This book is aimed at anyone who is committed to the preservation and protection of nature. If today's collector is no longer solely focused on filling a display case with colorful butterflies, but is instead striving to understand the diversity of species, then they are also entitled to catch and prepare individual specimens from animal populations in order to identify them accurately. Only in this way can they gain important insights into the population ecological relationships in nature and competently participate in conservation measures. The author has compiled his decades of experience from zoological excursions in this practical book. In addition to instructions for catching insects, spiders, crustaceans, and other animals, it also provides guidance on their breeding and care, as well as on their proper preparation and storage.
