Hungry spiders tune up web jiggliness

An Asian spider spins webs of different designs depending on how hungry it is, reports a Japanese researcher.

A well-fed Octonoba sybotides spider adds silk bands along web spokes, Takeshi Watanabe of the University of Kyoto has observed. When the spider gets hungry, however, it arranges the bands so that they spiral toward the web’s hub.

The two web types respond differently to incoming prey, Watanabe argues in the March 22 Proceedings of the Royal Society of London B.
