狼蛛跟踪或伏击猎物，而不是建立捕食网。石松科植物的蛛丝在通过气球传播的空中传播过程中很重要（Richter，1970 b），在某些情况下，在猎物固定后的包裹过程中（Rovner和Knost，1974），以及卵囊或精子网的构建过程中（Richter，1970 a）。在运动过程中，两性都放下了丝拖绳，通常认为这些拖绳具有稳定或安全功能（Richter和货车der Krann，1970）。此外，雌性拖丝会诱导雄性同种的求偶行为，在某些物种中，据报道雄性会跟随雌性的踪迹，但尚未尝试对拖丝跟随行为进行系统分析（Bristowe和Locket，1926; Engelhardt，1964; Kaston，1936）。本文研究了雄性狼蛛Lycosa rabida和L.有斑点的。调查的具体领域包括确定使用的各种附属物在以下，分析线索参与启动和维持trail-following，和trailfollowing行为的种间比较。
Wolf spiders stalk or ambush their prey rather than build preycapture webs. Production of silk by lycosids is important during aerial dispersal via ballooning (Richter, 1970b) and, in some, during post-immobilization wrapping of prey (Rovner and Knost, 1974), and construction of egg sacs or sperm webs (Richter, 1970a). During locomotion both sexes lay down silk draglines that are generally assumed to have a stabilizing or security function (Richter and Van der Krann, 1970). In addition, female draglines induce courtship behavior in male conspecifics and, in some species, males are reported to have followed a female trail, but no systematic analyses of the dragline-following behavior have been attempted (Bristowe and Locket, 1926; Engelhardt, 1964; Kaston, 1936). The present study is concerned with the trail-following behavior of male Lycosa rabida and L. punctulata. Specific areas of investigation include determination of the use of various appendages during following, analysis of cues involved in initiating and maintaining trail-following, and an interspecific comparison of trailfollowing behavior.
