Zygaena purpuralis is a medium-sized moth with a wingspan reaching 30–34 millimetres (1.2–1.3 in). Usually the forewings show three bright red longitudinal streaks quite variable in shape, with almost transparent greyish-bluish edges. Hind wings are more extensively or almost completely bright red. Head and thorax are black, while the abdomen is dark blue. Adults moths are on wing from late May until August, depending on location. They fly during the day, especially with warm and sunny weather, feeding on nectar of various flowers. Source: Wikipedia
