were mating Tachinid Flies, and upon doing some research, we found we are correct. We initially identified them as Ectophasia crassipennis on the Insects of France website where we learned: “This fly lives in southern Europe and in the warm parts of Central Europe. Not in the Netherlands like some other members of the subfamily. … Males and females are different. The brownish yellow abdomen of the male has a wide black stripe. The female lays the eggs directly into the host the shield bug (Pentatomidae) Length 5 – 9 mm. May – September.” We verified the identification on another French site.
