female mayflies usually live up to five minutes after larvae stage while males can live up tp two days.
mayflies live most of their lives underwater.
mayflies have been around for more than 300 million years.
At the end of the mayfly life cycle, after mating, the females fall to the water and lay their eggs. Then both male and female mayfly act as food for hungry fish and birds.

life cycle

Mayflies have an incomplete metamorphosis but it is a bit of a unique version of hemimetabolism.The life cycle of mayflies consists of four stages: egg, nymph, subimago, and imago.

egg stage: They begin as a fertilized egg laid by female mayflies in the water, which develops into a nymph or more technically a naiad. mayfly eggs could take ten days to several months to hatch.

Nymph stage: Nymphs go through a number of molts (ecdysis) as they grow and get larger.Nymphs are generally broken into four categories based on where and how they live and feed as nymphs - swimmers, clingers, crawlers, and burrowers.

adulthood: In transitioning to adulthood, nymphs emerge to become "duns" basically a "pre-adult" stage. This happens in different places and different rates of speed for different species. Mayflies then undergo one more metamorphosis to become imagos or spinners.

Winged mayflies have large compound eyes, short, bristlelike antennae, and functionless mouthparts and digestive tracts.

Once mayflies enter the winged stages they cannot feed. Their membranous wings include a large, triangular front pair and a much smaller, rounded hind pair.the wings are held together upright over the body like those of a butterfly.

Nymphal characters include a single claw terminating each of the six legs.

The abdominal region is usually long and slender. Gills are attached to the outer edge of the upper surface of some of the ten segments into which the body is divided.

Food source
Mayflies are a key food source for many animals, including fish, birds, bats, and other invertebrates. Mayfly nymphs are eaten by fish like trout, while mayfly eggs are eaten by caddisfly larvae and snails.
Indicator of water health
Mayflies are sensitive to pollution and are often found in high-quality, minimally polluted bodies of water. They are one of the most common indicators of aquatic ecosystem health.
Habitat
Mayflies provide habitat for other organisms.
Environmental degradation
Mayflies are threatened by pollution, invasive species, habitat loss, and climate change. Some species of mayflies in North America are already extinct, and others are endangered.
Mating
Mayflies mate in midair, with the female laying thousands of eggs in the water after mating.
Lifespan
Adult mayflies, also known as spinners, have no mouth parts and cannot eat, so they usually only live for a single day.
