Hello,

Thanks,
Michael

Hello Lukas,

thank you for your answer. It seems Stratiomys concinna is not a very frequent species. Du you think the determination is certain enough for the gallery? And how at all do I distinguish the stratiomys species. In the moment I can't see difference between some of the species.

Thanks,
Michael

In my Polish key (Trojan,1963)

1.Antennae black
*S. longicornis
*S. potamida
*S. cenisia
*S. chamaeleon
*S. singularior(=furcata)
*S. equestris

- last antennal segment red or brown-red

*first segment black or brownish - S. concinna
* all segments red ....... - S. ruficornis

Stratiomys on the photo have red antennae and hairs are black on thoracic dorsum (chamaeleon with yellow)

I can send key but in polish.(I haven't time to translate)

Hello Lukas,

thank you for your offer, but I don't need the key. I just wanted to know, which characteristics I have to look for, when I meet a Stratiomys species next time.

I looked other pictures from the same fly, and the last segments of the antenna are in all pictures very clearly redish-black or dark brown. So S. concinna seems rather certain.

Thanks,
Michael
