Could someone help me identifying this Terellia? Perhaps serratulae?
The photos (author: Rosa Angulo) were made near Madrid, Spain, on 6.8.2011. I upload photos of a female and a male.
Thanks.

The male...

I was with Rosa and took pictures of the same specimens. They were everywhere on those thistles. My best shot is of this female. Hope it helps.

Thank you, Piluca;
I think it can be Terellia (Terellia) serratulae.
:-)

Oviscapo doesn't seem to be long enough for T. longicauda, neither I see the bluish colour. But it is that way to my unexperienced eyes ;) I guess other opinions are necessary. Let's see if Valery can put some light to this mystery :)

Thanks, Piluca!
Perhaps this fly can only be identified as Terellia sp.

I'ld say Terellia longicauda, the oviscapus is too long for T. serratulae and the third antennal segment is not black, hence no T. fuscicornis, which leaves us with T. longicauda.

Still there is "something like T. longicauda" in Spain (incl. Canaries) that infests artichoques. Bernhard Merz recorded it from Canaries as T. sp. nr fuscicornis, but I still do not know what it is, though have gathered quite a lot of stuff from several European collections.

Since the plant is certainly not an artichoque, but a Cirsium (apparently C. erisithales), yes, it is almost certainly T. longicauda.

Thank you very much, John and Valery!!
