372 DUNÁNTÚLI DOLGOZATOK (A) TERMÉSZETTUDOMÁNYI SOROZAT 11. (2002) 12. The caddisflies of Hungary (Trichoptera) Summary The species number of the total Hungarian fauna runs up to 32-33 thousand. Of them only 210 caddisflies (Trichoptera) are known today (0,6 p.c.). At least 10 thousand caddisfly species have already been described worldwide, and the discovery of further thousands are to be expected. Sometimes new species are found also in Europe mostly through the revision of certain groups (e.g. Hydropsyche), but new species are also collected and described by field works done in less intensively examined areas. Contrary to the relative small number of species, the total biomass of these insects are determining in each water body. Most of the species are rather sensitive to the ecological factors, therefore their occurrence and dominance is characteristic for the biotopes. A hundred years ago our knowledge was rather incomplete on caddisflies of Hungary (Fauna Regni Hungáriáé, MOCSÁRY 1900). In that most important work of the turn of the century only 150 species were listed, most of them outside the recent area of Hungary, or from only one or two sites. Although a bulky volume was published in the series of Fauna Hungáriáé seventy years later (Steinmann 1970), this work was not helpful in getting acquainted with the Hungarian fauna more thoroughly, as 48 species were enumerated wrongly, other 51 species were listed as “species to be expected” - with these mistakes the author listed 157 extant species from Hungary. In this book - appearing as Volume 11 of Studia Pannonica (A) Series Historico- naturalis (Dunántúli Dolgozatok (A) Természettudományi Sorozat) - we intend to summarize all our current knowledge on Hungarian caddisflies (Trichoptera), both on the basis of literature data and based on our own twenty-year-long field work and elaborations. The book consists of twelve main Parts, including this Summary. The first four chapters form the General Part, and Chapters 5-8 give a detailed discussion of the results on faunal findings, biotopes, ecology, zoogeography and conservation biology. In Chapter 1 (Introduction: Aim of the work, Acknowledgements) we outline the main aim of this work: to actualise and summarize our knowledge about caddisflies occurring in Hungary as it is said in the first paragraphs of this chapter. In the Acknowledgements we express our thanks to all the persons and institutes who or which assisted us in this gigantic work. Here, in the English text we repeat the names of some persons: Dr. S. Újhelyi, Dr. H. Malicky, Dr. J. Tardy and Dr. F. Mészáros who contributed a great deal to complete this work. The Ministry of Environment and its nature conservation authorities, i.e. the national park managements (mostly Aggtelek NP, Duna-Dráva NP, Hortobágy NP) and other institutes have also helped us greatly. Chapter 2 (Biology of caddisflies, main outlines of systematics, distribution and ecology) introduces the outlines of caddisfly systematics and the most recent results of their taxonomy. We write about the structure and biology of caddisflies (predominantly of adults) to orient mostly the non-entomologist. Also in this chapter we give a diagram about the number of known caddisfly species between 1900-2000, and show the rapid
