	Farm Sanctuary - Shelter and Adoptions
		Mayfly the rooster was part of a school hatching project gone awry.
		Were it not for a kind parent of one of the students, he most likely would have died in a schoolroom having never gotten to frolic in a barnyard, dustbathe or scratch happily in the dirt.
		Shortly after their birth, Mayfly and his brother somehow got wet, and they subsequently became sick because they were left uncared for.

	Gordon's Mayfly (Ephemeroptera) Page
		Mayflies date from the Carboniferous and Permian times and are the oldest of the extant (still living) winged insects, they are unique in being the only insect order to have a subimago (last non-adult life stage) with wings.
		Mayflies have attracted man's attention for a long time and one of the oldest accounts of Mayfly biology was published by Swammerdam in 1675, it is an unfortunate fact that the genus of Mayflies studied by Swammerdam Palingenia sp.
		Mayfly larvae are called nymphs and generally have 3 tails, gills on their abdomen and only one claw on each leg.

	Mayfly
		Some female mayflies will even use a protruding stem, leaf or other organic structure to crawl into the water in order to safely deposit her eggs at the bottom of the water column and others will actually dive into the waters surface in order to break the surface tension, then release the eggs underwater.
		The Mayfly goes through an incomplete metamorphosis, which simply means that the insect misses one of the underwater insect stages common to most other aquatic insects.
		Between the molts and during the instars the nymph is very vulnerable to its principal animal, bird, fish, amphibian and insect predators such as: dragon fly nymphs and adults, diving beetles, frogs, back-swimmers, salamanders, swifts, swallows and phoebes.

	Making the most of Mayfly - Flyfishing the Scottish Highlands
		Scottish mayfly have an odd and ultimately sad lifecycle first spending up to two years as a nondescript burrowing grub in the marl margins of Caithness lochs before slowly emerging to the surface as a semi transparent brownish colored nymph.
		Once the mayfly (known as dun at this stage) are on the water you will see the familiar flotilla of three tailed upright winged insects adrift and big trout cruising around busily snapping them up.
		Those mayfly which do escape the fish, take to the air and scutter off the water to attach themselves to heather or trees there to dry their wings for a period of about two days.

	Mayfly - MSN Encarta
		Mayflies usually spend one to three years as underwater nymphs, breathing by means of gills and feeding on microscopic plant life.
		(Mayflies are the only insects to molt in a winged stage.) Now fully adult, they cannot feed, but instead they form male and female swarms that mate over water.
		Mayflies are among the oldest insect groups and have been found as fossils dating from about 300 million years ago.

	mayfly. The Columbia Encyclopedia, Sixth Edition. 2001-05
		Mayflies, also called June bugs, shad flies, and salmon flies, emerge by the thousands from streams, ponds, and lakes at twilight in the early spring; the males form large mating swarms and when a female flies into the swarm she is seized by a male and the two depart to mate.
		The insect undergoes incomplete metamorphosis, the egg hatching directly into an aquatic naiad, or nymph, with chewing mouthparts, which passes through some 20 nymphal stages over a period of two years or more, feeding on algae and diatoms and breathing oxygen taken directly from water by gills.
		Mayflies are classified in the phylum Arthropoda, class Insecta, order Ephemeroptera.

	Ephemeroptera
		Once a mayfly completes development as a naiad, it leaves the aquatic environment, often rising to the water surface in a bubble of air.
		In some mayfly species, summer emergence of winged stages is a sudden and dramatic event that occurs almost simultaneously throughout the entire population.
		Mayflies are a favorite bait of fishermen, and many popular fishing "flies" are tied to resemble mayflies.

	Adidas 1, Nike Mayfly (Site not responding. Last check: )
		Nike's Mayfly was inspired by the ideal set forth by Nike founder Bill Bowerman, who envisioned a shoe that would provide enough support for a runner during a race, but would fall apart once that runner crossed the finish line.
		The 62-mile recommended lifespan of the Mayfly, which is named after the insect whose adult life span can last as short as five minutes, is mostly meant for a runner who plans to use it for a summer full of 5 kilometer (3.1 miles) races.
		That also means that there won't be many Mayfly purchasers returning the shoes when they are done with the big race, despite Nike's pledge to be environmentally conscious and the free postage attached.

