社会蜘蛛被认为主要通过振动线索来接收有关环境的信息。因此，群体生活带来了一个挑战，那就是如何将有用的振动信息与同伴的背景噪音区分开来。在这里，我们调查是否殖民地的队友之间的空间接近可能允许社会蜘蛛（Stegodyphus dumicola），以减少背景噪音，可能会阻碍振动信息从猎物。为此，我们构建了实验群体，并测量了在休息时彼此接近的蜘蛛数量是否可以预测参与猎物捕获的蜘蛛数量。此外，我们将蜘蛛群落暴露于五种不同的模拟猎物的振动线索，以确定蜘蛛对哪种线索类型最敏感。我们发现，在觅食试验前，聚集在一起的蜘蛛数量与参与集体觅食的蜘蛛数量呈正相关。此外，殖民地更快地回应脉冲振动线索比其他类型的振动模式。这些数据共同揭示了社会互动和猎物线索塑造了社会性坐等捕食者如何体验和应对环境。
Social spiders are thought to predominantly receive information about their environment through vibrational cues. Thus, group living introduces the challenge of distinguishing useful vibrational information from the background noise of nestmates. Here we investigate whether spatial proximity between colony-mates may allow social spiders (Stegodyphus dumicola) to reduce background noise that might obstruct vibrational information from prey. To do so, we constructed experimental colonies and measured whether the number of spiders in proximity to one another whilst resting could predict the number of spiders that participated in prey capture. Additionally, we exposed spider colonies to five different simulated vibrational cues mimicking prey to determine which cue types spiders were most responsive to. We found that the number of spiders huddled together prior to foraging trials was positively correlated with the number of spiders participating in collective foraging. Furthermore, colonies responded more quickly to pulsed vibrational cues over other types of vibrational patterns. Together these data reveal that both social interactions and prey cues shape how social sit-and-wait predators experience and respond to their environment.
