Hello,

three years ago I found my first Ectophasia here (meanwhile they are rather abundant), but I was in vain waiting for my first Cylindromyia - until this August! Unfortunately I could only take two bad photos from 5-6 m distance, before it flew away :|.
Is anything more possible than just Cylindromyia sp. (maybe from distribution, date, size)? On Heracleum sphondylium near a small creek, about 10 mm (roughly estimated from the distance).
I went to the location again in the last days hoping to find one again to get some better pictures, but the slope has been mowed. No Heracleum flowers any more...
