Beetle ID

I came in from the garden last evening and there was a olive green beetle that looked like a knights shield. Not sure if it was friend or foe, gave it the benefit of doubt and put it outside. Looked an interesting fellow, it was properly about 15mm in length might be a tat smaller.

One of the Shield Bugs - well named aren't they? Lots of info & pics here http://www.gardensafari.net/english/shieldbugs.htm
they won't harm your garden.
They are so lovely aren't they? We've got some lovely brilliant green ones and some silvery ones too - what wonderful things nature does huh?
Thanks Dove for that link. I have never seen one before, I will certainly be looking for somemore
These must be some sort of Shield Bug. The triangles on their backs were really golden which hasn't quite come across on my phone photo. Beautiful couple.
Aren't they beautiful?
I think they're Sloe bugs, Dolycoris baccarat, amazing looking creatures. Sorry I hate spell check sometimes, that should be baccarum
They look exotic enough to be baccarat!
