Mayflies are aquatic insects belonging to the order Ephemeroptera. They are known for their short adult lifespan, which can range from a few hours to a few days. Mayflies undergo a unique life cycle that includes several nymph stages spent in water, where they feed on organic matter. Once they emerge as adults, they primarily focus on reproduction. These insects are often found near freshwater bodies like rivers and lakes. Mayflies are important indicators of water quality, as their presence suggests a healthy ecosystem. Their swarming behavior during mating season can create spectacular displays, attracting both predators and nature enthusiasts alike.
