On the wing, the breeze seduced me.
Newly born to take my flight.
From the darkness I did rupture.
From my prison, wrapped up tight.

Come to rest on petals of brightness.
All can see, my change is cast.
I flutter by in paper lightness.
And my species, they are vast.

Darwin wrote of my pure beauty.
I'm collected, caught in nets.
Forever free to dance my duty.
Never kept as pets.

What am I?
