Hello, which tachinidae - if at all - is this? Thanks, Michael (photo taken today, rhineland/germany, size about 8mm) Michael Becker attached the following image:  [71.35Kb] |

Caliphoridae - Pollenia sp. - from the curly, golden hairs on the thorax

Hi! I vote against Tachinidae, I think it is a Pollenia sp. Calliphoridae rather, but I am not an expert.... |

Oh no, an undeterminable Pollenia species again.... Besides, how do I distinguish Tachinidae from Calliphoridae? Or isn't there a simple way? Michael |

In this case, the golden hairs on the thorax, very distinctive |

It's not easy to see any of the features that make a tachinid while in the field - or even from a photo for that matter - because they're relatively hidden (subscutellum & hypopleural bristles). But I'd say this fly is hairy, rather than bristly so it's unlikely to be a tachinid. A bristle is a strong, socketed hair - look at one under a microscope and you'll see that a bristle mounts into a 'ball & socket' joint on the body. But really, there's no substitute for experience - just learn what the various groups look like |

Thanks for your answers. I will try to differentiate between hairs and bristles next time. Probably I still will be often wrong and need help. Michael |

This Pollenia seems peculiar in having the topcel closed. That might even help to get to species level, but we need an expert. Theo |
