在形形色色的昆虫世界里,蝉还是一个寿星老儿呢。有的小朋友可能会说,不对呀,每年到不了中秋节,蝉的叫声就听不到了,也看不到它们的踪影了,怎么能算是寿星老儿呢? 其实,每年夏天,躲在树枝上,“知了——知了——”地唱歌的是雄蝉。天气越热,雄蝉唱得越欢。它唱歌是为了寻找雌蝉,而雌蝉是不会唱歌的。因此,人们常说,蝉的妻子是个哑巴。雄蝉和雌蝉结婚后,雌蝉在树枝里面产卵。卵在树枝里孵化成幼虫便掉到地上,钻进泥土里开始它漫长的隐居生活。蝉的幼虫在地下隐居几年甚至十几年后,才从土里钻出来,脱掉淡黄色的衣服,变成有翅膀的蝉。雄蝉爬到树枝上再唱起知了——知了——那响亮的歌。你们说,蝉是不是昆虫世界的老寿星呢? In all kinds of insects in the world, cicada or a longevity child it. Some children may say, no, every year can not reach the Mid-Autumn Festival, cicadas can not hear the call, they can not see their traces, how can be regarded as longevity Lao Er? In fact, every summer, hiding in the branches On, “Know - Knows - ” to sing is the male cicadas. The hotter the weather, the more lively the male sing. It sings for the female cicada, and the female cicada does not sing. Therefore, people often say that the cicadas wife is a dumb. After the male and female cicadas are married, the female cicada spawns in the branches. The eggs hatch into larvae in the branches and fall to the ground, drilling into the earth to begin its long seclusion. Cicadas larvae secluded in the ground for a few years or even ten years later, before drilling out from the soil, take off the yellow clothes, into a winged cicada. The cicada climbs onto the branch and sings again - knowing - the loud song. You say that cicadas are not the old longevity of the insect world?
