First there's a tiny egg on a leaf, then a caterpillar hatching, just big enough to see—follow along as the caterpillar munches at the leaves, growing and shedding layers, then spinning a thread into a green and golden chrysalis, and finally transforming into a butterfly. Ideal for sharing with prereaders, this book not only describes metamorphosis in simple sentences, the petal-shaped pages fold out one by one to become a big, flower-shaped display.
