Yes, it is a female Tachina. Normally, I'd say it is T. fera, but I can't rule out casta. Theo |

It is the species which I collect still in October November, at the moment never before. The first intra-alar postsuturale bristle seems absent, the marginal median bristles on tergites 4 are numerous, on the tergite 3 it is not the case (?). I find it close to Tachina casta. I had made a thread on this species http://www.dipter...d_id=44071 Edited by christoophe on 16-11-2014 20:17 |

Christoophe, You are right. This is not fera, but more something like casta. And there is another 'ghost' species I have never seen, I think it is called corsicana. Theo |

Ok, I'll put it down as Tachina cf. casta so. Unless I am labelling that incorrectly. My list for the Italian mainland is below, could be inaccurate I suppose but I am guessing corsicana is endemic to Corsica ? Tachina casta (Rondani, 1859) Tachina fera (Linnaeus, 1761) Tachina grossa (Linnaeus, 1758) Tachina lurida (Fabricius, 1781) Tachina magna (Giglio-Tos, 1890) Tachina magnicornis (Zetterstedt, 1844) Tachina nigrohirta (Stein, 1924) Tachina nupta (Rondani, 1859) Tachina praeceps Meigen, 1824 Tachina ursina Meigen, 1824 source. http://www.faunaeur.org/species_list.php Thanks for the help Theo/Christoophe |

The reddish margin of scutum and red parts on pleuron are a clear feature of T. casta (see Cerretti, if you can read Italian), not corsicana. Latter, by the way, restricted to Sardinia in Italy (loc. cit.). So casta it is ! Theo |
