Hello! This one from yesterday afternoon at the beech forest (northwest Germany) was at least at large as a Tachina fera. The photos in the gallery lead me to Blepharipa pratensis? Correct?

A late Ernestia puparum perhaps? Hairy eyes & projecting mouth-edge would suggest it isn't Blepharipa  |

Hello, Chris! Chris Raper wrote: A late Ernestia puparum perhaps? Hairy eyes & projecting mouth-edge would suggest it isn't Blepharipa Thank you! When seeing the fly, I thought of Ernestia rudis or the like first. But when looking through the gallery, B. pratensis seemed to fit better...

It's hard for me to say exactly - but Ernestia would be my best guess ... whether it is puparum or rudis is difficult to say but Theo might be able to use his experience to pick out details that I can't see |

First impressions are often very accurate: A male rudis it is. Puparum has an abdomen like a pedestrians crossing 'zebra'. Moreover, puparum is restricted to april, rudis is second half of may - june. Theo |

At least I got the genus right  I have never seen either rudis or puparum in the wild here  How rare are these flies in northern Europe Theo?Maybe we could have these photos for the Gallery too?

rudis is quite common here, no problem. Males are territorial on leaves of Fagus, but only at borders of Pine forests. That makes sense, since its host Panolis flammea is restricted to pine. Theo |

That explains why I don't see them here then - got to go a long way to find much pine around me |

Hello, Theo! Zeegers wrote: First impressions are often very accurate: A male rudis it is. Many thanks! It it not the first time I wondered, why Ernestia rudis is rather common here, because we don't have many pines - but some can always be found between the 80% beeches, 10% oaks, larches and some other trees. Especially at the location, where I found this fly, there was a small pine plantation (only about 50x50 m) near.
