Is it a worm? Is it a snake? No! It’s a caterpillar . . .

In the latest addition to KEVIN MCCLOSKEY’s beloved Giggle and Learn series, young readers will explore how caterpillars morph into the many different moths and butterflies that help pollinate our world. Growing up is scary, but caterpillars can lead the way!
