Mayflies Diet, Behavior, Reproduction, and Habits
Mayflies are also referred to as lake flies and shadflies. In addition to water, mayflies are attracted to light. Individuals who gather at night close to doorways of businesses and homes find these insects to be a nuisance. In some cases, mayflies gather in substantial numbers. Mayflies are from the insect order Ephemeroptera.

The lifespan of an adult mayfly is short. After mating, male mayflies die. Once the female lays their eggs, they die off as well. Mayflies shed their skin and their body dry out and easily crumbles.

Female mayflies lay their eggs in water. Clean, fresh water is preferred. When mayfly eggs are hatched, the nymphs (immature insects) live close to the bottom. Organic material is a nymph’s food source. Other insects and fish eat these immature insects. Nymphs leave the water once they mature. The next day or two is spent drying and shedding their skin. These mayflies then continue the cycle of mating and laying eggs.

If possible, attract mayflies away from commercial buildings or homes by utilizing insect light traps containing a UV light.
