This nice female tephritid was yesterday at La Peña, Huesca, NE Spain at 500 meters. Host plant: Onopordum sp. Could it be identified?   Thanks, Isidro |

Thanks Valery, but I had this other fly as U. terebrans... http://www.diptera.info/forum/viewthread.php?forum_id=5&thread_id=15692 With wings much strongly marked, one more band at the basis... and a much higher level, more than 2000 meters while this one is at 500 only... |

After so long time (and unresolved thread in Diptera.info) the image of the thread have disappeared. This is the supposed U. terebrans from Panticosa: What characters are needed for be sure on the species terebrans? |

Dear Isidro, I said: "possibly" terebrans. This means that Urophora terebrans, U. solstitialis, U. cuspidata and some other species cannot be IDed with certainty without seeing the tip of female aculeus (ovipositor blade) tip under high magnification, plus ratio of aculeus/wing length. They are similarly variable from dark pattern as on the third picture to narrow and pale, as on the first two pictures, depending on the environmental conditions. In your case, the only chance to say, what it is is the host plant, however, flies can visit improper plants from time to time. In your case, I also made a mistake, when considered brown strikes on wing as rudiments of the subbasal crossband. As I see now, the second picture does not show this strike at all, and this coul be only the knees of the fly under the wing. In this case, wing pattern and entirely reddish yellow femora are typical for one species only: Urophora stylata F., which is associated with different species of Cirsium thistles.
