六脚類の節足動物の分類群

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.

注意：本页面含有Unihan扩展A区用字：「䖵、䗛」。有关字符可能會错误显示，詳见Unicode扩展汉字。昆虫在分类学上属于昆虫纲（学名：Insecta），是世界上最繁盛的动物，已发现超過100万种。其中單鞘翅目（Coleoptera）中所含的種數就比其它所有動物界中的種數還多。昆字原作䖵。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。昆虫的身體會分為頭、胸、腹三節，有六隻腿，複眼及一對觸角。昆虫有脂肪體，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。昆虫對生態扮演着很非常重要的角色。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。昆蟲是蜥蜴、青蛙、小型鳥類的重要食物來源。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及人類出現敏感症狀甚至致命。

昆虫（こんちゅう、insect）は、六脚亜門の昆虫綱（学名: Insecta）に分類される節足動物の総称である。昆虫類とも総称されるが、これを昆虫と内顎類を含んだ六脚類の意味で使うこともある。なお、かつては全ての六脚類を昆虫に含めていたが、分類体系が見直され、現在は内顎類（内顎綱）の分類群（トビムシ、カマアシムシ、コムシ）が除外される。この項ではこれらにも触れてある。
