Butterflies are all around us. It's hard to believe these majestic insects with impressive wingspans and beautifully colored and patterned wings were once creepy crawly caterpillars. How in the world does this transformation happen? This level 1 Reader gives kids an up-close look at exactly how a caterpillar becomes a butterfly. With bonus information including different types of butterflies and poisonous caterpillars, this reader is one of a kind.

This high-interest, educationally vetted series of beginning readers features the magnificent images of National Geographic, accompanied by texts written by experienced, skilled children's book authors.

The inside back cover of the paperback edition is an interactive feature based upon the book. Level 1 books reinforce the content of the book with a kinesthetic learning activity. In Level 2 books readers complete a Cloze letter, or fun fill-in, with vocabulary words.
