Postřehy z potravní strategie křižáka Larinioides sclopetarius včetně kleptoparazitického chování jeho mláďat. Insights into the feeding strategy of the orb-weaver Larinioides sclopetarius including kleptoparasitic behaviour of its juveniles. Pavouk 56: 10–14 (in Czech, English abstract)
Authors: MUDr. Kryštof Rückl
Species: Larinioides ixobolus, Larinioides sclopetarius, Nuctenea silvicultrix, Nuctenea umbratica
The described parasocial behaviour of L. sclopetarius consists in sharing the frame threads of the webs or “web-carpets”, increased tolerance and hunting without orb-webs. This phenomenon appears as a result of an oversupply of prey. According to my observation, the orb-webs on the upper side of bridges are damaged by the wind during the day, so the spiders hunt prey mainly at night. In contrast, under the bridge, the orb-weavers are active during whole day. I have noticed that juveniles of L. sclopetarius, L. ixobolus, Nuctenea umbratica and N. silvicultrix are able to steal small insects from the webs of larger individuals.
