我最喜欢的昆虫
我最喜欢的昆虫是知了.知了有两个名字,又叫知了又叫蝉.知了是夏天常见的小动物,它有六只脚,前脚是弯弯的大刀,可以当作它的武器,它的每一只脚上有一个勾子.知了的翅膀像有裂缝的玻璃.知了小时候是在地下的,长大的时候才钻出来,听说它的壳还能做药呢!知了的食物是树枝里的汁,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个能叫的“马达”,只要一摁就可以叫起来,它的声音很响亮,三十米外都能听得很清楚.
我常常和小朋友去抓知了,我们来到大树底下,看见树上有很多知了.有一次,刮风的时候有一只知了飞下来,被我抓住了.我把它放进一个大瓶盖里,然后放进装满水的盆里,它就爬到水里去了.我心里想：可能它想喝水吧.没想到它是下去游泳的,它还会潜水呢!它在水里拍拍小翅膀,再潜到水里,它在水里叫,水里冒出很多泡泡.我把它从水里拿出来,它就不叫了.当我把它放在地上,它像陀螺一样的转动,翅膀张开了,就快乐地唱起歌来.

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 *** .
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 bee 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 -- ring which time the body of the caterpillar is broken down and slowly reformed into the body of an *** butterfly. The pupae inside the cocoons of moths generally spend the winter in the cocoon before pleting their transformation the following spring.
The new *** 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 *** butterfly or moth is able to fly and begin its search for food and/or a mate.
