Hello, I am sorry, but I cannot agree. This speciment is not Eristalis tenax. Hind legs are not all dark, it has yellow stripes etc.
I have to agree with Anezka. I am sure this is not
E. tenax. Unless it is an extremely aberrant specimen. I simply cannot see even traces of the vertical double bands of pilosity in the eyes. With such good lighting and resolution as is in the picture they should be seen very clearly. Eyes are pilose, yes, but not as in
E. tenax. But anyway, the whole creature is non-E. tenax ;)
No idea either of the species of
Eristalis found in Moscow. A pity the aristae and the pterostigma cannot be seen well. Those would have given excellent clues... But I almost bet that this creature is going to have short and plumose aristae, not long and bare ;)
