Written by one of Australia's leading lepidopterists, the book is stunningly illustrated with colour photographs, many of which are new, of each of the 435 currently recognised species. There is also a distribution map and flight chart for each species on the Australian mainland, together with information on similar species, variation, behaviour, habitat, status and larval food plants. The introduction to the book covers adult structure, higher classification, distribution and habitats, as well as life cycle and behaviour. A new chapter on collecting and preserving butterflies is included. There is also an updated checklist of all species, a glossary, a bibliography and indexes of common and scientific names.
