Many thanks, Menno - it's good to hear that you also tend to S. selenitica. However, the sternite markings are dubious. May be they are not square enough, but nevertheless they are broader than high. In S. selenitica it should be quite the opposite. I add a normal S. selenitica viewed from below for comparison. At least the dark center of the markings is higher than broad here.
Ok, the upper fly is generally untypical. Is there a taxon name like "var. unicolor" for a melanistic appearance?
