But the butterfly's coat of many colors has also endangered it. Tsai worries that there may be rare, undiscovered species that may suffer the fate of the large crow butterfly. Even those butterflies that can still be sighted may one day suffer the tragic fate of being labeled "extinct in Taiwan."
蔡百峻擔心，台灣恐怕有許多稀有蝶種尚未發現，就已像大紫斑蝶一樣悄然消失；即使現有蝶種，不久後也可能遭到在圖鑑上加註「在台灣已消失」的悲慘命運。
