Looks a bit like a treehopper headwise but v.short spotted wings and nothing like anything I've seen in Chinery British insect ID book.
No interactions present.
Lots of useful images therein - and vastly superior to Chinery (which illustrates badly just a handful of the 35,000 invertebrates known in the UK). Good luck.
