Winged predator

This winged predator is a common yellow dung-fly I think. I was actually trying to take some photos of a pair of aphids on the rose when I spotted this rather alien-looking creature on the other side of it.

We finally had some sunny spells today but unfortunately they all happened before I went out and I missed all of them! By the time I eventually got to the park this afternoon the sky had clouded over again and I couldn't get most of the shots that I was taking as sharp as I would have liked them. Fortunately I managed to get this one that I was reasonably happy with.

Thank you ever so much for the comments and stars on yesterday's January Rose blip. They're all very much appreciated! :)
