Teeny Weeny Caterpillar

We watched Trooping the Colour this morning followed by the fly past at Buckingham Palace.  

This afternoon I have done some gardening, albeit very gently.  I've also stretched out my back and not done too much sitting down, although I am still ploughing happily through The Mirror and the Light.

I have no idea what this centimetre long caterpillar is, but it is wandering around the rose leaves, no doubt causing trouble.
