Anelosimus eximius 是南美洲的一种社会性蜘蛛。许多个体共享同一个网并参与捕获猎物，大约需要十秒钟才能在丝状结构中找到猎物。在实验室里，我们分析了参与追逐的每只蜘蛛的动作，结果表明它们都是同步的、有节奏的。蜘蛛交替同时进行静止期（涉及 100% 的攻击个体）和活动期（涉及至少 70% 的蜘蛛）。参考 Goss 和 Deneubourg (1988) 开发的模型对结果进行了讨论，表明自催化可能是社会节肢动物中某些同步和有节奏的活动的动力。
Anelosimus eximius is a social spider species of South America. Many individuals share the same web and participate in prey capture, taking some ten seconds to locate the prey in the silky structures. In the laboratory, we analyzed the movements of each spider which took part in the pursuit, and showed that they were both synchronized and rhythmical. Spiders alternate simultaneous periods of immobility (involving 100% of the attacking individuals) and activity (involving at least 70% of the spiders).The results are discussed with reference to the model developed by Goss and Deneubourg (1988) suggesting that autocatalysis may be the motor of certain synchronized and rhythmical activities in social arthropods.
