Hallo, I just used one of the rare opportunities to take a photo of a living insect in that insect-poor times. I suspect it is 'Eristalis , that's why I post it here. If it is another family, would you please transfer it? I was very surprised to see the mating couple change position several times, without leaving the leaf, they were sitting on. I watched the couple about one minute. It was already in copulation when I came nearer. I attach a photo from every position. I would like to know, if this behaviour of changing position is normal in that species or in that genus. And of course I hope, you can identificate the species. Germany, Baden-Württemberg, Dreifaltigkeitsberg near Spaichingen 48,083332° 8,76299° 990 m at 9th May 2018 on leaf of Tilia |

Hello, Siga wrote: I suspect it is 'Eristalis no, wing venation and shape of antennae do not match. I think it is Criorhina (asilica?). Best regards, Jürgen -=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-= Juergen Peters Borgholzhausen, Germany WWW: http://insektenfo... -=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-= |

@ Siga, Its still in the correct place in the forum, Criorhina is a Syrphid fly, too. |

Thanks for your remark: the much better. I hope someone can tell the species (confirm Jürgens suggestion) and/or make some remarks to the switching from one position to the other during coupling. |
