Rhyssa persuasoria?

Don’t know if there are any similar species in the UK.

Certainly not Rhyssa as no mesocutal ridges or white metasomal spots of persuasoria.
There are many species like this in UK, but most are rather small. This could be Dolichomitus or Paraperithonus or several other genera in the Pimplinae.

Thanks Ficedula

Are they ever identifiable from a photo or do I need to catch one and look for particular features (not that I would know what I was looking for) ?

Many are by experts, I'm not so am reluctant to name them without a specimen. If you don't want to take specimens you can pot them, cool in fridge and then photgraph. You often need shots from several angles including wing venation, detail of propodium and face. There is an excellent FB group where a few experts might comment on your photos.

Thanks Ficedula. I've nothing against taking specimens but I'll probably give the refrigeration a go - if I manage to find some more insects.

I have many pots of dragonfly exuviae that need IDing / Cataloging etc. before I start a diptera collection!
