There are about 900,000 known insect species,three times as many as all other animal species together,and thousands of new ones are described each year.They are commonly grouped in 27 to 32 orders,depending upon the classification used.The largest order is that of the beetles (Coleoptera).Next,in order of size,are the moths and butterflies (Lepidoptera); the wasps,ants,and bees (Hymenoptera); and the flies and mosquitoes (Diptera).Other major orders are the true bugs (Hemiptera); the cicadas,aphids,and scale insects (Homoptera); the grasshoppers and crickets (Orthoptera); the cockroaches (Blattodea); and the mantids (Mantodea).

我最喜歡的昆蟲(chóng)
我最喜歡的昆蟲(chóng)是知了.知了有兩個(gè)名字,又叫知了又叫蟬.知了是夏天常見(jiàn)的小動(dòng)物,它有六只腳,前腳是彎彎的大刀,可以當(dāng)作它的武器,它的每一只腳上有一個(gè)勾子.知了的翅膀像有裂縫的玻璃.知了小時(shí)候是在地下的,長(zhǎng)大的時(shí)候才鉆出來(lái),聽(tīng)說(shuō)它的殼還能做藥呢!知了的食物是樹(shù)枝里的汁,只要嘴巴上的那根管插上去,就能痛痛快地吸汁了.知了爸爸的肚子下面有一個(gè)能叫的“馬達(dá)”,只要一摁就可以叫起來(lái),它的聲音很響亮,三十米外都能聽(tīng)得很清楚.
我常常和小朋友去抓知了,我們來(lái)到大樹(shù)底下,看見(jiàn)樹(shù)上有很多知了.有一次,刮風(fēng)的時(shí)候有一只知了飛下來(lái),被我抓住了.我把它放進(jìn)一個(gè)大瓶蓋里,然后放進(jìn)裝滿水的盆里,它就爬到水里去了.我心里想：可能它想喝水吧.沒(méi)想到它是下去游泳的,它還會(huì)潛水呢!它在水里拍拍小翅膀,再潛到水里,它在水里叫,水里冒出很多泡泡.我把它從水里拿出來(lái),它就不叫了.當(dāng)我把它放在地上,它像陀螺一樣的轉(zhuǎn)動(dòng),翅膀張開(kāi)了,就快樂(lè)地唱起歌來(lái).

Lepidoptera Life Cycles
The life cycle of Lepidoptera (butterflies, skippers, and moths) consists of four distinct stages: egg, larva (caterpillar), pupa (chrysalis or cocoon) and adult.
The butterfly, skipper or moth begins life as a tiny egg. Females lay their eggs on specific plants (called host plants or food plants) that serve as food for the next stage, the caterpillar.
Within several days, a caterpillar (or larva) chews its way out of the egg. Caterpillars spend their life eating - increasing their weight more thasn 3000 times. As it grows, the caterpillar molts, or sheds its exoskeleton, 4-5 times.
After several weeks the caterpillar prepares to enter the pupal stage. The butterflies attach themselves to a firm support, shed their exoskeleton and become a chrysalis. Moth and skipper caterpillars cover themselves with silk (forming a protective cocoon), shed their exoskeleton and pupate. The chrysalis stage may last several weeks -- during which time the body of the caterpillar is broken down and slowly reformed into the body of an adult butterfly. The pupae inside the cocoons of moths generally spend the winter in the cocoon before completing their transformation the following spring.
The new adult emerges from the chrysalis or cocoon with soft, wrinkled wings. Fluid and blood from ther bosy are pumped intot he wings., inflating them to their full size. After the wings inflate and harden (a process that generally takes several hours) the adult butterfly or moth is able to fly and begin its search for food and/or a mate.
