The milkweed butterflies, indigenous to Taiwan, migrate in late March from Southern Taiwan to the north, where they lay eggs and die. The young butterflies then fly south every November to a warm mountain valley near the Southern part of Taiwan. Conservationists say Taiwan has about 2 million milkweed butterflies.

To protect the migrating butterflies, a 600 meter stretch of highway in Southern Taiwan’s Yunlin County will be sealed off in the coming days as the migration peaks. Authorities set up nets to make the butterflies fly higher and avoid passing cars. They will also install ultraviolet lights to guide the insects across a highway overpass.
