Abstract: 153 spider species were collected in the reedbed of Lake Velence. This is the first faunistical survey about the area. Keywords: Lake Velence, reedbed, spider fauna, floating trap Introduction Reedbeds (Phragmitetalia ) are representative, descending plant communities of European wetland habitats. They provide nutriment, habitat, and shelter for numerous living organisms. They function as natural filters of water and play an important role in the biogeochemical cycle of water. Since the 1960-s importance of the study of European reedbeds has increased primarily because of the disappearance of momentous part of wetland habitats. Therefore the conservational role of reedbeds and reedbed-dwelling living organisms has increased. Major part of their peculiar fauna is habitatspecialist species (e.g. many insects, spiders and birds), thus, after the abolishment of their habitats these species disappear, become rare because they strongly adhere to their habitats and do not find their special living conditions in other areas. 0.4% (40 100 ha) of Hungary is covered with reedbeds. At the largest expansion they occur in our lakes (Lake Balaton, Lake Velence, Lake Fertő). Extands their notability that these lakes belong to the group of Eurasian shallow steppe-lakes, which have the most diverse, most valuable wildlife and they reach their westernmost border in the Carpathian Basin. Previous studies on Hungarian reedbeds were primarily related to the Lake Balaton. In the thirties of the last century Gábor Kolosváry ( KOLOSVÁRY 1930), then János Balogh (BALOGH 1933) carried out investigations in the area. In the first part of the nineties Imre Loksa and István Loksa (1990-1991), as well as Kinga Szathmáry researched the spider fauna of the area ( SZATHMÁRY 1995, comment: results of Loksa et al.'s collection is contained in present paper). Since the nineties Csaba Szinetár has been researching the reedbeds of Lake Balaton. ( SZINETÁR 1993, 1995, 2000, 2004.) Beside Lake Balaton
