Mayflies are insects which belong to the Order Ephemeroptera (from the Greek ephemeros = ephemeral, or short-lived; pteron = wing). The name refers to the most distinctive features of the adults. They are in an ancient group of insects, the Palaeoptera, ('Ancient wings') with dragonflies and damselflies.

At mating the female lays her eggs in the water where they settle to the bottom and stick to rocks, vegetation or the bottom of the stream. The larvae (called naiads or nymphs) live from several months up to a year, in freshwater. The naiads go through 20 or 30 moults as they develop.

The Common, or 'Green Drake', Mayfly is one of 51 species of mayfly in the UK, and is on the wing from April until September (nymphs are present all year-round). Mayflies are common around freshwater wetlands, from fast-flowing rivers to still lakes, where the larvae spend their lives underwater, feeding on algae and plants. In the summer, the adults hatch out - sometimes simultaneously and in their hundreds; they have very short lives (just hours in some cases), during which they display and breed. Many species do not feed as adults as their sole purpose is to reproduce, dying once they have mated. The name 'mayfly' is misleading as many mayflies can be seen all year-round, although one species does emerge in sync with the blooming of Hawthorn (or 'Mayflower').
