The park's varied vegetation has nurtured a rich variety of butterfly species which have in turn attracted many scientists and specialists. So far, more than 174 species of butterflies in five different families have been recorded. Every summer, when the Eupatorium shimadai blooms, many milkweed butterflies begin gathering together, followed by other butterfly and insect species. The butterflies indulge in the beauty of the flowers and their nectar, which is a fantastic sight attracting many nature lovers every year. Though there are vast amounts of butterfly species, they are easily identifiable by sight, and their ecology is closely linked to the environment. Understanding butterflies is a great way to get closer to nature and is also the best way to evoke empathy for nature.
