A very beautiful book that besides all macromoths also covers the micromoths traditionally collected by macro-lepidopterists such as Hepialidae, Sesiidae, Zygaenidae etc., totally 958 species. For each species a short tex divided in the chapters Identification, Distribution, Larva, Imago and further there is a map to each species of the Norwegian distribution. All species are illustrated on the 163 colour plates, most of them slightly enlarged, which helps identification of especially the smaller species like the genera Idaea and Eupithecia.
For each family a short introductionary chapter supplemented with some extremely beautiful colour photos of live butterflies and moths, often covering a whole page. The book has further short chapters on Lepidoptera, Habitats, Distribution patterns, How to study and collect Lepidoptera, Classification, Nomenclature. Both the photography and printing quality in this book is very good and can probably not be done better.
