Outline of Final Research Achievements

Dorsal abdomen of an orb-web spider, Cyclosa argenteoalba, consists of black and silver colorings. The ratio of black area to dorsal abdominal area ranges 20-100% among spiders. Field observation revealed that, while silvery spiders dominated in spring, darker spider increased in summer. In autumn, silvery spiders dominated again. Web location of darker spiders were restricted in shady habitat in summer, possibly to avoid heating. Nevertheless, darker spiders exhibited higher foraging efficiency than silvery spiders. Body color seemed heritable trait. We did not find any relationship between the spider body color and predation rate or web relocation rate. The ratio of abdomen width to abdomen length, a kind of fitness index, was the highest at individuals exhibiting the intermediate rate of the ratio of black area. These indicate that seasonal change in advantageous body color is the reason to maintain body color variation, although more research is necessary for strong conclusions.
