TAIPEI — Massive flocks of purple crow butterflies swarmed from Kaohsiung Friday,

heading north during their regular migration and prompting freeway authorities to close the outer lane of a section of freeway No. 3 in southern Taiwan to protect the creatures from vehicles traveling at high speeds.

The butterfly migration began in sunlight after several days of rain, with more than 900 purple crows per minute observed flying from Kaohsiung’s Maolin District, home to the Maolin National Scenic Park, toward the north, according to the Taiwan Purple Crow Butterfly Ecological Preservation Association.

Because Linnei Township in Yunlin County is one of the key rest stops for the migrating butterflies, the Taiwan Area National Freeway Bureau closed the northbound outer lane of the freeway No. 3 Linnei-Tsukou section at around 11:30 a.m. to protect the insects as they crossed the road.    [FULL  STORY]
