From egg to caterpillar to butterfly! This simple science book is perfect for Spanish-speaking new readers and young Spanish language learners. A caterpillar hatches, eats, becomes a pupa, weathers storms, and grows into a butterfly before flying away. An elegant, beautifully illustrated life cycle book that kids can read on their own while learning basic Spanish language science vocabulary. A chart in the back of the book shows the nine stages of the black swallowtail butterfly's development.
