Can anyone confirm that this large pale coloured Tabanid with psychedelic green eyes is Philipomyia aprica? 16.7.09 Lower Anso valley, Spanish Pyrenees. Nick Upton nick upton attached the following image:  [125.52Kb] Edited by nick upton on 27-11-2010 16:28 |

I doubt it - Philipomyia aprica is very dark. |

Thanks Phil. Might it be P. graeca then which looks paler and is known in the Pyrenees according to one report? Nick |

Many thanks Lukasz. Now I've found some photos of Silvius, I can see you are absolutely right, but I can't find much information online to know what species this might be in the Spanish Pyrenees (not very high, maybe 800m). The only spanish record/photo I have found is for Silvius alpina (also known as Silvius vituli) and it looks just right, but I don't know if there are other, similar species it could be. Maybe someone can help? Nick |

There are two very similar yellowish Silvius species: S. alpinus and S. algirus. According my knowledge, S. algirus is not known from Spain. I did not see this species, so I cannot solve with certainity ID of this animal, but probably Silvius alpinus. Libor |

Many thanks for your advice Libor. I can't find any S. algirus records in Spain on the internet, either, so this probably is Silvius alpinus based on the information I have now. Nick |
