Hallo,
diese große Fliege - bestimmt 1,5 cm - saß heute, am 13.8.22 auf einem Blatt der Johannisbeere. Bei der Zeichnung des schmalen schwarzen Streifens bin ich mir nicht sicher, ob es nicht eine ganz andere Fliege sein kann?
Grüße
Chris

I see ocellar bristles. Do you agree? (please view the attached photo of a genitalia confirmed Peleteri rubescens)
- at most hind tarsi reddish brown (yellow when in alcohol) = tachina
notice that the hind tarsi are infact reddish brown.
- legs all black, sometimes tibia lightened = Nowickia
I key to Tachina based upon the aforementioned key features.
I suspect Tachina magnicornis but i am not a Tachinidae expert.
I do not agree with Peleteria simply because of the ocellar bristles.
I must admit, that I cannot see, if there are ocellar bristles or not on any of the photos... I see many bristles, but I do not recognize exactly, where they rise from, nor do I see, where the ocelli are located.
I know that you have trouble seeing but there is no need to defend yourself. Tachinidae are very difficult and it is easy to overlook features. I have seen Theo misidentify many times due to overlooking features. It is normal to battle Tachinids for an id. Very stressful. John Carr at diptera.info is very good at placing Tachinids into a family, subfamily or genus. You could try the diptera forum. Just be sure to point out the ocellar bristles, oe, tibiae and tarsi so these features are not overlooked.
My id for this species is Tachina. I saw the post and i wanted to help you get to the correct genus. I disagreed with Nowickia and Peleteria. I keyed the species to the genus Tachina. From there, my thoughts are morphologically based and this is not scientific. I noticed that the black vitta on Tergite five T5 is not exactly pointed. I'll attach a photo of a typical pointed vitta on T5 of Tachina fera. The parafacialia seem to be whitish instead of golden. I just thought that perhaps it is magnicornis (even though the last article of the antennae do not seem to be large, or magna+cornis).
It is a freak specimen, indeed! thus, someone suggesting "I Think" is a normal answer in this case. I have no objections to someone naming it fera. I have not examined a magnicornis specimen before, so i am not qualified to object. Just be aware that it is not normal morphology for either species (T. fera or T. magnicornis). edit: so these are actually very cool photos!
