One of the most fascinating things I’ve learned in the last few years is the process of a caterpillar in a cocoon. I had always thought of the couple of weeks a caterpillar spends there as a little nap while their body sprouts wings, and that is the furthest thing from the truth.
After eating copious amounts of leaves and growing to the maximum, a caterpillar forms a cocoon around themselves in order to become a butterfly. Once inside, the caterpillar literally splits its skin apart, and then its own digestive juices digest and liquefy its body. Inside the cocoon, it is just goo—nothing remains of its old structure other than the liquefied, digested slime. Then, the cells reform as an entirely new being.
When the butterfly finally works its way out of the cocoon, it has been completely transformed in what has to be one of the ickiest processes. It comes out beautiful, but, man, did it ever go through it to get there!
