Some spiders were easily observed on the campus of Nagasaki University from autumn to winter such as Argiope bruennichi, Thomisus labefactus, Cyclosa confuse, Hasarius adansoni, Argyrodes bonadea, and Leucauge blanda. The spiders that could be found in the field even in winter, outside of the period in which adults are expected to appear by literature, had white, silver, and golden parts of the body surface. The case that the crab spider T. labefactus preyed A. bruennichi in its center of the web is considered to be unique. UV-vis spectrum of L. blanda was measured and shown that the body had gold and yellow parts.
