a short-lived, slender insect (order Ephemeroptera) with delicate, transparent wings and two or three long filaments on the tail. It lives close to water, where the chiefly herbivorous aquatic larvae develop.
Soft-bodied insect found worldwide. The adult does not eat and lives only a few days, but the aquatic larvae (nymph
) may live several years. Adults have triangular front wings, characteristic thread-like tails, and vestigial mouthparts; they often emerge from streams and rivers in swarms. Length: 10–25mm (0.4–lin). Order Ephemeroptera.
this short-lived insect is proverbial for its brief existence.
