The purple emperor is a large brown butterfly with iridescent wings that shine blue or purple in the light. Purple emperors do not feed from flowers. Instead they feed from honeydew secreted by aphids, and even from dung and rotting animal carcasses. Their caterpillars feed on pussy willow (sallow) plants.
