Hi,
This one doesn't look like any I had last year, there is a little hair on the bottom of the eyes.
25th September, feeding on Ivy, my garden south of Lincoln UK.
3 pics, but I have another showing the face slightly more in needed.
Janet :)

Epicampocera succincta perhaps? :)

Well that is a possiblity, as I did have that last year but I didn't think it looked quite the same. It had more hairs on the eyes for one, but I really don't know!
My pics last year were not as good, but I see they both have the hairy fringe behind the eyes. This one only has hairs at the bottom of the eyes, last year's had hairs going well up the eyes, could that be variable?
Aha, I just checked the vertical pic and I can see hairs furhter up the eye!

Great! I like consistency, but new is also interesting! I have more from earlier in the season yet to pin a name on which I think are new to me. ;)

It is Pales, you have been fooled by the first pic.
The tip of the scutellum is red as are the tibiae (pic 2), so it can't be Epicampocera. If you have a very close look at the pics, you'll see the bristles on the face are ascending. Moreover, there is only 1 pair of reclinate orbitals.
(I think I rest my case here)

Arghhh ... I always miss those pale tibiae in photos (maybe they just don't show up as well as on a specimen?) and the facial ridge bristles on this one were a bit confusing ... well spotted Theo :D

Thanks
If you have some intuitive reasons to doubt something, you can start looking for counter-arguments. That helps.

Thank you Theo, I did have Pales pavida last year! It is the only Pales sp. we have as far as I know.
I compared it with the pics from last year, but the angle I took the pics from was different so I wasn't sure.
Here's the other face view cropped..
