Nógrádi S. – Uherkovich Á.: A Boronka-melléki Tájvédelmi Körzet és környéke tegzes (Trichoptera) faunája. - The caddisfly (Trichoptera) fauna of Boronka region landscape-protection area and environs

Summary The caddisfly (Trichoptera) fauna of Boronka region landscape-protection area and environs (South Hungary) Sára Nógrádi and Ákos Uherkovich 72 Trichoptera species were collected in eleven sites of Boronka Region Landscape-protection Area and environs during the past few years (1985-1991). The caddisfly fauna of this area became the best examined one in our country as more than 21 thousand specimens (9954 cPcfand 11203 ÇÇ) were captured here. The waters of this area belong to the catchment area of Lake Balaton. Only some short and small brooks running to the North have their source here. Main water courses are Boronkastream, Aranyosi-stream and Koroknai-water. No native standing waters occur in the area only some small forest marshes in alder groves. During the last century some fish ponds had been formed, some of them have grown wild again. During seven years of the examinations four light traps functioned on the area. These traps collected the main part of the total material, more than 15 thousand adults. Very important and large materials were collected by Malaise trap and personally, too. Three species were collected only by daytime sweeping, one species was collected only by Malaise-trap. All data are given in the Hungarian text: the species, their localities, data and number of specimens. Name of collector is not given here: most of the material was captured by light trap and the authors. Some very rare species were taken in the area. Several informations about most of them have been published earlier (see Literature, too). Some rare species are: Oxyethira ßavicornis Pict., Hydroptila dampft Ulm., Hydroptila vectis Curt., Ithytrichia lamellaris Eaton, Limnephilus subcentralis Brau., Phacopteryx brevipennis Curt., Erotesis baltica McL. Some of their distribution maps are given (Fig. 3-9). A special paragraph is given about natural protection of the area. This relatively rich and interesting caddisfly community can be preserved only by the preservation of the waters. Most of the Hungarian small waters are polluted slightly or heavily by agricultural activity, by outlet waters of industry and household. The waters of this area are relatively unpolluted. Thus the rare species of these biotops can survive (e. g. Limnephilus subcentralis Brau., Phacopteryx brevipennis Curt., Ithytrichia lamellaris Eaton etc.).
