This is an Italian Striped-Bug (Graphosoma lineatum) aka Minstrel Bug, about 1cm (0,4") long, but not all that hard to spot:
Olympus XZ-1, 28mm, ISO400, f5.6, 1/80s
Their having sex seems to be a bit awkward, but then again, I know little of their customs:
Olympus XZ-1, 112mm, ISO100, f8, 1/250s
Thanks for watching!
