HI,

I only got one pic of this, am I correct that it is Eupeodes lapponicus male? I think it was on a Lupin flower, my garden, Lincoln UK on 24th June. Thanks for any help!

Hello Andre

I wonder if you would kindly tell me what the identifying criteria is for Eupeodes lapponicus which separates it from Eupeodes luniger.

(I can now take better pics with my macro lens )

I do not agree with Andre. In E. lapponicus, the side margin of tergite 5 is at least partly black, while in this specimen it is entirely yellow. E. luniger is much more likely, based on the yellow side margins of tergite 5, the yellow hairs on the scutellum and the yellow abdominal spots not reaching the side margins of the tergites. Besides, the genitalia are not conspicuously large, so that rules out E. corollae.
The best character for E. lapponicus is the sinuate vein R4+5, but this is not visibe in this picture either.

Thank you Menno.

I'm sure Andre had an off day, and I take some of the responsibilty as I did place the suggestion myself as at the time it looked to me like E. lapponicus. I'm not an expert and don't have keys, but I try to learn from what I find out here.

I found E. lapponicus is a rare fly in the UK so had to be certain. Thanks to all here for your help.

I agree with Menno... I am puzzled, is this the picture I based my opinion on?
My humble apologies, because for me this is a clear E. luniger too...
I am very very sorry! Hope I can make it up to you some time!

Please don't worry about it Andre, we all make mistakes at some time.

You more than make up for a small error for what you do here!
