Hello,

I started checking the collection of Joseph Bergerard, a French entomologist. There are quite a few Haematopota, including one that could be something other than pluvialis. Particularly with the grayer tint than the other specimens and a less pronounced constriction of the first article of the antenna. But maybe I'm wrong ! So I create a post to be sure.
1987, in north Brittany, near littoral.

and subgenital plate.
The upper part appears rolled up. If so, we could have the same shape as pluvialis.

and a bad view of the frons, maybe too grey for pluvialis ?
If I compare the first antennal segment with photos from internet I think it's pluvialis. subcylindrica, which is a potential candidat for my specimen, have this first antennal segment more regular, less misshapen.

Appréciation of colour is quite difficult but maybe with when I will see lots of spécimens it will be easier
