Thread subject: Diptera.info :: Miltogramma germari?

Hi,
Recently I spotted a member of Miltogramminae on Achillea. It was a Miltogramma, and I think it could be M. germari, though there are more species around Berlin. To exclude M. oestraceum one should check the fore tarsus of the male - but how can I recognize the sex here? The tarsi are unmodified, but that is normal for females of both species...
Help is appreciated! Regards, Sundew

Sexes are indeed very similar, so you need to check for the genitalia.
We cannot see those, but the abdominal tip looks malish.
Germari definitely occurs around Berlin, whether oestraceum does I am not sure.

Thanks! For our region the species germari, murina, oestraceum (oestracea according to Fauna Europaea), punctata, rutilans, and testaceifrons are listed.

OK.
-gramma is neutral, so all endings should be -um (where relevant: of course rutilans is OK).
This is either germari or oestraceum, you can forget about the others in this case.
