Mayflies are unique among insects in that they moult one more time after acquiring functional wings; this is also known as the alate stage. This last-but-one winged instar usually lives a very short time, often a matter of hours, and is known as a subimago or, to fly fishermen, as a dun. Mayflies in this stage are a favorite food of many fish, and many fishing flies are modeled to resemble them. The adult mayflies are short-lived, from a few minutes to a few days depending on the species. About 2,500 species of mayflies are known worldwide, including about 630 species in North America.
