This is the first comprehensive photo-illustrated guide to the caterpillars of butterflies and macro-moths. The book illustrates over 850 different species, or about 95% of resident, extinct, regular or irregular immigrant species to the British Isles. All specimens are photographed in natural situations upon the relevant foodplants, including many varieties indigenous to continental Europe. Many of the species have never been illustrated as caterpillars before, either by artwork or by photography. This work has received unreserved support from the best and most competent entomologists. Though the book illustrates British species, it is most valuable for lepidopterists all over Europe and especially in North and Central Europe. Never before have so many superb colour photographs of Lepidoptera been brought together in a book. After Preface, Acknowledgements, Introduction, and List of larvae required for photographs, the systematic part with descriptions of the species follows. The text is for each species divided into the following chapters: Larva, with description; Foodplant; Habits, incl. information on how to breed the species. The book should appeal to anyone with an interest in European Macrolepidoptera.
