Found feeding on Oenanthe crocata in Madrid mountains on 12.06.2014. Any ideas?? Thanks a lot!! :)

Pity we can't see the antenna properly.
Looks like a Dexiini, and given the ad-row on tibia 3 one minds goes to the genus Billaea.
Without being sure on the genus, I amnot going to speculate at species level.

Well, it certainly looks like a Sarc at first glance.
However, the lack of bristles on the parafacial and the mentioned comb on tibia 3 makes this unlikely. If it is a Sarc, it is definitely a special one.

Yes, fully agree. I replied too fast. The head shape didn't convince me too. And in photo 3 the subscutellum seems too prominent for a typical fleshfly.

Theo, Valerio, thanks a lot!! :)

My own thoughts ;) : I also thought of Sarcophagidae but I ruled it out by the shape of median vein. And I also thought of Billaea but not because I have much knowledge but because this seems to be a good year for Billaea and I see too many similarities with the ones I have already photographed this year. This would be the first female I see ;)

Theo, if the antennae are of any hep I can try to rescue a detail of them ;) Won't be a great picture but if it is of any interest it will be worth the effort :D

I need to be able to estimate the length of hairs on arista vs. width of third antennal segment. If you can make that happen.......

And yet, it moght still be an Estheria with open topcel.
Those exist.
Need to work on that.

Theo is right, this is not a flesh fly, and to me it looks like Tachinidae. There are similarities to Sarcophagidae, like the checkered abdominal pattern, and the stripes on thorax, but note that the stripes are not the typical three black stripes. Also, you can actually just see the swollen subscutellum on one of the photos.
