Dear community
because I want to use this photo for an article I would like to ask your opinion about this species (i'm not a dipterologist): Eristalis tenax? Photo taken on 11 Apr 2014, Zürich CH.
Many thanks, Beat
I am no expert.
I can only say that I think this could be Eristalis nemorum.
There is a small dot in the wings...
But wait for the experts.
Sorry Juergen.
This means I agree with you, for now I see that nemorum and interruptus are synonyms.
