monarch butterfly

Overall, a monarch butterfly is no more or less striking than its host, the milkweed pod.(总的来说，帝王蝴蝶和其宿主奶草豆荚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.(帝王蝶通过翅膀呼吸，雌性帝王蝶有更加厚实的翅膀脉络。)

I thought to myself. "this is the most unusual looking butterfly." I have seen Monarch butterflies up close, but never one like this before.(这是外表最为奇特的蝴蝶了，我以前仔细的观察过帝王蝶，但是从来没有见过这种的。)

The monarch is one of the few butterfly species that make a migratory trip.(金蝴蝶是一种很少见的进行迁移的蝴蝶种类。)

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脉金斑蝶体内保留糖苷，可以用来确定其产地。)

In defending itself so thoroughly against the monarch, the milkweed became inseparable from the butterfly.(马利筋为自我保护如此认真地抵抗黑脉金斑蝶的侵袭，结果变得与蝴蝶难舍难分。)