	Mayfly Genus Isonychia (Slate Drakes) Hatch
		Insects which produce a single generation with two distinct peaks (like the June and September hatches of Isonychia bicolor mayflies) are not multibrooded, because the fall insects are offspring from the previous fall instead of the current year's spring.
		They are unique among mayflies in that they have extra tuft-shaped gills at the base of their fore legs, a structure normally found in stoneflies.
		Abdomens: The rear and usually the longest (ten-segmented in mayflies) portion of an insect's body, to which the tails are attached.

	Cornell News: Mayflies are Paleobarometers
		Maturing into adults after a year or more as water-dwelling larvae, mayflies perform a mating dance by beating their wings 20 to 30 times a second to rise in the air.
		Most mayfly species live only a few days as adults, but the occasional insect that isn't eaten by predators or otherwise recycled sometimes lands in soft sediment with a chance of becoming a well-preserved fossil.
		"Mayflies are particularly good subjects because their flight mechanism is relatively simple and easy to characterize and because they are a very ancient group," he said.

	Hatches Magazine - Mayfly Identification
		Mayflies are unique in the insect world, in that they have more than one winged lifestage, the dun (sub-adult or subimago), and the spinner (adult or imago).
		The body of a mayfly is measured from the front of the head to the end of the abdomen, excluding tails.
		Some mayflies have wings that are plain (uniform in color), and others have wings that are marked or mottled (contrasting in color).

	Mayfly hatch on Kentucky Lake
		Millions of tiny mayflies appear from out of the blue and literally every specie of fish benefits from this natural buffet.
		Mayfly hatches have already been underway on Kentucky Lake and should continue throughout July and into early August.
		Triggered by the warmer weather, rising surface temperatures and other factors known only to Mother Nature, the larva wiggle from the substrate and emerge, leaving a floating husk on the lake surface.

	Mayfly Adult (Site not responding. Last check: )
		Many mayfly species are clumsy swimmers at best, and combine that with shucking their outer nymph skin, they become a flailing treat for the waiting trout.
		The mayfly cannot fold their wings down, which also lend to their visibility for the waiting trout.
		This is the stage where fly fisherman typically use dry flies to imitate the mayfly.

	MAYFLY NYMPH
		Mayfly Nymphs live under stones in fast-flowing water or among plants in slow streams.
		Mayfly Nymphs are either herbivores (herb-ee-vorz), eating only plant matter, or detritivores (det-try-tee-vorz), feeding on decaying material.
		Mayfly Nymphs are sensitive to low levels of oxygen in the water.

	Mayfly
		The thorax and the abdomen of mayflies are bare and often shiny.
		Immature mayflies (naiads) have long legs and plate-like gills on the sides of the abdomen, they usually have three long thin tail projections (cerci) but a few species only have two.
		Mayfly immatures (naiads) are aquatic and feed by scavenging small pieces of organic matter such as plant material or algae and debris that accumulate on rocks or other substrates in streams.

		Mayflies are excellent biomonitoring organisms because they are sensitive to pollution and are found in areas of good water quality.
		Adult and larval mayflies are often consumed by birds, spiders, bullfrogs (Rana catesbeiana) and fishes, such as trout (Salmonidae), bass (Centrarchidae) and pickerel (Esox spp.).
		A mayfly larva can be easily distinguished from other aquatic larvae by two or three long "tails" located at the end of the abdomen.

	Mayfly - Heptagenia longicauda - ARKive
		All adult mayflies, which are very short-lived, fly weakly on their gauzy, delicate wings.
		The wings are not folded over the body when at rest, but are held aloft; this characteristic has earned mayflies the alternative name of ‘upwing flies’.
		Mayflies are so called because in many species the adults emerge in May. They are not true flies, however, but belong to the order Ephemeroptera, the most primitive group of winged insects.

	Ephemera danica - Mayfly
		Living in tunnels in the beds of rivers and lakes, mayfly nymphs have specially adapted breathing filaments which they wave back and forth to create a current over their backs.
		Egg-laying mayfly spinners, larger and paler than the males, fly a foot or so above the surface touching down periodically to release a batch of eggs.
		Once all of their eggs have been expended, the spinners tire and fall to the surface, where they flutter a while before dying in the 'spent gnat' position.
