Life Cycle Mating occurs during flight and large swarms of mayflies gather close to the fresh water habitats they prefer. Mayfly larvae do not survive in polluted aquatic habitats and, thus, have been chosen as bioindicators, markers of water quality in ecological assessments. Mayfly Morphology The first stage of the life of a mayfly is the nymph (larva), which not only looks very different from the adult, but lives in the water. Schmitt added, “Shortly before the transition from aquatic to terrestrial life, a layer of air forms between the old and new skin of the adult larvae. The insect, whose scientific name is Ephemera danica, only has a few days to fly, mate and lay new eggs. Depending on the species of the nymph, the number of instars can range from 12 to 45.

They spend brief lives as flighted insects mating and dropping eggs in water. which attacks eucalypts in south-eastern Australia. Home Insects Mayfly. "What makes the mayfly unique is its life cycle: from the egg laid in the water to the insect capable of flight and mating, which dies after a few days,” said Thomas Schmitt, chairman of the commission of scientists and representatives from research institutions and conservation organizations from Germany, Austria and Switzerland that made the choice. The developmental stages of naiads are known as instars. During this time, they grow and molt over and over — as many as 50 times for some species. After hatching, a mayfly larva feeds, grows and develops, some males building burrows to live in and feed from, while others just cruise around in the aquatic vegetation, finding snacks.

The mayfly larva is a detritus feeder and by stirring the sediment in front of its head with the comb-like claws of the front legs it creates a cloud of only the finest particles suspended in the feeding current. “What makes the mayfly unique is its life cycle: from the egg laid in the water to the insect capable of flight and mating, which dies after a few days,” said Thomas Schmitt, chairman of the commission of scientists and representatives from research institutions and conservation organizations from Germany, Austria and Switzerland that made the choice. Among the aquatic invertebrate predators are stoneflies, caddisflies, alderflies, dragonflies, water beetles, leeches, triclads, and crayfishes. The legs and jaws of some nymphs are modified for burrowing in silt or sand, whereas in other species, these are flattened to facilitate entering narrow crevices or clinging to bottom materials in swift currents.

The new naiads are very tiny with no gills. Ephemera danica can reach an imago size of 15–20 mm (0.6–0.8 in) in males, while females are larger, reaching 16–25 mm (0.6–1.0 in). Some species will last only for 24 hours in the adulthood (including both Subimago and Imago phases). The larva is often used as a bioindicator species to measure the health of water. Mayfly larvae (also called naiads or nymphs) are slender and soft-bodied, like adults, though they lack wings, have a series of leaflike or feathery external gills attached along the sides or on the top rear portion of the abdomen, have smaller eyes than adults, and often have a flattened head that helps them to adhere to rocks in fast-flowing water.

When the nymphs hatch from the eggs, they are less than 1 mm long. Birds and winged insects, such as Odonata, also prey on mayfly adults. Mayfly larvae are long-lived compared to mature species, which have a life-span of just several days. As an adult, I cannot eat because I do not have a functional mouth. Mayfly Facts: 16-20 | Reproduction in Mayflies . The first two take place in the water as an egg and then a larva. Their life cycle includes four stages – egg, nymph, subimago and adult (imago).
