Not Dexiosoma

Certainly not D. caninum - I claim no great competence with bristly jobs but this looks more like a Muscid/Sarcophagid to me. D. caninum is a lot narrower and more olive-brown.

Fly

It was its persistent exploratory behaviour that ciught my attention. I was doubtful re Dexiosoma - which is said to be parasitic on cockchafers and I have never seen one of these on site.

Sturmia bella

Thanks. Interesting. Parasitoid on the Small Tortoiseshell's larvae I gather.

It isn't specific to ST but

It isn't specific to ST but they are the commonest host in our region. They have been reared from Peacock and also (surprisingly) from Speckled Wood, once. Just don't believe the hype that they are responsible for the decline of ST because it isn't the case - humans have been creating the conditions for species decline for the last 60-70 years and Sturmia came in very late in the day ;) They range across the northern hemisphere from western Europe to the orient and have never been considered an issue there.
