Findings of this study can potentially strengthen our current understanding of the function of body coloration of spiders, shed light on evolution of spider body coloration, and provide new perspectives on symbiotic relationships between animals.īlamires SJ, Lai CH, Cheng RC, Liao CP, Shen PS, Tso IM (2012) Body spot coloration of a nocturnal sit-and-wait predator visually lures prey. We showed for the first time that the orange-red body coloration shared by male Nephila pilipes and kleptoparasitic Argyrodes miniaceus spiders inhabiting webs of female N. However, whether the conspicuous body coloration of mate-seeking males plays any role remains untested. It has been known that the body coloration of some spiders can lure prey to their webs, and even some kleptoparasitic Argyrodes spiders can lure prey to their hosts’ webs. These results indicate that the conspicuously colored web coinhabitants may potentially bring foraging benefits to the hosts through prey luring and provide new perspectives on the ecology and evolution of symbiotic relationships between animals. miniaceus had a significantly higher prey attraction rate than those with body color altered coinhabitants. pilipes webs with naturally colored male N. Our results showed that, in both diurnal and nocturnal conditions, female N. These two types of spiders have similar orange-red body coloration, leading us to investigate the function of this shared trait by manipulating their body color and recording the response of prey insects in the field using video cameras. The golden orb-web spider Nephila pilipes spins giant orb webs and also attracts web coinhabitants such as mate-seeking males and kleptoparasitic spider Argyrodes miniaceus. However, certain species of kleptoparasitic Argyrodes spiders usually reside in the webs of Cyrtophora spiders, and their brightly colored bodies have been demonstrated to serve as a visual lure that attracts prey to host webs. Visual prey luring in animals is typically achieved by brightly colored body parts or excretions of the signal sender, and using signals from other organisms is rarely reported.
