Like that ecological marvel in Mexico, in Taiwan, on the other side of the Pacific Ocean, in such locations as Kaohsiung's Maolin, Pingtung's Wutai, and Taitung's Mt. Tawu, great numbers of crow butterflies also come south in November before winter, settling in valleys where they can shelter from the wind and feed on nectar plants.
相當於墨西哥這場生態奇觀的，就在太平洋的另一端台灣，包含高雄茂林、屏東霧台、台東大武山區，每到冬天來臨前（11 月），也會有大批紫斑蝶陸續南來，群聚於有蜜源植物和地形足以避風的山谷。
