Picture taken in the "Fagne of Malchamps" in Belgium in april. It is a wet area. There were 3 of these Tachina. Is it Tachina ursina? Thank you Edited by Christine Devillers on 11-02-2009 16:04 |

Hello, Christine! Christine Devillers wrote: Is it Tachina ursina? I'm no expert, but I dare to call it Tachina lurida (typical spring species). Best regards, Jürgen -=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-= Juergen Peters Borgholzhausen, Germany WWW: http://insektenfo... -=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-= |

Looks like Tachina ursina to me - white band on the anterior margin of tergite 5  |

Both are right, it looks quite like lurida, but actually it's an rather unusually reddish ursina for the reaons mentioned by Chris. Theo |

Thanks I thought at ursina for the same reason than Chris, but I didn't know if it was enough. In the keys: cheeks with black hairs, length of 3rd antennal segment... It isn't necessary to look at all these details? |

You can look at other features, but it is not necessary. Identifying flies from pictures requires features that are easily seen in pictures. The relative length of the 3 antennal segment can vary significantly with the angle of view and is therefore quite tricky. The band of greyish dust is, in this case, always clearly visible and therefore very reliable. Great pictures, by the way. Theo |
