Nice Siphona ... would be good to see the head from the side, showing the ratio of antenna to frons  Though I am sure you know it's nigh impossible to identify them from photos  |

Thanks Chris, I'll check what I have (or we should address Nikita who got the specimen). |

Hi Black Marvelous pictures, still, Siphona are very difficult. This one might be S. mesnili (the epaulette are quite dark, the thorax is vittate, DC 3+3, laterals on syntergite 1&2 present) Theo Zeegers |

Thanks Theo - I still have to check available images (delay caused by my PC crash, now fixed). |

Hi Black, Yes, this helps. It is Siphona ingerae, readily IDed by the relatively (for a Siphona) long pulvilli. Could have seen that before, the head shot with the broad jowls put me on the right track. Marvelous pics, Theo |

Many thanks Theo. This applies to the first fly, right? Could you please tell are these two of the same sp.? |

Black, I always looked at your photos with admiration. You should publish the first(?) diptera coffee table book  |

Thanks crex - I would still reserve the right to produce something even more ponderable one day ... |

I'm not sure whether it's the same species... May 03, 2007, sitting on a big conctete pipe covered with lichens, edge of pine forest. Size 5 mm. |

Certainly a Siphona sp., but you knew that already. I just see the common species here, like S.geniculata (which coincidentally has been out in good numbers very early in England) and species like S.ingerae are but a dream! |

Thanks Chris - do you know anything about host records of S. ingerae? |

Most Siphona hosts are found in Lepidoptera, only geniculata and some others changed to Tipulidae. Theo |
