1. Sphaerophoria sp - female
2. Parhelophilus sp.
3. ??? Melangyna.

Sorry I cannot be more precise - a suite of shots that lie amongst difficult groups.

Regards

Roger

Well Igotthe families OK. I thought interuppta on 1. on 2 I thought maybe frutetorum as you can just about see the rear female is swollen with hairs.

N0 3 still no clue although I did think about Ripponensia but the legs were wrong colour. Looked at M Cincta but did't know the wings could foldover the body.

1. was in my Garden Redditch , Worcestershire. 5219'4" N 155'6" W

2/ Abbey Meadows Redditch 5218'57" N 155'19" W

3, Abbey Meadows, Redditch. 5219'3" N 155'27" W

2 and 3 are beside water

Thanks for trying

Sorry - I should have given feedback on the reasons for IDs

I thought interuppta on 1.

FemaleSphaerophoria cannot be done with any confidence and although I have tried using the Finnish key I have found it very tricky even with a microscope and ability to rotate specimens to see features. I am advised by others that parts of this key don't work, so it is best not to even attempt females. Males are doable, but only on internal structures within the genital capsule.

2 I thought maybe frutetorum as you can just about see the rear female is swollen with hairs.

Separation of Parhelophilus is tricky - both males and females have eyes separated. In males the separation is on the presence of a distinct tubercle on the underside of the hind femur in frutetorum - cannot be seen from above. In the females, the separation is on the presence/absence of black bristles on the occiput (back of the eye. These bristles are jolly tricky to see even under the microscope.

N0 3 still no clue although I did think about Ripponensia but the legs were wrong colour. Looked at M Cincta but did't know the wings could fold over.

This one gives me all sorts of problems - certainly around Melangyna/Meliscaeva but there is too little to go on and be certain.

Can you let me know when these were seen please?

Regards

Roger

When you look at the first pictures, you get the impression that it has been treated, but it is not. That's sublime.
