紫斑蝶，一種到處都可見的蝴蝶在台灣，是那樣的平凡可見群蝶飛舞的紫蝶幽谷，更是沒人知道它確切的數量在世界上，與墨西哥帝王斑蝶並列世界兩大越冬型蝶種，雖然它不像一些瀕臨絕種的動物那麼迫切的需要被保護，但近幾年來已經至少有十餘處的紫蝶幽谷消失不見一個蝶谷的消失，代表一處自然生態的失衡，假如有一天平凡的紫斑蝶消失在你我的世界對台灣自然生態的衝擊之大是無法想像的可見，紫斑蝶的生態保育，雖然不是迫切，但卻勢在必行.讓我們一起守護這台灣的紫色寶藏~紫斑蝶吧！
The purple crow butterfly, a kind of butterfly that can be seen everywhere in Taiwan, is such an ordinary valley where you can see butterflies flying around, and no one knows the exact amount of it in the world. It ranks with the Mexican monarch butterfly as the world's two largest overwintering butterfly species. Although it is not as urgent as some endangered animals to be protected, in recent years, there have been at least a dozen purple butterfly valleys that have disappeared without a single butterfly valley disappearing. It show the imbalance of a natural ecology. If one day the ordinary purple butterfly disappears in your world, the impact on Taiwan's natural ecology will be unimaginable. Although the ecological conservation of purple spotted butterfly is not urgent, it is imperative. Let's guard this purple treasure of Taiwan together --The purple crow butterfly!
