Thanks for confirming for me. First time I've noticed them - I actually thought it was a dying leaf on the shrub at first. Poor chap - they were not there today so I hope Mr Swallowtail is off enjoying himself after an afternoon's nap

Having looked up what they look like at the caterpillar stage, they'd be very easily missed to someone like me.
