Dear forum,

I rarely see such kind of syrphids in my garden. So far, I had just individuals, which rather looked like genus Xylota. But could this here now belong to genus Chalcosyrphus, e. g. Chalcosyrphus nemorum?
Thanks in advance for taking a look at this.

Garden, northern upper rhine rift, southwest germany, june, 25th, 2015, size about 10mm

Best regards, Thorsten
