Anisoptera
Also known as dragonfly suborder, dragonfly, dragon fly, dragonflies, dragon-fly
A dragonfly is a flying insect belonging to the infraorder Anisoptera below the order Odonata. About 3,000 extant species of dragonflies are known. Most are tropical, with fewer species in temperate regions. Loss of wetland habitat threatens dragonfly populations around the world. Adult dragonflies are characterised by a pair of large, multifaceted, compound eyes, two pairs of strong, transparent wings, sometimes with coloured patches, and an elongated body. Many dragonflies have brilliant iridescent or metallic colours produced by structural coloration, making them conspicuous in flight. An a
AI overview
Anisoptera is the scientific group that includes dragonflies, a diverse order of flying insects with about 3,000 known species that are found worldwide, particularly in tropical regions. These insects are notable for their large compound eyes, two pairs of strong wings, and elongated bodies, and they face threats from wetland habitat loss around the world.

蜻蜓是差翅下目（学名：Anisoptera）动物的通称，是一種屬於蜻蛉目的昆蟲，部分種類全年出現，有細長翅膀與腹部。 蜻蜓，又稱灯烃、负劳、蟌、蝍蛉、桑蜋、蜻虰、纱羊、青娘子、尋塘，尾庵，塘梶（广州话）是屬於蜻蛉目差翅亞目的昆蟲。它的特徵包括碩大的複眼，兩對強而有力的透明翅膀，以及修長的腹部，长约8厘米。停止時翅膀為平放。 蜻蜓一般捕食蚊子、搖蚊和其他小昆蟲, 例如蒼蠅、蜜蜂、蝴蝶等，部分甚至捕食魚類。常雌雄成群，在水边飞行，交尾后，雌虫产卵于各種環境中，如水中、水草上、樹枝上。 蜻蜓通常在稚蟲（水蠆）棲息的湖泊、池塘、溪流或濕地附近活動。由於它們獵食害蟲, 故此被視為重要的捕獵者。 《日華子本草》說：“蜻蜓，涼，無毒。”“入药去翅足，炒用良”，《别录》：“强阴止精。”《陆川本草》：“治肾虚陽萎。”為四川名菜。 蜻蜓的祖先最初出現於泥盆紀，大約到了3億年前石炭紀時期大氣含氧量比現在還要高，蜻蜓開始演變得巨大，巨脈蜻蜓翅膀到達75厘米。大約經過5000萬年，從二疊紀中期到晚期，大氣含氧量減少，蜻蜓的身體開始縮小，牠們渡過幾億年甚至逃過大滅絕還生存的昆蟲。

A dragonfly is a flying insect belonging to the infraorder Anisoptera below the order Odonata. About 3,000 extant species of dragonflies are known. Most are tropical, with fewer species in temperate regions. Loss of wetland habitat threatens dragonfly populations around the world. Adult dragonflies are characterised by a pair of large, multifaceted, compound eyes, two pairs of strong, transparent wings, sometimes with coloured patches, and an elongated body. Many dragonflies have brilliant iridescent or metallic colours produced by structural coloration, making them conspicuous in flight. An adult dragonfly's compound eyes have nearly 24,000 ommatidia each.
Dragonflies can be mistaken for the closely related damselflies, which make up the other odonatan infraorder (Zygoptera) and are similar in body plan, though usually lighter in build; however, the wings of most dragonflies are held flat and away from the body, while damselflies hold their wings folded at rest, along or above the abdomen. Dragonflies are agile fliers, while damselflies have a weaker, fluttery flight. Dragonflies make use of motion camouflage when attacking prey or rivals.
