insects, related to dragonflies and damselflies. They are relatively
primitive, with 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 (nymphs) live in fresh water. Unique
among insect orders, they have a fully winged adult stage that moults
into a sexually mature adult. Often, all the mayflies in a population
mature at the same time, emerging in the spring, summer or autumn in
enormous numbers; some hatchings attract tourists. Mayflies are a
favourite food of many fish, and fishing flies are often modelled to
resemble them. The brief lives of mayfly adults—less than five minutes
for the female Dolania americana, after the final moult—have been
noted by naturalists and encyclopaedists since Aristotle and Pliny the
Elder. The English poet George Crabbe compared a daily newspaper's
lifespan to that of a mayfly in the satirical poem "The Newspaper"
(1785).

Wikiquote quote of the day:
Like integrity, love of life was not a subject to be studied, it
was a contagion to be caught. And you had to catch it from someone who
had it.
