But it is not dead. It is turning into a creature that has wings and legs, and can fly and walk.
As the fly lies in its case, first the legs and then the wings grow. It gets a head with mouth, eyes, and a trunk or tube, and from a poor worm it turns to a wonder, as you will see.
But in its little coffin it is shut close, and its legs and wings are all bent up. In a few days the change is made. Now it is ready to come out.
It moves, and pulls, and gets free from the hard case. Then it strikes the end of the case with its head time after time. At last it breaks the case open, and out comes the fly!
Then it stands in the air, and in the sun if it can, and shakes itself. It is cold and weak; but the air dries its wings and blows out the wrinkles.
In a very few minutes the fly is strong and gay.
Then it spreads its wings and sails off to enjoy its life, and to look for something good to eat.
