Structure and Function of the Web of Bathyphantes simillimus (Araneae: Linyphiidae) in an Isolated Population in the Stołowe Mountains, SW Poland

Summary Bathyphantes simillimus inhabits deep sandstone rock crevices. Field and laboratory observations of juveniles and adults showed four web structures and two related, completely different, prey capture strategies. The original function of the web occurs only in the young. Communal webs are reported for the first time in a linyphiid. The disparity of web structures and prey capture strategies proves behavioural flexibility in B. simillimus; additionally it shows that this species is able to adjust to the type of dwelling site, as well as to the type and number of prey. Data on the prey spectrum, abundance both of B. simillimus and its prey, and a comparison of the population densities of B. simillimus and another linyphiid species are also presented.
