The mayfly (order Ephemeroptera) typically hatches, matures, mates, and dies within the span of a few short hours (though the longest-lived species may survive a record two days); poets sometimes use this insect to symbolize life's ephemeral nature. When "ephemeral" (from the Greek word "ephēmeros," meaning "lasting a day") first appeared in print in English in the late 16th century, it was a scientific term applied to short-term fevers, and later, to organisms (such as insects and flowers) with very short life spans. Soon after that, it acquired an extended sense referring to anything fleeting and short-lived (as in "ephemeral pleasures").
