“好虫”不长命

Whom the gods love die young， it is the same with insects.When is your last time to see a ladybug or a firefly? Now coming across these lovely little creatures has become something unusual. And the possible occasion for us to see many a butterfly at a time is on a wedding.Why?

Because there are fewer and fewer these so called“good insects”—— lovely tiny flying dancers that do not trouble people and can even add beauty to the natural environment.

While it seems that“bad”insects like mosquitoes，ticks and cockroaches that can harm the environment or humans（Many are known to bite or sting， others carry dangerous diseases.）see the increase of their population and stay healthy.

Scientists say there is growing evidence that these helpful insects are reducing across the world.

Many of these insects are very important to plant growth and development.They also play a big part in the food chain and can help break down dead animal bodies.

A continual drop in the number of helpful insects could result in a total breakdown of the ecosystem.

好人不长命，昆虫亦然。你上次见到瓢虫或者萤火虫是什么时候？现在，与这些可爱的小生灵相遇变成了一种奢侈。而最有可能一次见到好多蝴蝶的场合是在婚礼上。为什么会这样？

因为这些所谓的“益虫”的数量一直在减少。这些可爱的会飞的小舞者不仅不烦扰人类，还让我们的自然环境更加美丽。

同时，那些对人类和环境有害的“害虫”，比如蚊子、蜱虫还有蟑螂（它们有的叮咬人，有的携带危险的病菌）的数量没有减少，且活得很健康。

科学家表示不断有证据表明全球范围内的益虫在逐年减少。

这些益虫很多有益于植物的生长，它们是食物链重要的一环，它们还可以分解动物的尸体。

这些益虫数量的持续下降可能引起整个生态系统的破坏。
