      蜘蛛報晴雨

      據觀測,在我國許多地方。如見蜘蛛張網,陰雨天氣將會轉晴。如見蜘蛛收網,天氣將轉為陰雨。
          蜘蛛能預測天氣,主要是因蜘蛛對空氣中濕度變化反應相當靈敏,在蜘蛛尾部有許多小吐絲器,吐絲器部分既粘又涼,當陰雨天氣來臨時,由于空氣中濕度大,水汽多,水汽易在蜘蛛吐絲器部分凝結成小水珠,這樣蜘蛛吐絲時感到困難,便停止放絲而收網。相反,當空氣中濕度變小天氣轉好時,蜘蛛吐絲順利,便張網捕蟲了。
          另據研究,蜘蛛的腿能感知20—50赫頻率的聲音,當天氣轉晴時昆蟲易活動,飛行時發出的嗡嗡聲,蜘蛛蛛很快就會發覺,所以便添絲織網,準備捕捉。這正是民間用“蜘蛛掛網,久雨必晴”諺語來觀測天氣晴雨的道理。
