|Title:||Prey capture and spatial distribution of Philoponella vittata (Araneae Uloboridae) in host webs|
|Abstract:||The individual spatial position in spider colonies may influence foraging success and predation risk. Philoponella vittata form aggregates using other spider's webs as support for their small orbs. In this study we investigated the individuals' spatial distribution relative to their size, the relation between spider abundance and success of prey capture, and the frequency of individuals capturing prey in central and peripheral positions, in webs constructed by four host species. Smaller individuals were found mainly in the peripheral positions and, in central positions, small and large individuals occurred in a frequency that was, respectively, lower and higher than the expected. The percentage of spiders consuming prey, however, had no relation to spider density and position. This suggests that the distribution pattern could be determined by factors other than food availability, such as the avoidance of parasitism and predation.|
