HabitatThis butterfly prefers forests and woods. It frequents river valleys. It occurs at low elevations (1,000 to 5,000 feet (300 to 1,520 m)) in north east India but is found at higher altitudes in the western extent of its range – up to 11,000 feet (3,400 m) in Kashmir. HabitsThis butterfly has a leisurely flight high above, but is easily recognisable by the thin long forewings and hindwings. It is attracted to flowers and visits Clemanthe, Buddleia, Lantana and Rhododendron blossoms. It is mimicked by a day flying moth Epicopa (or Epicopia) polydorus, which flies at the same period and over the same range as the common windmill and has much the same manner and habits. Life cycleThis species has several broods where it finds suitable climate. It is seen on the wing between April and September. The imago has a foul odour. Food plants
