Thank you Theo! This species is very common in the dunes. Curiously P. handlirschi also seems to be very common, but more inland. I noticed a behavior in the specimen of the photo that I don't understand very well. I made a video of that (http://www.youtub...bZG15xbHRk). The fly was grasping the sand (at around 45 seconds, for example) and I can’t explain why, can you explain this? |

Out of interest, how are you identifying P. handlirschi?  I notice it isn't in the Central European key  Would be nice if we could update the key if possible. |

As Rui correctly observed, handlirschi is an inland species of hills and mountains. Carbonaria is typical for sandy beaches with little vegetation. IN handlirschi, the antennae is (even) much longer, something like 10 x as long as wide. Theo |

Thanks ... I only ask because I have about 7 Periscepsia specimens from Pakistan and I see from Tschorsnig & Richter that there are 7 spp. but I don't have a copy of Mesnil in Lindner If I could borrow a copy then it would make a very useful scanning project  |

If they are from Pakistan, they can be many things... even Oriental. Theo |

I'm not really identifying them yet. Some months ago Theo explained me that P. carbonaria could be found on the shore and P. handlirschi more inland and that was the reason that I called them what I did. But it would be interesting to compare specimens from different sites. In the Iberian Peninsula only these two species are known. |

Yesterday I saw this fly (seems carbonaria) doing the same as on the Rui's video, but it was on small sand spot in a try meadow in Warsaw PL, far away from any shore

As long as it sandy, it doesn't need to be sea shore Same locality as Germaria ? Theo |

Then it is a very typical habitat. Theo |
