Hi, I'm still very much strugling to get to grips with all those families. It's much harder than I thought. So once again I have to turn to you for help. What is it and how can I tell? Thanks, Andr Andre Jas attached the following image:  [40.61Kb] Edited by Andre Jas on 27-10-2006 23:01 |

Maybe Tachinidae Siphona? Robert |

Yeah - I'd go with Siphona sp. (based on the long, hinged proboscis - and i think i can see a subscutellum in one photo, which means it is certainly a tachinid) and possibly S. geniculata (based on the presence of median-marginals on T1+2 & the general grey-brown colour) but that a very rough identification  |

Michael?  Median - means along the middle or mid-line of the body Marginals - the bristles on the margin, or edge of a tergite (the chitinous segment on the dorsal (top) side of the abdomen) So, in your third photo you can see there are 2 bristles in the middle of the margin of the first abdomenal segment (T1+2).  |

Hi Chris (aka Michael, sorry for the cockup), Now I get it! And I looked at the original image, and yes there is a subscutellum visible. Thanks a lot. Andr Edited by Andre Jas on 03-10-2006 10:26 |

Andr? The terms median and marginal aren't in the Glossary yet (Submit Chris?) but many other useful terms are: eg. tergite, T1, T2 etc. Calyptrate id relies on chaetotaxy- >Glossary>Chaetotaxy>and then follow the link to the CSIRO site . Study the Calyptrate and then try the Wikipedia pages for family descriptions. These are the most difficult fly families and were left out of many early monographs (those prior to the invention of the "chaetotaxy formula" for terminology). Anthomyiidae (which used to be Anthomyyinae of Muscidae) and Muscidae in the modern sense can be hard to separate without specimens.Tachinids, busy, often biger flies with plenty of bristles or distinctive shapes have more "jizz" (also a glossary word)Best of luck Robert |

Could also be Siphona cristata. For the new readers: IDing Siphona from pictures in impossible. So my guess is as good as yours Theo Zeegers |

I'm tempted to correct Theo: IDing Siphona [deleted] is impossible.

'is impossible' is what I meant of course. I disagree in most cases with Kahis, but i can understand all emotions from frustation to anger in the case of Siphona. Kiitos Theo |
