Butterfly effect

Every year, two million milkweed butterflies migrate in late March from southern Taiwan to the north, where they lay eggs and die. In November, the young butterflies make their way to a warm mountain valley near the southern city of Kaohsiung, where they spend the winter.

A 600-yard stretch of highway in southern Taiwan’s Yunlin County will soon be sealed off so that the butterflies will be protected during the seasonal migration. Nets will be placed over the highway to force the butterflies to fly higher than passing cars and ultraviolet lights will be installed to guide the butterflies across the highway overpass.

The largest type of milkweed butterfly became extinct in Taiwan decades ago, so let’s hope Taiwan’s fantastic efforts to protect these migrating butterflies meets with continued success.
