Abstract: Data are given concerning stratification, phenology, feeding and mating behaviour of the theridiid spider Dipoena torva (THORELL, 1875). The species was found predominantly at heights of around 10 metres on the stems of oaks and pines in Berlin, Germany. The sex ratio was more or less 1:1. Adult spiders were active during summer whereas juveniles were onliy found before and after the main activity period of adults. This species seems to be active during the daytime. The main food consists of ants. The mating behaviour is described. The occurence of D. torva is a result of certain biotic and abiotic factors such as the abundance of ants, the understorey and structural factors.
