资源描述

1益虫自白杜鹃:我叫杜鹃,因为叫声有点像“布谷” ,又正好播种季节到来,人们也称我为“布谷鸟” 。我的主要食物是各种毛虫,一小时就能吃掉 5 万多条害虫,为保护农作物尽了自己的一份力量。喜鹊:我叫喜鹊,每天清晨和伙伴们一起飞到田野里、草地上追逐害虫,像蝗虫、松毛虫和夜蛾等害虫都逃不过我的眼睛,所以人们称我为“田野卫士” ,在民间还流传着“喜鹊叫,喜事到”的说法,对我十分欢迎。猫头鹰:我叫猫头鹰。以前有些人说看见我是不吉利的,这真是天大的冤枉。我能够捕捉和吃掉田里的野鼠。这些野鼠可坏啦,专门糟蹋粮食,我只要一看见它们,就马上冲过去把它逮住,即使我已经吃饱了,也要把它杀死,决不让它再害粮食。一个夏天,我能消灭 1000 只田鼠,等于为人类夺回一吨粮食。蜻蜓:我叫蜻蜓,我是昆虫中出色的“飞行家” ,可以连续飞行一小时不着陆。在水面上飞行时,雌蜻蜓常用尾巴点水,这是它将卵产在水里。我最爱吃蛾子、苍蝇、蚊子等害虫,是人类的好朋友。
