Before a butterfly emerges from its cocoon, it is a caterpillar. A very ugly caterpillar, crawling slowly on the ground, not daring to attract anyone's attention, not daring to dream of turning into a butterfly. Until he appeared, he gave the little bug a chance to transform, but he failed to see the bug transform into a butterfly and spread its wings to fly high.
But the insect did not transform into a colorful butterfly as the man wished, but turned into a black butterfly, a beautiful but dangerous butterfly.
