Many thanks Jorge : I updated the title... I thought Tachinidae had long hair on their abdomen... Pierre OGER 4217 H?ron (BELGIUM) |

Pierre - the phasiines (Gymnosoma, Phasia, Ectophasia, Cylindromyia etc etc - there are lots of genera) are very atypical tachinids - often having bright colours and just a slightly hairy body. Novices often confuse them with syrphids because they behave similarly and sit on flowers a lot. They are still tachinids though because they are all parasitoids; they are calyptrate flies; and they (99%!) have a strong subscutellum. |

Okay, thanks to this new tip :-) But, and that's strange, I don't have many problems with syrphids : I can recognize them (the family, sometimes the genius) and I don't confuse them with other families... Again my thanks, Chris :-) Pierre OGER 4217 H?ron (BELGIUM) |

@Theo : Don't know it and don't find it on Fauna Europaea nor in my book about Syrphidae... Only 1 occurence in Google and the site is not reachable... Is it another name for it ? Pierre OGER 4217 H?ron (BELGIUM) |

Thanks Gerard I read that it is in UK endangered... and not known in Belgium : so I don't think I will encounter it. But that's true, it seems difficult to believe that it is a syrphid

Hello! Chris Raper wrote: the phasiines (Gymnosoma, Phasia, Ectophasia, Cylindromyia etc etc - there are lots of genera) are very atypical tachinids - often having bright colours and just a slightly hairy body. And in this genus also the name reflects this : Gymnosoma means "naked body" (or abdomen).
