Rare soldier-fly doing well at its English site. Female and male shown.
No interactions present.
looks like you've found a good spot or area for these. Not seen any of this sub-family myself yet. I noticed you've described this as large, my first Pachygaster a fortnight ago were a bit underwhelming, though nice enough through a macro lens.
Nothing moving here under the heat except the odd Chloromyia and some common tachinids, a useful break if only it were cool enough to do anything else

This fly is only found here and at one spot in Wales...a real rarity! Incredible that a fly can exist in so restricted an area...it's been hunted for elsewhere in similar habitat, but no joy, yet. Makes you wonder what else is clinging on in isolated areas, yet to be found...
As for size, smaller than Stratiomys potamida, but larger than Sargus/Chloromyia, for example...
Agree about the weather...just been out from 8am - 9.30am, but not much around, really (though a few potted up for later).
