Hello,
I was astonished to see this 
Eristalis at a puddle deep in a dark pine forest yesterday (
together with a Helophilus pendulus), northwest Germany. 95% of the now flying 
Eristalis are 
E. pertinax, the rest 
interrupta and 
arbustorum (no 
tenax at the moment). But this one was neither 
pertinax, nor one of the smaller species I think. I was only slightly smaller than a 
tenax female.
Unfortunately I could only take pictures from some distance. Is it nevertheless possible to tell the species of the 
Eristalis?
