BBC 雲林紫斑蝶遷移報導 the migration of purple butterflies



Taiwan Purple Butterfly Valley



Purple Butterfly Valley is not a specific geographical name,but a term used by butterfly researchers to represent the biological phenomenon of Euploeini butterflies overwintering en masse. Every winter, it is conservatively estimated that at least a million Euploeini butterflies glide on purple wings to the holy mountain of the Rukai and Paiwan Tribes in south Taiwan, Maolin, and take shelter in warm valleys at the foot of Dawu Mountain. About six hundred thousand butterflies winter in "Purple Butterfly Valley", which along with the Monarch butterfly's winter home in Mexico is one of only two mass wintering sites known in the world.
