“南阳诸葛亮,稳坐中军帐。排下八卦阵,单捉飞来将。”这则谜语告诉我们:蜘蛛专吃活的飞虫。难道它不吃死的东西吗?这引起了我的兴趣,我就做了个实验加以证明。先准备实验材料:一只小蜘蛛、一个塑料筐、一只死苍蝇和一只活苍蝇。我把小蜘蛛放进塑料筐里,耐心等它结网后,就用镊子把死苍蝇放上去。由于蛛网震动,蜘蛛马上爬了过来。可蛛网很快停止震动了,蜘蛛也停下了脚步,然后朝死苍蝇的相反方向爬去。 “Nanyang Zhuge Liang, sit firmly in the military account .A row Bagua Zhen, a single catcher will. ” This riddle tells us: spider eat live insects. Could it not eat anything dead? This aroused my interest, I did an experiment to prove it. First prepare the experimental material: a small spider, a plastic basket, a dead fly and a live flies. I put the little spider in a plastic basket and, after waiting patiently for it to mesh, put the dead fly on with tweezers. As the spider web vibrates, the spider crawls right away. Spider webs stopped shaking soon, spiders stopped and crawled in the opposite direction of dead flies.
