Hi,

I am working with my Sarcophagidae and am a bit lost with this one. Yes, it's dirty because it's from malaise and I may wash it clean if it turns to be something interesting. It really don't fit any keys, so can it be maybe a Calliphoridae ? Arista is long plumose, long bristles on R1 and R2+3 and there is no Tachinidae-like sub-scutellum. Maybe it's just something I really should know, but now I'm lost. Any ideas ? July 9. 2010 Loviisa, Finland.

Some kind of Tachinidae, I'd say.

Thanks. Maybe I must change the name for this thread.

If there really is not sign of a subscutellum then it can't be a tachinid ... sure there are tachinids without (eg. Litophasia) but they don't look like this. Could it have a partial subscutellum, like a rhinophorid? The head is quite round and the calyptrae seem small and do not hug the scutellum.

Definitely a Sarc.

Difficult to see, first impression is Sarcophila latifrons, but the frons seems too narrow (?)
Start checking the hind coxa for setulae

I agree on Sarcophagidae.
But it is not Sarcophila which has a different abdominal pattern.
It is a female Sarcophaga s.l.

BTW A lot of the smaller Sarcophaga's have Rhinophorid like calyptra.

Theo is right "Definitely a Sarc". I also agree with Liekele that this is probably a female of Sarcophaga s.l., and if so it is likely subgenus Heteronychia (faint fumosity of wings could be a hint that this is S. depressifrons). However, I cannot entirelly rule out Blaesoxipha lapidosa without having a better view of the head profile and the larvipositor.

So Sarcophagidae after all. It does not have that blade like larvipositor, so Sarcophaga female. Following the key it has 3 strong dc and the first one is closer to suture than to second; terminalia is blackish brown; vein R1 is setose; postgenal hairs are white and vein R1 has 7 setae. Conclusion: Sarcophaga (Heteronychia) depressifrons with slightly fumose wings :)

Thank You once again

Hi Liekele, Thomas,


that was my second thought. Sometimes better than the first. Anyway, I already gave the argument why it couldn't be Sarcophila.
