Hello Forum,
who can help with this very bumble bee like syrphid? Hagen, NRW, Germany, alder marshland, 175msm, on the bark of a Fraxinus excelsior tree, March 30th 2010,
Another guess: Criorhina ranunculi?
Best regards,
Josef

Hello evrey one,
I also think
Criorhina ranunculi female, the tip of the abdomen may be white or orange and larvae are macrophages, microorganisms filter feeders, like other genres Myolepta-Ferdinandea-Callicera-Ceriana-Xylota-Sphiximorpha.
beautiful photo !
