An important new series to cover the entire European fauna of the moth family Geometridae with about 940 species. In this first volume a comprehensive introduction covering all aspects of Geometridology is provided.
The Lepidoptera are without doubt the best known insect order in today’s Europe. Nevertheless there is still a great lack of knowledge in some groups, such as the Geometridae. The northern and central European fauna is relatively well known, but the distribution and bionomics of a number of species are poorly known. This problem is much more marked in southern Europe where no books on Geometridae have been published for nearly a century. Data on the bionomics are frequently unavailable which makes it difficult to assess environmental threats to the geometrid species. Information on distribution is still grossly incomplete and many records have been based on misidentifications. These problems are mainly caused by the lack of comprehensive identification literature.
The geographical area covered in this series ranges from North Cape to Gibraltar and Malta, and from the Atlantic Ocean to the Ural Mountains. Each volume will illustrate the adults of all species, and if possible also subspecies, in photographic colour plates of the highest quality. Sexual dimorphism as well as polymorphism will be illustrated. Most species will be shown at natural size, but some larger groups of small species such as the genera Idaea and Eupithecia will be shown enlarged.
Axel Hausmann was born in 1960 in Munich, Germany and studied biology at the Ludwig–Maximilians-University (Munich) where he graduated in zoology. After obtaining his PhD he has been employed since 1989 at the Zoologische Staatssammlung München, where he is head curator of the Lepidoptera section. Axel Hausmann has published many articles on Geometridae and is regarded as a leading authority on west Palaearctic Geometridae.
