bristly airborne piglet

a good weekend at this spot, during which I found 3 very tiny Chrysotoxum on a single thistle, one of which very fresh and wrapped lightly in web, so I have my first 'voucher' specimen. Only slightly darkened (nectar perhaps), it was quite 'relaxed', I've photoed it and it's now in the freezer in tissue in a macthbox, I'm not hugely sure what to do next.
The other two displayed their sternites nicely, and all three show the curving bands described by Stubbs for verralli, plus their absurdly small size.. I was hoping to put them up as a species?

.. all rounded off by this mini-monster, which seemed like a smaller version of one you described just the other day. (It didn't quite end there, I had to cut through the park to get home and there was my first Scaeva p. waiting for me, hovering beautifully but I messed up my one chance when it briefly settled!)

Specimen

I suppose the next step is that you pin the specimen and keep it for future reference. If that sounds like a direction you might take, and I recommend it if you want properly to get to grips with the flies of your local site, then some tips are found here...

It was Chris Raper who confirmed your Nowickia after I suggested it, on Diptera. info. His advice is well worth following.

Good luck!

pinning or bottling

yes thanks, I wondered if pinning or keeping it in solution was best.

I like the idea of pinning from the side with a micro-pin. I had been looking at relaxing fluid etc anyway and found a site that sells it, so I'll have to figure out if I actually need it, though I expect I'll foul this one up anyway as it's my first one

Pinning

When you take it out of the freezer, it will be relaxed for while, so as long as you pin it fairly quickly, it will be fine and you can position the legs as you want...etc. Relaxing fluid would only be needed if you left it overnight, say, by which time it would have gone hard. I never use relaxing fluid at all.

Distribution

Ah...I wonder why? If you look at the NBN map, above, you'll see the UK distribution, which is mostly southern.
