These little beasties were on some ragwort growing in the church grounds. They are the caterpillar of the cinnabar moth, a beautiful day time moth which you might see flying around the church gardens if you watch carefully.
These creatures have fascinating behaviour including being poisonous to some predators and also being cannibals! You can find out more about them on Wikipedia or many other good websites
