See similarly dark-marked observation of a confirmed male E.lundbecki here :
https://www.inatu...s/19667946
That one was confirmed by Erling Olafsson at National Institute, who stated at the time :
"This seems to be a very normal Icelandic E.lundbecki. I have no specimens with "full“ abdominal markings (European style), some even with plain black abdomen (no visible markings). Reduced markings are common among other of our syrphid species aswell, for instance Syrphus. In some others they are variable, for instance E.borealis. Perhaps dark coloured individuals have priority in our cold climate with limited sunlight. ."
Also on that observation, there is a comment from Bill Dean saying :
"Very difficult from pictures but can anyone give an alternative identification. However, the upper outer cross-vein in this image is more re-entrant than in the Steven Falk images, making the area from upper outer cross-vein to wing edge wider than in Steven Falk images, so, I wonder if lundbecki comprises more than one species as you wouldn`t expect such variation in the wing..."
Maybe this is something completely different though! ??
