Butterflies in Taiwan
這張生態圖裡的蝴蝶是大綠弄蝶,身體圓嘟嘟,又多毛,常被誤以為是蛾類。其實,弄蝶科的蝴蝶屬於小至中型蝴蝶,外觀和長相介於蝴蝶和蛾之間;而且觸角未端彎曲呈鉤狀,不同於其他類的蝴蝶。
大綠弄蝶下翅尾端有橙紅斑點,為什麼長得有點像頭部,而且更寬闊明顯呢?
解說:演化產生的尾部斑點,使得天敵以為是頭部,遭到襲擊時,可以讓弄蝶有時間逃跑!

The butterfly in this illustration is an Indian awlking (Choaspes benjaminii); due to its plump and hairy appearance, it’s easily mistaken for a moth. What readily distinguishes it from a moth is the curve at the end of its antennae.
The Indian awlking has orange-red spots on the posterior section of its hindwings, which have the appearance of a head. What for?
Answer: Having a false head on the posterior section of its hindwings confuses predators, thereby increasing the butterfly’s chances of escaping.
