Another Tephritid Fly

A female Urophora quadrifasciata (Diptera: Tephritidae) on knapweed (Centaurea sp). 

With a wing length of only 2.5mm, these flies are noticably smaller than most other Tephritid flies.

Your Lauxanid is I think Palloptera arcuata - thgere is no Lauxanid with this sort of wing pattern

Thanks again Roger. I did think the fly (shown here: http://tristram.squarespace.com/home/2012/6/26/yellow-fly.html )was a bit 'clean' for a Minettia inusta but I was in a hurry and obviously didn't check it as closely as I should have.
The UK Checklist has Palloptera arcuata down as a synonym of Palloptera quinquemaculata.
