The balcony observer's 297th report- Alien doll undress (My NO.20 butterfly) 外星娃娃脫衣

by Tsao T-F April. 24, 2021 186 views

After several hours of anxious travel (usually at night), the final instar larvae of Lemon Butterfly (Papilio demoleus) will choose a place to transform. Before transforming, it will spit silk (tens of minutes), and then fix itself with silk thread. After resting for dozens of minutes, it arched its back, hung hands and feet, and entered the "pre-pupal stage" (it is usually in early morning, for example, 5 o'clock in the morning).

經過數個小時焦急的旅行後(通常發生在晚上),無尾鳳蝶的終齡幼蟲會選定一個地方進行變身。變身前會吐絲(好幾十分鐘),之後用絲線固定好自己。休息幾十分鐘後,弓起他的背,手腳懸空,進入"前蛹期"(這時通常已是清晨,例如早上五點)。

How do I know that it has just entered the pre-pupa stage? Because the silk (arrow) that it just spit out has been noted, and its hands and feet have not left the leaves. 我怎麼知道牠剛進入前蛹期呢?因為牠剛吐出的絲(箭頭處)已經被我發現了,而且牠的手腳還沒有離開葉子。

I think it is like a cute alien doll. 我覺得他像一隻可愛的外星娃娃。

After waiting for 18 +/- 2 hours (for example, 11 o'clock in the evening), it twists the body to take off the skin of the larva (it only takes a few minutes) to form a green (or wait tens of minutes before turning into a brown) pupa.

靜待十八加減二小時左右(例如晚上十一點),扭動身體脫掉幼蟲的皮(只花幾分鐘),形成綠色(或等幾十分鐘後再轉變成褐色)的吊蛹。

After about 18 hours, the skin has floated a bit, and the color has become mottled, indicating that it is about to transform. 過了十八小時左右,皮膚已經有點浮起,顏色因此變得斑駁,表示牠即將要變身了。

It looks like you open a zipper of a skin-tight garment behind the neck, the pupa emerged. 就像你從脖子後面的地方把緊身衣的拉鍊打開一樣,蛹於是冒出來了。

After a minute of twisting, the skin-tight garment fell to the waist. 過了一分鐘的扭動,緊身衣褪到腰。

After another minute of twisting, the skin-tight garment fell to the tail. The baby of Lemon Butterfly has entered the pupal stage. 再過了一分鐘的扭動,緊身衣褪到尾巴了。無尾鳳蝶寶寶進入蛹期了。

Which came first? How did this transformation evolve? How does it know what to do next? Wish I could talk caterpillar. Great documentation and it should be in a book.

Thanks, Leon. Maybe all the things of a caterpillar are presented by instinct. And if you want to edit a book, I would like to donate my photos to you in free. Haha!
