Hi

This looks likely to be S. rueppellii but females are tricky. I'd be happy to take a look at the specimen. It does not appear to be known from this site as far as I can see from the database and the site as a whole has scope for a great deal more recording.

Regards

Roger Morris

Thanks for that Roger. I have a second view of the lateral surface which was also supposed to be on the same word document attached to the original query, but which sometimes, and perhaps in your case, failed to appear when viewed. This second one is attached this time. I hope it clarifies, because I'm sorry to say the specimen has succumbed to a busy office and now can't be found ........

Whisby Nature Park has not been covered anything like properly for hoverflies and if that could be rectified I would be very happy to assist. There are good facilities here for visitors. I'm afraid whatever ID skills I once had have been severely eroded, but I would like to pick up the pieces again as far as time allows.

Hi Phil, could you take a look at my post of Tues 7th Nov. Is the fly I picc'd the same as yours?
I have been looking via Google for indentfying pics but can't get any. I managed to get 2 pics of it but when I tried to get closer it was gone.
At the time I thought it was Balteatus - of which there were quite a few about. It was only when I looked at the image on screen I realised it was something else.
I have enlarged the pic and attached it. Looking again it does not seem to be the same.

Hello Ben - before I start, I want to emphasise my modesty and falliability in my opinion here, but I would say that it is definitely a Sphaerophora sp. and would tentatively suggest that it does look a good deal like my insect, but I'm sure someone more knowledgable will chip in.

Thanks Phil, I have got it spotted I reckon - it is Sphaerophoria interrupta

I thought it was the Sphaerophoria family and went through the various members that were mentioned in the Levy's 1998 book on Somerset Hoverflies.

Interrupta fits it to a T. The pic is almost identical. see my post.

Gentlemen

It is NOT possible to identify Sphaerophoria from photgraphs - you need to look at the genital capsule.

So - you CANNOT give an ID to these photos

Sorry, but there are limits to picture identification
