got one

it's ok, I just nipped out and got another one, now in the freezer. It's smaller than this one, also orange-ish, more noticeably 'waisted', a yellow line running a clear half only along the edge of the thorax, and pale antennae I think

Have been encouraged to collect Cheilosia, Sphaerophoria, Pipizines, and Syrphines before the season ends

Sphaerophoria

Nice!

They are a good one to start looking at...the genitalia take a bit of getting used to, but once you get the hang of it, you can do some of them OK. 'Hoverflies of Northwest Europe' by van Veen is worth getting hold of, if you don't have it...has some useful pics of these.

Some of the smaller flies are beginning to dry up, at least for me up here, so grab all you can in the next couple of weeks.

Smart fly, but a shame it was a female...you need to find another male!

females?

I think the one I've just caught (added) is a female, doesn't that make it nigh on impossible? Less 'waisted' than I thought at first too, it was mainly the broken yellow thoracic line I looked for before deciding to keep it

Yes, you need to find another male, or, ideally, a pair in cop. These small species of Sphaerophoria seem to have had a bad year on my local site...very thin on the ground compared to normal summers.

yellow stripes

I wondered if there was a chance of narrowing this down at least, given the stripes which seem only to extend half-way along the edge of the thorax

Stripe

Looking purely at the male (first picture), you could be right with rueppellii, but you'd need to look at the genitalia to be sure, I would think. It does seem to have pale antennae and legs, and apparently the Thames estuary is a favourite place. Not a species I know. Other species can lack the full yellow stripe, including fatarum, the commonest small species on heathland near to me.
