Hestina assimilis formosana is a subspecies of Hestina assimilis. It is a medium size butterfly in the family Nymphalidae found in Asia such as the Korean Peninsula, Southeast China, Northern Vietnam, Taiwan, and Amami Island. In August 2022, I saw this beautiful but lifeless Hestina assimilis formosana on the balcony of the place that I stayed in Taiwan. Although I could clearly see it and take a good picture, I felt sad.
紅斑脈蛺蝶 (其他別名: 紅星脈蛺蝶, 紅珠蛺蝶, 紅星斑挾蝶, 紅星擬斑蛺蝶, 紅星胡麻斑蛺蝶, 紅星斑蛺蝶, 紅環蛺蝶, 黑脈蛺蝶) 是 Hestina assimilis 的亞種。它是蛺蝶科的一種中型蝴蝶，分佈於亞洲，如朝鮮半島、中國東南部、越南北部、台灣和日本奄美大島。2022年八月在臺灣住處的陽台上看到這隻漂亮但無氣息的紅斑脈蛺蝶，雖然能夠清楚的照到它，但心中為它傷感。
