WHERE BUTTERFLIES GROW

In a field of lacy leaves, a small caterpillar hatches, grows, and sheds its skin, becoming a smooth, green creeper. It eats and changes some more, then in a sequence of remarkable close-ups, spins a sliken sling in which to pupate--until it finally bursts forth as a brilliant black swallowtail butterfly. Includes suggestions on how children can grow butterfiles in their own gardens. Color throughout.
