Is this fly a Phyto melanocephala? Photographed in the Netherlands 24-5-09. Bergen (N.H.) A similar fly was determined as Phyto melanocephala on waarneming.nl. But there are differences with the fly on http://www.dipter...d_id=21675 How is that possible?

Sure. Slightly sexual dimorph. Moreover, the point of view is totally different, resulting in different visibility of the dusting. Dusting is best seen obliquely from behind. These differences can be extremely tricky, when comparing 2 photo's. With a series, such an error can be prevented. SO.... to me Phyto melanocephala female. Which is a great find in Bergen NH. Theo |
