What does "better self" mean to caterpillars?

For caterpillars, "better yourself" in the text means growing up to be a butterfly; For a small seed, "better yourself" in the text means (growing into a towering tree).

Caterpillar can become a butterfly, but it takes a long process and a lot of pain to become a butterfly.

The process by which a caterpillar becomes a butterfly;

The life cycle of a butterfly is generally nine months, but it does not always exist in the form of a beautiful butterfly. Its growth process is a cycle, from egg to caterpillar to pupa to butterfly to egg.

1. Generally speaking, this cycle starts with a small egg. These eggs are usually attached to the back of leaves of some plants.

2. The eggs can hatch into caterpillars within 3-6 days after laying. The newly hatched larvae are so small that we can hardly find them with the naked eye. However, caterpillars eat very hard after birth and grow very fast, which will be 100 times larger than when they were born. A caterpillar has eight pairs of feet, and the first three pairs of feet will become the feet of a butterfly.

3. The caterpillar needs to molt five times in its life, and it will grow much bigger after molting each time, so will the snake. When the caterpillar grows up, it will leave the leaves and find a safe place to hang it in the shape of a J and a cocoon. What is inside the cocoon is called pupa, which is generally more than three centimeters long. Different kinds of butterflies have cocoons of different colors, and some cocoons are transparent. We can see the pupa slowly changing color in the cocoon.

4. After 9~ 14 days, the pupa becomes a butterfly in the cocoon and begins to break out. Butterfly wings are wet and soft when it first emerges from cocoon, but it can fly in an hour. In this way, the caterpillar turned into a beautiful butterfly, completing a cycle of life.
