hi

to give some pics in gallery (Tachina grossa don't have a lot) I would like sure that this is Tachina grossa.
Could anybody confirm please?

Thanks a lot, Brigitte

Certainly looks good to me :)

Hi Chris

Can you see if it's a male or female? Does a pic from the backside helps (if needed)?
Thanks, Brigitte

---

I don't see very many of them but I would say (from the length of the tarsal claws) that it is a male :)

---

Thanks Chris!
does this pic help?
Brigitte

---

This is another one, same day, same place. Is this one male oder female?
Brigitte

---

It just makes it look even more male than before ;)

---

Thanks!

Last pic is another animal. Male too?

---

The second looks male too - long tarsal claws - but I might be wrong :)

---

Thanks a lot Chris :)

---

I've checked mine here and males do have longer tarsal claws than the females so I am probably OK on those determinations :)

---

so I can use "male" for gallery?


all pics which are already shown in gallery are without "male/female" . . .
I'm just searching my pics from 2009, there it must have T.grossa too . . .
no result, very old fly 2009 . . .

Hmm, I think it is fair to call it male ... unless Theo says otherwise :D

---

it is a male.


you can see the large genitalia, though out of focus, and proclinate orbitals are lacking.

Vertex is pretty broad, though.

I'm just the new-comer with a shortage of knowledge, but what I think that picture 2 (the frontal close-up) is from a different lady fly to see to the shape of the eye. Espacially if you compare 1 and 2 together you may see that the eyes of 1 are more oval which is the male, compared to the black like under the antennas and no dark line in the middele of the head.
Could it be possible that you had two flies...?

Regards,
Hedy

I'm afraid you are misled by the different angle of view.
Since the proclinate orbital setae are lacking, the second picture cannot be female.
