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"
