Hello, On October 6, 2018 in the south of France on ivy. I don't know if a photo of the genitalia of a male Sphaerophoria is enough to determine the species? Thank you for your help Liliane D attached the following image:  [194.7Kb] Edited by Liliane D on 28-10-2018 09:16 |

Sphaerophoria is very difficult... In the book "Britain's Hoverflies" by Ball & Morris 2015 the male genitalia of three frequent species are pictured (see screenshot), but I cannot decide which one is the most matching. In the males of the most frequent species S. scripta the abdomen is longer than the wings and, in a resting fly, protrudes beyond the wing tips. If this character is not cleary seen, I do not dare a guess. Regards, Sundew Sundew attached the following image:  [29.69Kb] |

Hello, doesn't the rule apply any more, that if the wings overtop the abdomen in a male, it is S. scripta? This is clearly the case here. Best regards, Jürgen -=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-= Juergen Peters Borgholzhausen, Germany WWW: http://insektenfo... -=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-= |

Thank you very much, As I had a good photo in vivo, I wanted to know if it was enough, but I now know that it is not precise enough. I really like that there's another identification rule. Here and in my other pictures, the abdomen is much longer than the wings. If the rule is sufficient, it can be called Sphaerophoria scripta. |
