Yes no doubt for Eristalis. Probably Eristalis tenax, given the thick tibia 3 and vertical stripes of hairs on the eyes, although difficult to assess on a single photograph, as it may also result from a narrow focus range. do you have other photographs of the eyes ? Cheers Gabriel |

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 am not sure, which species are in Moscow, but if it was from middle Eurepe, I would say it is male Eristalis interruptus. Greetings |

Hello That colour of legs is typical of E. tenax: "pattes noirâtres avec base des tibias et genoux jaunâtres" Rafael |

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 |

Eristalis nemorum (=interrupta) Pterostigma and arista is indeed not visible, but the combination of: dark venation, specific shape of shiny yellow markings on teg2, golden thorax and yellow face is characteristic for that species. |
