The larvae feed on Stinging Nettle and Pelitory of the Wall, continually brooded with the adults resting up during the winter and flying on mild days. Larvae and pupae will also overwinter.The leaf containing the ova should be placed on potted Nettles and allowed to hatch. The larvae will make a tent in the tips of the Nettles and will not be visible until they become larger. Larvae are liable to catch a virus if they are left on old Nettles in water.Only suitable for experienced breeders.
