Mayfly largely feed on algae, fungi and decaying plant materials and then digest what they can and pass out waste
All insects live all year round, of course, but the adult forms of the Mayfly only live for one day.

Insect nymphs are immature insects who turn into adults by stages, called instars, in contrast to insects with grub-like larvae who pupate such as mosquitos or butterflies. Aquatically this usually refers to dragonflies, damselflies, mayflies, and stoneflies while grasshoppers are a good example of a terrestrial species with nymphs. All the aforementioned aquatic nymphs mainly breathe through gills, though the location on the body can vary.

Swimming Mayfly Nymphs (also called naiads) fall under the order Ephemeroptera and the family Baetidae or Leptophlebidae.

most types of mayfly nymphs are omnivorous but some types can be either herbivores or carnivores as well
Spiny crawler is what the Hendrickson mayfly (Ephemerella subvaria) nymph is called.Specifically, the nymph is the immature developmental stage of the mayfly. It is what hatches out of the eggs laid by the female after mating with the male Hendrickson mayfly. It looks like a developing, smaller version of the mature Hendrickson mayfly.

Yes, mayfly nymphs can serve as indicators of water quality. They are sensitive to pollution and changes in their environment, so their presence typically signifies good water quality, while their absence or a decline in their population may indicate poor water conditions. Monitoring mayfly populations can thus be useful for assessing ecosystem health.
An immature mayfly, known as a nymph, typically has a long, slender body with a flattened shape, and is often brown or green for camouflage in aquatic environments. They possess several pairs of gills along their abdomen, which aid in respiration, and have a set of three long tails extending from the rear. Mayfly nymphs also have large, compound eyes and can vary in size, usually measuring a few millimeters to several centimeters long, depending on the species.
Mayfly larvae are preyed upon by a variety of animals, including fish species such as trout, bass, and panfish, as well as aquatic insects like dragonfly nymphs and diving beetles. Additionally, some birds and amphibians also feed on mayfly larvae as part of their diet.

There are many species of mayfly, some do not lay eggs, but for the species best known to fly fishermen and commonest in the UK, they lay eggs pretty much the same way as all flies - they are deposited from the rear of the abdomen. They are laid directly into the surface of running water.
