Female mayflies lay 500 to 1000 eggs each, dropping them into or placing them under the water’s surface. Immature mayflies (naiads) are aquatic, living under water, especially running water, for 6 weeks to 3 years, and going through 21 molts as a naiad. They are eaten by birds, bats, dragonflies, toads, frogs and fish. Adults do not have functional mouth parts and do not eat; they only live for a few hours./field-station/wp-content/uploads/sites/380/2017/02/mayfly-1.jpg
