Gorse Weevil Exapion ulicis
I found this on a gorse flower. This was certainly before I had Duff, but I think I might have started to use Hackston's keys back then. However I can't honestly say for certain whether it was keyed out or just identified on the basis that it was on gorse and looked like a Gorse Weevil...

By the time I found this one I would have at least been using Hackston's keys if I didn't also have Duff.
