A Measuring Worm

Richard Wilbur (2008)

This yellow striped green
Caterpillar, climbing up
The steep window screen,

Constantly (for lack
Of a full set of legs) keeps
Humping up his back.

It’s as if he sent
By a sort of semaphore
Dark omegas meant

To warn of Last Things.
Although he doesn’t know it,
He will soon have wings,

And I, too, don’t know
Toward what undreamt condition
Inch by inch I go.
