Hello. Urophora affinis (Tephritidae) is correct? Found 19.6.2015, Slovakia, Kosice, 300m.
Thank you. Regards, Karol.

I'd say, a very pale Urophora solstitialis.

It could be even a U. affinis or U. stylata? Thank you.

U. stylata always has the 2 apical crossbands fused,
U. affinis has the stigmal crossband more or less complete and the preapical crossband lesser washed at anterior margin and the apical crossband wider separated from it; in addition, this fly has longer oviscape (in affinis it is not visible beu\yond the wings.
And the final reason: it observes a flower bud of Carduus or Cirsium, but not Centaurea (Acrolophus), the host of affinis.

Valery. Thank you very much for explanation.

In Merz (1994) it says indeed, that in U. stylata the two apical crossbands always are fused, but Smit (2010) mentions, that they are mostly fused, and I think he's right.
Every now and then I see U. stylata with very reduced wingmarkings and the apical crossbands not fused, so I think it's not very unusual.

I was looking at your site. There I see similar U.stylata to that on my photo. But I see that it's not easy to identify.
