To a Butterfly

I've watched you now a full half-hour;

Self-poised upon that yellow flower

And, little Butterfly! Indeed

I know not if you sleep or feed.

How motionless! - not frozen seas

More motionless! and then

What joy awaits you, when the breeze

Hath found you out among the trees,

And calls you forth again!

~ William Wordsworth, "To a Butterfly"
