The over wintering Peacock butterfly laid its eggs on the upper leaves of the stinging nettles at 50˚47’10.29″ N x 1˚24’26.60″ W and they are all now hatching. The caterpillars eat on the leaves through five stages of growth, moulting their skins with each ‘instar’ and protecting themselves from predators by weaving communal silk tents. Soon they will pupate and I shall be on the lookout for the chrysalis.
