do you agree with Thereva sp. ? I?m waiting for confirmation. I sent an email to an expert of Therevidae family.. I hope that is possible to get species level.

Yeees, but I'm hardly a therevidologist  This is another family with waay more species in the Medterranean area than in the boreal zone.

I agree, but then again, spotted wings are quite queer for Thereva, it suggests Dialineura.... ?? Theo |

What? Several Thereva species have more or less clear spots around crossveins.

jorege, and other future Therevid photographers, Please take facial shots at these creatures, since they are usually required for the proper identification of Therevid flies. Gabor Keresztes Japan Wildlife Gallery Carpathian Basin Wildlife Gallery |

in next time... But I'm waiting for specialist in therivid flies. We must wait just some more time. Perhaps it is possible to get species level.  I have this specimen in ethanol. |

If you have collected the specimen: try my key at http://home.hccne...vidae.html. Be aware that some southern european species are missing! |

Kahis is right, I forgot about some species as strigata / plebeja, which are quite rare here but, possibly, not uncommon elsewhere. Anyway, since it's a male, ID is tricky : bristles on femur 3 are very important and look at the aedeagus. Theo |
