I know this is probably unanswerable, but is it possible to suggest a species for this male Gymnosoma? I wondered about clavatum, but it's just a guess. Photo taken today in my orchard, central lowland France, about 7mm.

Hmm, with a continuous line of dusting to the tip of the scutellum then I'd make it dolycoridis or desertorum but I'd also need to see genitalia to elliminate clavatum  Best thing to do is to catch them - lots of them - and then we will know better.

I knew you'd say that  I thought afterwards I should have caught to send to you or Theo, but I didn't have anything except the camera (and a bucket for collecting nuts) with me. This is the first one I've seen in the orchard. I'll try to do better next time

Well, my door is always open to tachinid donations!  Gymnosoma are always a bit nasty though so I wouldn't promise a confident ID ... but a male clavatum would have been easy to say yes/no to from genitalia

Even clavatum is not always easy.... don't underestimate the problems. This might very well have been clavatum Theo |

Yes, peering at his genitalia and looking for a light lump is not easy - especially as they are normally hidden amongst the back legs
