One morning, a citizen was walking in a country park and accidentally saw a pupa on the branches of a small tree, trying to break free from its cocoon. So, he didn't go anywhere the whole morning, but stood by and curiously observed the whole process of the moth "breaking out of the cocoon". After a while, the moth was seen struggling hard in the cocoon. On the surface, it seemed that it could not escape the shackles of the cocoon, and it seemed impossible to get out again.

Finally, the kind-hearted and interested man lost his patience. He took out his small scissors and cut a small hole in the top part of the cocoon to make it easier for the moth to get out of it. Sure enough, within a few minutes, the moth finally got out easily and lay on the branch. Its body suddenly became very bloated, and its wings seemed a bit shrunken.

Unfortunately, the moth that received help was not only unable to fly in the air and show its beauty, but could only crawl slowly on the ground, and died after a while.

It turns out that when moths pupate, their wings are atrophied and underdeveloped. They must struggle for a while before the body fluids in the body can flow into the wings. Later, the two wings can spread powerfully in the air. fly.

The kind-hearted citizen, according to his own will, helped the moth emerge from the cocoon, but he caused the moth's tragedy.
