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

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

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

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.

Thank you. Yes - I've done it now. The file was too large.

no blanks in filename, file size reduced (below 300 k or so).Did you fulfill these criteria ?

I've repeatedly tried to upload a photo with my thread but nothing is showing. I can't see that I've done anything wrong. Can someone please assist?

I might add that this is a great resource and I am really thankful for all the members help.

Thanks for the explanation Paul. It definitely stopped me from flooding the forum with my threads Wink

Each user has a maximum of ten new threads per day (24 hours). Just to prevent a single user from sending scores of his unidentified fly photos at once and thus drain out any other threads.

Hello, I'm having a problem posting new threads, as the "No new Threads allowed..." is showing up on all of the forums. Is there some sort of thread limit I've exceeded?

SabineH: you have to be logged in to see "New Thread" in the right upper corner of each "forum" site. In the case of accidental logout you have to start over.
