利用400 ~ 700nm波长范围内的光反射率对不同季节蜘蛛丝的光学特性进行了研究。研究发现，同一地区雌蛛的蛛丝颜色随季节变化，从夏季的白色或半透明到秋季的黄色，这种颜色的变化可归因于成熟雌蛛的蛛丝，在保护蜘蛛免受捕食者的侵害和捕获猎物方面具有重要作用。
The optical properties of spiders' threads in different seasons were studied by optical reflectance in the range of wavelength from 400 to 700nm. It was found that the color of threads from female spiders Nephila clavata collected in the same area changed seasonally from white or semitransparent in summer to yellow in autumn according to the seasonal change in the environment This change in color was concluded to be ascribed to the seretions from the mature female spiders Nephila clavata and to play an important role not only in protecting spiders from predators but also in capturing preys.
