Hello! This picture of a fly I took yesterday here in Ostwestfalen/Germany. Can someone tell me what genus it is? Thank you!

Hello Juergen, In my opinion this one should be looked for in the family Tachinidae! There are other people in this forum who can tell you more about it I think!  Greetings, Greetings, Gerard Pennards |

Hello, Gerard! Gerard Pennards wrote: In my opinion this one should be looked for in the family Tachinidae! There are other people in this forum who can tell you more about it I think! Thank you! I already thought of a tachinid, too, but the wing vein pattern (I hope that is the correct term in English) also reminded me of some Calliphoridae.

Hello Juergen, Yes, it is sometimes very difficult to see from a picture what family it is, if the specimen would be available it is (a bit ) easier.In this case the fly is more bristly than most Sarcophagidae are, although I must admit I am not an expert on these families! So we will see what happens when one of the experts on these families looks at it!  Greetings Greetings, Gerard Pennards |

This is a Tachinid indeed. In general, it is very difficult to explain why. Most Tachinids are more bristly than Calliphoridae, as Gerard correctly explained. But then again, most Phasiinae (subfamily in Tachinidae) are less bristly and often taken for Syrphidae - lookalikes ! Most males in Calliphoridae have the eyes very close together, leaving only a very narrow vertex. Most Tachinidae have, in the male sex, a broader vertex. This one clearly has a narrow vertex and therefore ... it is a Tachinid. (Yes, I know, ...., but don't complain at me !) The species is quite like Ernestia rudis, a large and quite common species. Its larva parasite Panolis flammea, and therefore it is confined to coniferous and mixed forests. The males are often found occupying a territory from a leave of, say, Fagus. Theo Zeegers |

Hello! Thank you very much for your explanations! Zeegers wrote: The species is quite like Ernestia rudis, a large and quite common species.
