Hello

I found this hoverfly around a small forest pond. I think it's either a Xylota (abiens or close) or Chalcosyrphus nemorum. Is it possible to know the species with this single picture ? This hovefly was quickly distrurbed by a male Helophilus and I didn't see it again.

Bois de la Couronne, Clicly-sous-Bois, Seine-Saint-Denis, Île-de-France, France

Chalcosyrphus , should be C. nemorum, male.
