The Digger and the Butterfly by Joseph Kuefler

Digger and the other big trucks work all day, smashing and building and transforming their job site. But when a caterpillar weaves its cocoon onto Digger’s bucket, he is forced to stop and be still. In the stillness, Digger begins to notice the world beyond his worksite. And when the butterfly finally emerges, it’s clear that Digger and his friends have also been changed forever.

This book will include back matter which illustrates the stages of metamorphosis for young readers.
