the funkypancake insect identification service #2

keith sent me this picture and said:
“The attached shot is of a bug I found on some sweet peas growing in our garden in Southampton. Judging by this site:
it might be some sort of Hemiptera, but that doesn’t mean anything to me so if you run out of things to post, feel free to put it up for readers to come up with a more meaningful name.
Apologies for the large file but I wanted you to be able to enjoy the full horror of it; if you zoom right in, he appears to have actually turned his head towards me to get a better look, if those are in fact eyes on his head….. ”
so, what do you think ?
