The family lepidoptera, surveyed here by the author of two bird books (Our Amazing Birds and How to Attract the Birds) carries a strong interest in nature to further fields. First there is the description of the family and its archeology. Then body organization, outside and in, prepares the way for an account of the growth cycle and the mysterious and fascinating transformation from caterpillar to winged insect via the cocoon. Explanations of the differences between moths and butterflies, most strikingly the position of the wing, background more explicit detail on the different kinds of each. With last chapters on ways to study and collect one's own moths and butterflies, this contains valuable information for the interested.
