Overall, a monarch butterfly is no more or less striking than its host, the milkweed pod.(總的來說，帝王蝴蝶和其宿主奶草豆莢的漂亮程度是差不多的，既不多一分，也不少一分。)

The Monarch Butterfly breathes through its wings and female Monarchs have thicker wing veins.(帝王蝶通過翅膀呼吸，雌性帝王蝶有更加厚實的翅膀脈絡。)

I thought to myself. "this is the most unusual looking butterfly." I have seen Monarch butterflies up close, but never one like this before.(這是外表最為奇特的蝴蝶了，我以前仔細的觀察過帝王蝶，但是從來沒有見過這種的。)

The monarch is one of the few butterfly species that make a migratory trip.(金蝴蝶是一種很少見的進行遷移的蝴蝶種類。)

Mature butterflies retain the glycosides in a mature monarch butterfly could be used to determine its place of origin.(成熟的蝴蝶在成熟的黑脈金斑蝶體內保留糖苷，可以用來確定其產地。)

In defending itself so thoroughly against the monarch, the milkweed became inseparable from the butterfly.(馬利筋為自我保護如此認真地抵抗黑脈金斑蝶的侵襲，結果變得與蝴蝶難舍難分。)
