The Pollenia i saw have often golden and somtimes grey hairs. I wonder if this has any diagnostic meaning. (I'll add a few examples) Klaas Klaas attached the following image:  [121.21Kb] |

It is all Pollenia. As you know, there are several species. However, hairs turn less golden with aging, so be careful ! Theo |

I've been looking at Pollenia a bit recently, and I can tell you that your males are not rudis, as yours have contiguous fronto-orbital plates. Rudis males have the orbital plates clearly divided by the frontal vitta, unlike most (but not all) male Pollenia.
