I wouldn't like to say which Tachina spp. it is - the base colour is either very dark or the photo has too much contrast perhaps? |

In simple terms the 2 species are split using the colour of the fore tarsus and the frons/eye ratio. The problem is that these are very hard to tell from the photo but the fore tarsus does look very dark, which *might* suggest magnicornis. BUT (and this is a big but!) you are assuming this is either fera or magnicornis, but I think in southern Europe there are other species. |

Oh, sorry. I supposed that there are only these two species with these coloration, but clearly can be any other species. I'm completely new in Dipterans, excuse my big error! |

No problem  The Central European key (Tschorsnig & Herting, 1994) is a good starting point with tachinids but it is only accurate in north/central Europe. In Spain you might have to consult local literature and perhaps discuss this with Spanish dipterists to get a more complete picture To download my English translation of the Central European key visit this link: http://tachinidae...nloads.php |
