I was having a terrible time attempting to key one of these to genus using Wood's 1987 tachinid key. This would explain it!

Moved from Flies.

Do you have a picture from above and behind showing whether there is a subscutellum? I can't place this as a Tachinidae. (Characters: strong crossed apical scutellars, strong divergent lateral scutellars, basal scutellars reduced to hairs, no discals, eyes bare, prealar weak, outer verticals absent, parafacial with scattered hairs but no row of bristles, M meeting R4+5 well before wing margin, costal spine strong.) It reminds me of Stevenia, with some differences from the deceptoria we have in the guide (parafrontal strips wider, pollinose areas on thorax smaller).

I posted an image (poor quality)
taken through the vial with a scope. I think it shows a subscutellum.

Unfortunately no
I posted another lateral that shows a hint of something under there. Not sure if that is a subscutellum or not.

I'm asking for expert advice. I suspect a dark Stevenia deceptoria.

Thanks John
I bet you are right. Looks like a common species in Europe with lots of photos available and many are nearly all black.
