Large Cabbage White Caterpillar

I did manage to visit my brother this afternoon and photograph some bees, butterflies and this caterpillar in his garden. I don't like caterpillars but I liked the colours of this one against the pretty pink stock. Apparently if they cant find brassicas the next best thing they like is stocks.
I'm still catching up with comments after my bad eye day yesterday, so bear with me I will get to you soon!
