This Comma caterpillar was just hanging itself up ready to pupate on a Hertfordshire Nature Reserve notice board as we went in to do maintenance work on the reserve. It secured itself with its silk. The Comma caterpillar has a large white patch on its side to resemble a bird dropping for camouflage; unfortunately this has over-exposed in the direct sunlight.
