OverviewAI-generated

Insecta is a taxon classified as a subclass and class within the parent taxon Hexapoda. It is an accepted class of arthropods, commonly known as insects, with the scientific name Insecta. The group is studied by entomology and is characterized by insect biodiversity. Members of this taxon reproduce through sexual reproduction and oviparity. The group has existed since about 400 million years ago.

Insects inhabit marine, brackish, and freshwater environments. They serve as a source of food, a practice known as entomophagy, and are used in insect farming. Specific species include the Northern Walkingstick, which is not extinct. The taxon is referenced by 214,765 other encyclopedia articles and appears in various encyclopedic sources such as the Encyclopædia Britannica 11th edition.

昆虫是節肢動物門昆虫纲（学名：Insecta）物種的總稱，為世界上最繁盛的动物類群，据估算全球约有550万种，已发现超過100万個物種。其中單鞘翅目（Coleoptera）中所含的物種數量便佔全動物界所有物種之25%。昆字原作䖵，為眾多之意，故「昆蟲」的原義實為「各種蟲」。目前普遍采用的狭义昆虫的定义是指包括石蛃目、衣鱼目、有翅类昆虫（包括翅退化的种类）在内的一个集合，称为外颚类（Ectognatha）；即昆虫纲与外颚类为同义词。原本昆虫的定义涵盖无翅亚纲及有翅亚纲，但由于现今系统发生学研究显示无翅亚纲并非单系群，所以它不应为一分类群（taxon）；现今，昆虫的定义已不含弹尾目、原尾目、双尾目这三个无翅的节肢动物类群，它们属于内口纲（Entognatha），又稱内颚类。幾乎所有的昆蟲都是從卵中孵化出來，且其生長受到非彈性外骨骼的限制，其發育涉及一系列蛻皮。未成熟期通常在結構、習性和棲息地方面與成蟲不同，且在經歷四階變態（有翅昆虫内生翅类）的群體中，會有相對不活動的蛹期。经历三阶变态（有翅昆虫外生翅类）的群体，则缺乏蛹期，成虫通过一系列若虫（或稚虫）期发育。昆蟲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（Chitin）构成的壳。这层壳会分节以利于运动，犹如骑士的甲胄。昆蟲成體（成蟲）的身體分為頭、胸、腹三節，有六條腿且必定長在胸節處，頭節具一對複眼、一對觸角及一組口器。昆蟲有脂肪體，成分類似脊椎動物的脂肪組織，但作用不同，主要為代謝功能，類似脊椎動物的肝。昆蟲在生態扮演着很重要的角色。虫媒花需要得到昆蟲的帮助，才能传播花粉。许多昆虫被认为是对生态有益的捕食者，少数昆虫提供直接的经济利益。蚕产丝，蜜蜂产蜂蜜，两者都已被人类驯化。昆蟲是蜥蜴、青蛙、中小型鳥類等的重要食物來源。在东南亚和南美的一些地方，昆虫本身就是当地人的食品。但昆虫也可能對人類產生威脅，如蝗虫會破壞農作物，白蟻破壞木材及建築物。而有一些昆虫，例如蚊子，还是疾病的传播者。有一些昆蟲能夠藉由毒液或是叮咬會對人類造成傷害，例如虎頭蜂（一般蜜蜂）在有人入侵地盤時會以螫針注入毒液等。紅火蟻會分泌有毒物質使接觸動物和人類出現症狀甚至致命。
