The first is the caterpillar of the Peacock Butterfly. We saw these coming home from school a couple of weeks ago and there were dozens of them. Very bizarrely there were crossing the pavement and determinedly crossing the road. Nothing seemed to stop them - cars, people, grass - nothing. It was a very strange sight. I believe they all leave their 'nest' at once and look for food (which is mainly nettles) but there were nettles on the side of the road where we were so I have no idea what the compulsion to cross it was.
This second caterpillar I found munching away on our raspberry plants. Not something I normally encourage but I left it there in this case! I am not quite sure what this one is but after a bit of research I think it is the caterpillar of the Buff Ermine Moth.
Lastly is this rather striking caterpillar which we found on the Ranges when we went for our picnic recently. It was feeding on Ragwort and it is the caterpillar of the equally striking Cinnabar Moth.
