Hi, lost again as usual. Very thin hairs on hind coxa but only two bristles on notopleuron. Arista bare. The very nice colour and those tarsus may ring the bell somewhere. Large fly, 12mm long and only one that size with all those grey Sarcophagini I have. July 7.2008 Loviisa, Finland.

Strange setae on parafacialias for a Sarcophagidae. Looks more like Tachinidae, around Exorista.

Well that is a very good point Stephane. A good reason why my Sarcophagidae key didn't work  I must change the name of this thread. Thank You, I'm blind.  Jari |

Definitely Exorista - possibly rustica group - if it's female then give up ... if it's a male then expose the genitalia and sternite 5 for an ID

Haha, no problem ... it didn't look familiar but then again rustica-group do all look the same  I am sure one day someone will find a way to key females but until then I have to disappoint people sometimes

Yes, that's one of the main reasons why we take specimens and keep reference collections. Our knowledge of what defines a "species" changes with time and if we have specimens we can always go back and re-appraise old records in light of new techniques or opinions
