I am the prettiest of them all.

More colours than the rainbows have I,
With a myriad of designs on my wings,
Four of them for me to flit and fly,
From flowers to flowers and natured things.

I was not born beautiful at dawn,
A crawling caterpillar was my start,
But like ugly duckling and the swan,
I was transformed into a piece of art.

I am the prettiest of them all.
