What is the lifespan of a mayfly?

The lifespan of a mayfly varies depending on the species and the environment. Most mayflies have a very short lifespan, with some species living for only a few hours or days. This is because mayflies undergo a rapid metamorphosis, changing from an aquatic larva to a terrestrial adult in a short period of time. Once they reach the adult stage, mayflies typically mate and lay eggs before dying. The lifespan of adult mayflies can range from a few hours to a few weeks, depending on the species and environmental conditions. Mayflies are important members of many aquatic ecosystems, and their short lifespans play a role in the dynamics of these ecosystems.
