Butterflies starts with the familiar life cycle from egg to adult, mating and egg-laying. Less familiar aspects of the butterfly life are explored such as how they care for their eggs, the surprising things that some caterpillars eat, what happens inside the chrysalis and why there are so many variations in adult wing patters and colour. These and many more questions are raised in this examination of the beautiful creatures, which concludes by considering the threats and opportunities that now face them.
