Dear forum,

in this thread:

I understand that e. g. the bristles on upper head are helpful to separate S, opaca from other species.
As these ocellar bristles are a bit visible on my pics, I dare to show that fly here.
Thorax did not appear shiny, neither "live" nor on pics, so maybe S. sexmaculata ist not likely?
What do you think? Thanks a lot in advance for taking a look at this.
