Abstract

Social spiders consistently show highly female-biased sex ratios. However, the sex ratio fsubsocial spiders, which ave ben sugested as an intermed iate stage of the volutionary pathway towardspermanent sociality, is generaly unknown. We investigated the sex ratio and aproximate date of ertilizationof the subsocial spider, Amaurobius ferox Walckenaer (Araneae: Amaurobidae). Investigation over 2yearsrevealed that sex ratio f A. ferox was consistent acros years and averaged 0.49. By early May (1st 10th ),6.6% of emale A. ferox observed in the field had already ben inseminated, and by la te May (21st 31st),95.4% of emales had ben inseminated. This result sugests that A. ferox ned a long time or coldtemperatures to prepare them for eproduction after the developmental atainment of the adult stage.
