Metamorphosis brings astonishing and exciting changes to a pair of caterpillar friends, who take pride in being the same--and different. Two caterpillar friends love what they have in common--lots of legs and a talent for chewing leaves into funny shapes. And when it's time to build cocoons, they hang theirs side by side. "Happy metamorphosis," says an older, more knowledgeable butterfly. And it is a happy metamorphosis indeed--for when the two emerge from their cocoons, they can fly! But so much else has changed--as one is now a moth, who flies by night, and the other is a butterfly, who flies by day. How will things work now? Fortunately some things never change--like true friends figuring out a way to be together, and happily flying into the sunset and sunrise.

Have you ever wondered how some of nature's smallest creatures spend their days? Here's your chance to take a scientifically accurate peek into the life of the luna moth (Actias luna). Striking illustrations and lively storyline capture the real life changes for this small animal as it hunts for food, faces its enemies, and interacts with humans. The luna moth is found in forested areas throughout the eastern United States and southwestern Canada. The caterpillars eat the leaves of white birch, walnut, and hickory trees. The adult luna moth comes out of its cocoon in the late spring or early summer in the north. In the south, the moth can come out at any time of the year. As a result, up to three generations of lunas can live in one year. Adults die within a week of mating. They do not have working mouthparts, so they do not eat. Their energy comes from the leaves they fed upon while in the caterpillar stage. The name "luna" means "moon" in Latin. The moth was named after the moon because it is a creature of night. The two long tails are said to aid in making it difficult for bats to target them with their sonar. Luna moths are often attracted to bright lights. Be sure to look for them around outdoor lights.
