The monarch butterfly, one of the most seemingly delicate of all of nature’s animals, proves to be one of the toughest in this reader.

Making the yearly trip from the Northern United States and Canada to the Oyamel forest of Mexico is no easy task, and it takes five generations of butterflies in order to do so.

Battling cold temperatures and the threat of starvation, these beautiful insects complete an almost 3,000 mile journey over the course of two months, only to have to turn and around and head back home


帝王斑蝶看似是大自然界裡嬌弱的物種，其實不然，本書將告訴你，帝王斑蝶其實是世界上最強悍的物種之一！

每一年，帝王斑蝶從北美洲與加拿大長途遷徙至位於墨西哥的歐亞梅爾杉林，這項任務可不簡單，牠們經歷五個世代的輪替才能完成遷徙。

美麗的帝王斑蝶必須戰勝寒冷氣候與飢餓，費時兩個月完成三千英哩的旅程，一抵達目的，沒待多久，又得啟程回家。
