Purple Crow Butterfly is one of the only two kinds of overwintering butterflies in the world. When the northeastern monsoons blow, they go to mountain valleys in southern Taiwan where it is warm to spend the winter. When the spring arrives, they follow the footsteps of the spring, returning to places in the North to breed the next generation. They die when the temperature goes under 4 Celsius degrees.
Since 2009, the Siraya National Scenic Area Administration has been working with conservation groups and schools to grow nectar plants for butterflies in Hongye Park of Guanziling through educational events, so as to make the park an ideal place for butterflies to stay. As a result, today, the park has become one of the most densely populated places of Purple Crow Butterfly, and as many as 116 other butterfly species can be found in the park. Now, every year at the turn of spring and summer, visitors can appreciate dancing butterflies all around the park.
At a recent event, about 2,000 plants of “Kusukusu Eupatorium,” a kind of orchid, were grown to keep the park the home of Purple Crow Butterfly. This well responds to the Ministry of Transport and Communications and the Tourism Bureau of MOTC’s key policy, “making Purple Crow Butterfly Taiwan’s tourism highlight.” The Administration looks forward to contributing more to the conservation of Purple Crow Butterfly.
