pedissequum

I reckon you are probably right, but the pleura cannot be seen properly in the photos, so hard to be sure.

spots and other things

yes, looking even closer at picture 2 I can see it's the dark of the wing across that area, not a lack of spots. But it's one of several features to check anyway, as you've pointed out before.
I'm doing searches to try and see if anyone's actually found UK dives or stackelbergi and if so where, it would seem a useful starting point

stackelbergi

According to Alan Stubbs article in Dipterists Forum Bulletin Spring 2012, no records of dives are known of in the UK (but it could occur?).

In Dipterists Digest Vol 19.1, he lists specimens of stackelbergi from his own collection. A male from Northamptonshire in 2001, and four females, from Kent, Surrey and Berkshire (all found in July).

He gives stackelbergi as a woodland species, woodland edges and rides worth a look. pedissequum he gives as a grassland species more.

strictly grassland

ok, I've only found them in open-ish scrubby grassland/parks so far, with a maximum of two extra spots. July. I'll be on the lookout in Glos. (weather permitting) this week then, perhaps where I found v. inflata.. not wettish woods, I'm guessing
(sorry to name-drop species you may not see where you are)
