昆虫种类繁多、形态各异，属于无脊椎动物中的节肢动物，是地球上数量最多的动物群体，在所有生物种类（包括细菌、真菌、病毒）中占了超过50%，它们的踪迹几乎遍布世界的每一个角落。
直到21世纪初，人类已知的昆虫有100余万种，但仍有许多种类尚待发现。昆虫在动物界中种类最多，数量最大，对农业生产和人类健康造成重大影响。最常见的有蝗虫、蝴蝶、蜜蜂、蜻蜓、苍蝇、草蜢、蟑螂等。
昆虫不但种类多，而且同种的个体数量也十分惊人。昆虫的分布面之广，没有其他纲的动物可以与之相比，几乎遍及整个地球。分有不同的种类。多数昆虫可以做标本，是人类可以利用的良好生物资源。
昆虫的身体分为头、胸、腹三部分。成虫通常有2对翅和6条腿，翅和足都位于胸部，身体由一系列体节构成，进一步集合成3个体段（头、胸和腹）。一对触角头上生，骨骼包在体外部；一生形态多变化，遍布全球旺家族。是节肢动物中种类最多的一种。
昆虫是世界上最繁盛的动物，已发现100多万种，比所有其他动物种类加起来都多。
昆虫的构造有异于脊椎动物，它们的身体并没有内骨骼的支持，外裹一层由几丁质（英文 Chitin）构成的壳。这层壳会分节以利于运动，犹如骑士的甲胄。
昆虫在生物圈中扮演着很重要的角色。虫媒花需要得到昆虫的帮助，才能传播花粉。而蜜蜂采集的蜂蜜，也是人们喜欢的食品之一。在非洲、东南亚和南美的一些地方，昆虫本身就是当地人的食品。
但昆虫也可能对人类产生威胁，如蝗虫和白蚁。而有一些昆虫，例如蚊子，还是疾病的传播者。
有一些昆虫能够借由毒液或是叮咬对人类造成伤害。例如胡蜂会以螫针向入侵者注入毒液。
There are many kinds of insects with different shapes. They belong to arthropods among invertebrates. They are the most numerous animal group on earth. They account for more than 50% of all biological species (including bacteria, fungi, viruses), and their traces are almost everywhere. Every corner of the world.
Until the beginning of the 21st century, there were more than 1 million species of insects known to mankind, but there are still many species yet to be discovered. Insects are the most species and number in the animal kingdom, and they have a major impact on agricultural production and human health. The most common ones are locusts, butterflies, bees, dragonflies, flies, grasshoppers, and cockroaches.
Not only are there many types of insects, but the number of individuals of the same species is also amazing. The distribution of insects is so wide that no other class of animals can compare with it, almost all over the earth. There are different types. Most insects can be used as specimens and are good biological resources that humans can use.
The body of an insect is divided into three parts: head, chest, and abdomen. Adults usually have 2 pairs of wings and 6 legs. Wings and feet are located on the chest. The body is composed of a series of somites, which are further assembled into 3 individual segments (head, chest and abdomen). A pair of tentacles are born on the head, and the bones are wrapped around the outside of the body; there are many changes in the shape of the whole life, all over the world. It is the most diverse species of arthropods.
Insects are the most prosperous animals in the world. More than 1 million species have been discovered, more than all other animal species combined.
The structure of insects is different from that of vertebrates. Their bodies are not supported by endoskeleton and are covered with a shell made of chitin (English Chitin). This shell will be divided into sections to facilitate sports, just like the armor of a knight.
Insects play an important role in the biosphere. Entomophilous flowers need the help of insects to spread pollen. The honey collected by bees is also one of people’s favorite foods. In some parts of Africa, Southeast Asia and South America, insects themselves are food for the locals.
But insects may also pose a threat to humans, such as locusts and termites. Some insects, such as mosquitoes, are also disease carriers.
Some insects can cause harm to humans through venom or bites. For example, wasps inject venom into intruders with stings.
