Cribellar silk-combing and line-adding behaviours of the North American spider Filistatinella domestica Desales-Lara, 2012 (Araneae: Filistatidae)

Abstract

Abstract We report for the first time the combing and adding behaviours of cribellar threads by the prithine filistatid Filistatinella domestica. The spiders combed cribellar silk using a leg IV resting on contralateral leg III as in other filistatids. Once it was combed, they added the cribellar thread as has been reported for some members of Filistatinae, the other subfamily of Filistatidae, rather than as in other prithines.
