The results of research on the predatory epigeic macrofauna of eight habitats in the Kampinos National Park near Warsaw are presented in this study. The first part of the study is devoted to an analysis of communities of wandering spiders, giving variations in their penetration during the season and during the day. The second part of the study is concerned with the relations between spiders and other groups of epigeic predatory Arthropoda. It was found that these relations are competitive in type. In the spring the wandering spiders are the earliest of all predators to appear on the surface of the soil. In forest habitats they exhibit a tendency to seasonal alternation with Carabidae. They also exhibit differences in the time of their occurrence, dividing the season between the group of large and medium body-sized species. During the day they usually altemate with Opiliones and Carabidae. The fewer the ants present on meadow stations, on the other hand, the more intensively the spiders occupy these stations.
