This paper presents the results of a 3 years' survey of the spider fauna of alfalfa fields and their field margins in South Hungary. During the study samples were taken by pitfall trap, sweep net and suction sampler (hand-held D-vac). The studied alfalfa fields and their margins had a diverse spider community. The overall community structures at both sites and at both habitat types were rather similar, which, we suggest, reflected the moderately disturbed state of these habitats. The communities were dominated by few super abundant species. Pardosa agrestis, the most common species, together with few other common species were more abundant in alfalfa, but occurred frequently in the margins, as well. Many of the moderately common species, on the other hand, were either associated with alfalfa or with field margin. Spider densities as assessed from suction sampling were high throughout the study period in both habitats. Average density of spiders in the alfalfa was 85 indiv./m2, and 184 indiv./m2 in the margin.
