At least I think it's a Bombyliidae from the way it flew and the long proboscis (not visible in the photograph). It was BIG, about 17 mm long, photographed near Rome, Italy. Thanks, Sarah |

Hi Sarah It is a beautiful Bombyllidae, however, more of the 'short proboscis' subfamily. I think you are looking by mistake at the left front tarsus ? To me, it seems to be in Anthracinae, but leave that to the experts. Theo Zeegers |

In fact the proboscis doesn't show in the foto, but I remember it as quite long. I'm looking through my discarded shots to see if there's one where you can see it better. If there is, I'll post it later, Sarah |

Just taken a look, unfortunately all the shots are from the back. It was VERY nervous and flighty, typical Bombyliidae behaviour, and it took me an age to creep up on it  , Sarah |

I suspect this is Satyramoeba hetrusca. I think David Gibbs is more familiar with this species, so hopefully he can confirm this.

Thanks Tony, let's hope David can confirm, Sarah |

looks just like my specimens of Satyramoeba hetrusca and as this is the only European species in the genus i think you can be confident of this det. |

David, I did not know this was the only european species in this genus! That leaves no doubts about this other fly you also commented: http://www.dipter...ad_id=2946 Do you have any records about size variability on this species, because I'm pretty sure "mine" was bigger than 17mm Thank you Armando Frazão http://bugs.digit... |

Maybe it's just the angle of the shots, but Armando's fly seems to have a very small head for the size of the body and Sarah's fly does not give this impression. Also, do these matt black Bombyliidae really fade to that sort of bronzey colour? I am just thinking here of my smaller Thraxan, from Australia - I saw lots of these, and never other than the smart black and white. Mind you - the wing venation on Sarah and Armando's flies appears the same, so David must be right.

Actually Armando, 17 mm is a conservative estimate based on memory and it may well have been bigger. In fact, being BIG was the first thing that attracted my notice  ! Sarah |

Well, we may really be looking at the same fly. Yesterday I went for a walk and could take a good look at some Xylocopa violacea, I believe these bombyliids mimic them. Their size is my only real measure of the size of the fly I photographed, and the especimen of X. violacea I've seen average a little below 25mm long. I guess we are getting into a meeting point and I'll be naming mine also S. hetrusca
