Proceedings of the Royal Society B: Biological Sciences 268 (1476) : 1553-1558. ScholarBank@NUS Repository. https://doi.org/10.1098/rspb.2001.1709 | Abstract: | Conspicuous behaviour exposes animals to predation; prey-attraction thus often conflicts with antipredator behaviour. The fact that a conspicuous ultraviolet-light reflecting silken structure in the orb-webs of certain spider species, known as a stabilimentum, makes the webs obvious to both prey and predators has been used to argue that spiders benefit from building stabilimenta by attracting prey and/or defending against visually hunting predators. Here, we provide experimental evidence that stabilimenta can act as visual signals that attract web-invading spider-eating predators with acute vision to the webs. We also show that the predators can learn to remember a particular type of stabilimentum. Thus, stabilimentum-building spiders risk a high level of predation by attracting visually hunting predators. | Source Title: | Proceedings of the Royal Society B: Biological Sciences | URI: | http://scholarbank.nus.edu.sg/handle/10635/101717 | ISSN: | 09628452 | DOI: | 10.1098/rspb.2001.1709 |
