[Daily Photo] Question Mark Buttterfly / 長尾鈎蛺蝶

I saw this Question Mark (Polygonia interrogationis) Butterfly while I was walking along a trail in Matthaei Botanical Gardens of the University of Michigan (in Ann Arbor, Michigan). I was lucky to find it because when it closed its wings, it looked exactly like a dry leaf. I tried really hard to find one with its wings closed, but I never succeeded.

我在野外的步道上遇見這一隻長尾鈎蛺蝶，其實他是一種枯葉蝶。我很想也順便拍一張翅膀合起來的照片，但是我怎麼樣都找不到，他的擬態實在太厲害了。
