反枝银蛛（Argyrodes antipodiana，O .P.剑桥）是新西兰的一种盗寄生虫，在自然界中的主要宿主是一种圆织蜘蛛，学名为Araneapustulosa（Walckenaer）。盗寄生虫对这种宿主的偏爱在夏天比在冬天更强烈。在实验室条件下，银蛛在脓疱蜘蛛网上的取食能力显著优于在希蛛网上的取食能力，和Badumna longinquus（L . Koch）。可能是负责托管的偏好和不同类型的网站上的效率变化的因素进行了讨论。
ABSTRAC T The spider Argyrodes antipodiana (O .P. Cambridge) from New Zealand is a kleptoparasite whos e primary host in nature is an orb weaving spider, Aranea pustulosa (Walckenaer) . The kleptoparasite' s bias towards this host is stronger in the summer than in the winter . In the laboratory, Argyrodes wa s significantly better at obtaining food on the webs of Aranea pustulosa, than on the webs o f Achaearanea sp ., and Badumna longinquus (L . Koch) . Factors that may be responsible for hos t preferences and for variation in efficiency on different types of webs are discussed .
