The aim of the book is to introduce the Hungarian speaking reader in the diversity of the butterflies inhabiting the globe. To do this, the book uses one hundred color plates of Otto Staudinger’s classic monograph on exotic butterflies, published at the end of the 19th century. The species considered by the German author to be representative of the most characteristic genera are displayed on the plates in their original size, splendor and colour. The introductory chapters discuss the various butterfly families, listing the Latin and Hungarian names of the taxonomic categories, with a brief description of the latter. The 1,360 specimens depicted on the hundred plates represent 1,245 species. The scientific names, distribution, and host plants of their caterpillars are given in a separate chapter. In this chapter the reader will also find the current taxonomic status, nomenclatural combination and classification for each species. After the section of the magnificent coloured plates, the scientists who discovered and described butterflies are discussed in a nutshell via their short biographies. The practical use of the book is provided by alphabetical indices for genus- and species group names, and the names of the larval hostplants.
