Hello,
this fotos of a Tachinidae fly are done on 01.08.2019 in South Palatina, Germany, ca. 200m NN, on a single hill with much orchids in the Rhine river plains.

I’ve shown it in the german forum insektenfotos.de, but without a satisfactorily result.

My first idea was Tachina fera, but anyhow it don’t looks like a Tachina. Then I think about Peleteria rubescens, especially seeing the white shadows on the Abdomen and Nowickia ferox, but both they should have black legs.

This fly has brown legs, and so I think it cannot be one oft them and I am back on Tachina fera too.

Is it so or is there any other idea?

Thanks for your answers, Rainer

this a foto from the back side with the white shadows at the abdomen

and this is the last

I am not an expert, but this fly seems to lack "Peletrria hairs" on the face, so this genus is out of the race, I think.

Greetings,

It is Tachina fera/magnicornis.

---

Thanks for your help, after all a Tachina.

I've attached a clipping from the face - is it possible to separate T. fera from T. magnicornis?

Best wishes, Rainer

It is intermediate. It is a male with proclinate orbital bristles, hence suggesting magnicornis. However, the metatarsi are clearly red, hence suggesting fera.
Moreover, the third antennal segment looks feminine rather than male.

So, it is either an intersex or and aberrant specimen.

Thank you Theo for your explanation. These potentials makes it not more easier for beginners like me. - Best wishes Rainer
