Giant Swallowtail Butterfly
PUDDLING
When a butterfly lands on the ground and sips water from a puddle, it is called puddling. At the muddy or sandy puddle (often located near animal dung), the butterfly sips water rich in mineral salts and other essential nutrients (mostly sodium chloride and nitrogen-rich solutions) that have leached from the surrounding soil and rocks. Male butterflies do more puddling than females. The dissolved salts and minerals may be used to make pheromones (that the male uses to attract females) and sperm.
