Common Banded Peacock (Papilio crino)

Common butterfly flies all over the island up to about 1000m asl. It is more common in the dry zone. Common Banded Peacock is a migratory butterfly and Ormiston recorded an interesting observation of large flight of these butterflies continues 3-4 days straight out to the sea at Galle. He believed that enormous numbers of  them must have perished in the sea (Ormiston  W., 1924). Male Common Banded Peacock often settles on mud patches and river beds to absorb minerals. Its larva feeds on Chloroxylon swietenia[Satinwood/බුරුත], Clausena indica [මීගොං කරපිංචා] and Toddalia asiatica[කුඩු මිරිස්]
