This fellow crept onto my hand as I was sitting on a picnic bench at The Lookout in Swinley Forest, Bracknell. The area is heavily wooded, lots of pine trees but deciduous as well.
No interactions present.
It's definitely an aphid. It's probably a young Cinara.

In Swinley Forest - large managed woodland between Bracknell and Ascot - next to visitor centre. Forest densely populated with conifers but there are plenty of deciduous trees around too.
