This fly (12 mm) from my garden, Kapellen, Belgium, looks like Sarcophagidae to me. Is genus (Sarcophaga?) or even species possible? I kept the specimen, so pictures can be arranged (I have to buy a ring flash asap because the shadows in the picture are horrible). Thanks in advance!

Looks like Sarcophaga carnaria/variegata group to me ... you'd need to extend the male genitalia and hook the parts out to get to species :)

---

I'm afraid I don't have the equipment to prepare genitalia properly. Anyway, thanks for replying.

---

Well, all you need to do is to use some pins to lever out the larger parts, while the fly is still soft (but they do lock inside when dry and can be very hard to extract). The cerci clip inside, like on a Swiss Army Knife and it's the shape of those that determines the species :)

---

OK thanks, I'll try. But is this a male?

---

Yes, it has the characteristic rounded genital capsule on the end of the abdomen. The bits you need to see are folded under and slightly inside the abdomen. You need the fly to be completely relaxed and soft and then the abdomen can be stretched lengthways a little and some pins can be inserted to lever out the cerci :)

Unfortunately, this specimen was totally dry and stiff, so I ruined it completely while trying. Next time I will try again. Thanks for your explanation.
