Hi, this one I found on the same day 22nd May in the same area as the previous one but an hour later, so probably another fly..

Hello bonitin:)

In your second pic I think I can see some black hairs on the occiput, if so then it would be Parhelophilus frutetorum I believe.;)

Is it possible to crop that part of your pic off to bring it closer?

Janet:)

Hi Janet, thanks! :)

Problem is that these pictures were already very cropped, I had to take the pictures from a big distance, some tall Brambles didn't allow me to come closer :|
But I cropped as much as I could, hope that will be sufficient.

I do see black hairs in between the eyes on top of the head, but not behind the eyes...?

Hmmm, it's a little too difficult to see properly.;)

I think I can see black hairs going down the middle of the back of the head in your first crop, not sure if that counts though!
:|
Neither of the crops look to be the same pic as the second one, was that one fully cropped?:)

oooh you're right, must have cropped the wrong picture..
I'll see if I can find the second one back..
What confuses me is that they say a row of black hairs but I don't know if that row is supposed to be vertical or horizontal..

Could I call this one Parhelophilus versicolor cf. ?
Or is the lack of a row of black hairs on the occiput not enough conclusive ? :)

I personally think Parhelophilus cf. frutetorum, due to the quite widely spaced pale spot at the bottom margin of tergite 3 from the two lateral spots....and I think you would find black hairs on the occiput with a clearer view, but don't take my word for it as I am not so experienced as others.;)
