This book will enable the identification of each of the 57 species of butterfly that has been recorded from the Cayman Islands. There is a description of every butterfly, stressing its most important characteristics, with photographs of living and mounted specimens. The distribution, history and biology of each species are reviewed and the plants which provide adult butterflies with nectar or feed their caterpillars are tabulated. A general introduction includes a discussion of the affinities and size of the Caymanian butterfly fauna. The three islands share most of their butterfly species but each island has uniquely characteristic elements and five subspecies live only in the Cayman Islands. Knowledge is fundamental to conservation; it is hoped that both the casual butterfly watcher and those more committed to the study of butterflies will discover much of interest in this book and thereby make a contribution to the continuing survival of these beautiful insects.
