Mayflies (also up-winged flies or up-wing flies, or drake-flies in the UK; shadflies or fishflies in Canada) are aquatic insects belonging to the order Ephemeroptera. This order is part of an ancient group of insects termed the Palaeoptera, which also contains dragonflies and damselflies. Over 3,000 species of mayfly are known worldwide, grouped into over 400 genera in 42 families.

蜉蝣目（学名：Phoebe）通称「蜉蝣」，又名螶𧎾，具有古老而特殊的體型結構，是最原始的有翅昆虫。和蜻蛉目同分为古翅下纲下，他们的翅不能折叠。全世界已知有超过3,000种蜉蝣目昆虫，分属于42个科的400多个属。其中约600种见于北美大陆。除南极外，蜉蝣类昆虫见于所有陆地地区。 蜉蝣目昆虫是相对原始的昆虫，并且表现出可能存在于第一种飞行昆虫中的许多祖先性状，例如不能平折在腹部上的长尾巴和翅膀。虽然化石记录不完全，但有证据表明：泥盆纪(2.8亿年前至3.25亿年前)已有蜉蝣存在。成虫体长2.5～32毫米。生活史包括4个阶段：卵、稚虫、亚成虫和成虫。稚虫生活于淡水中，偶见于咸淡水中，具6足，足端具爪，身体由10个体节组成，其中一些体节具鳃；身体末端具2～3条纤细的尾。不同种的稚虫具不同的适应性构造，有的具适于挖掘的顎及附肢，有的种身体扁平，能在狭窄的空间移动，或适于附在水生生物上。

Mayflies (also up-winged flies or up-wing flies, or drake-flies in the UK; shadflies or fishflies in Canada) are aquatic insects belonging to the order Ephemeroptera. This order is part of an ancient group of insects termed the Palaeoptera, which also contains dragonflies and damselflies. Over 3,000 species of mayfly are known worldwide, grouped into over 400 genera in 42 families.

Mayflies have ancestral traits that were probably present in the first flying insects, such as long tails and wings that do not fold flat over the abdomen. Their immature stages are aquatic fresh water forms (called "naiads" or "nymphs"), whose presence indicates a clean, unpolluted and highly oxygenated aquatic environment. They are unique among insect orders in having a fully winged terrestrial preadult stage, the subimago, which moults into a sexually mature adult, the imago.
