I found at home these bright yellow haired Eristalis flies at least two times. I know this species has a large amount of variation, but I have not seen this colour even on the net yet. I have also compared that specimens with Myathropa florea, but the wing venation, apart from size, is different. The collected one was identified following the keys as E. tenax, although I can't see the hairs on halter-barette (do you have any picture of that feature? I would say maybe pubescent, but not hairy). The arista is bare and the eyes haired but I can't see the two bands. (IBERIAN PENINSULA: CATALONIA: Girona province, Beuda, 400 masl, the living specimen April the 24th, 2013, and the collected one April 2015 (day unknown)). Could anybody confirm is or not Eristalis tenax? Edited by rafael_carbonell on 23-03-2016 14:29 |

Rafael, it is a female Myathropa florea. No possible doubt whatever. I don't know what you see in venation that doesn't fit, it will be due only to normal variation. What should be there is there  Size can also be extremely variable.Best Piluca |

Hi Piluca! You are right, my brain did a wrong shortcut.  In fact, the "cell R1 closed before/at wing margin" is a good character. Better than the one postalar pile tuft present/absent used at StN keys Below is a picture of a M. flora, this specimen and an E. tenax. |

The three specimens. I would say M. florea is also quite variable. Thanks, Piluca, see you soon.

The right specimen on the last picture is Eristalis (tenax ?).

Yep, sorry, from left to right: M. florea (the form I was used, autumn), M. florea (the spring form I was not used) and typical E. tenax |
