The larvae of Permoplectoptera still had 9 pairs of abdominal gills, and the adults still had long hindwings. Maybe the fossil family Cretereismatidae from the Lower Cretaceous Crato Formation of Brazil also belongs as the last offshoot to Permoplectoptera. The Crato outcrops otherwise yielded fossil specimens of modern mayfly families or the extinct but modern family Hexagenitidae.
However, from the same locality the strange larvae and adults of the extinct family Mickoleitiidae order Coxoplectoptera have been described,  which represents the fossil sister group of modern mayflies, even though they had very peculiar adaptations such as raptorial forelegs. The oldest mayfly inclusion in amber is Cretoneta zherichini Leptophlebiidae from the Lower Cretaceous of Siberia.
In the much younger Baltic amber numerous inclusions of several modern families of mayflies have been found Ephemeridae, Potamanthidae, Leptophlebiidae, Ametropodidae, Siphlonuridae, Isonychiidae, Heptageniidae, and Ephemerellidae. Grimaldi and Engel, reviewing the phylogeny in , commented that many cladistic studies had been made with no stability in Ephemeroptera suborders and infraorders; the traditional division into Schistonota and Pannota was wrong because Pannota is derived from the Schistonota.
They recovered the Baetidae as sister to the other clades. They found that the Asian genus Siphluriscus was sister to all other mayflies.
A Fly's Life Cycle
Some existing lineages such as Ephemeroidea , and families such as Ameletopsidae, were found not to be monophyletic , through convergence among nymphal features. The following traditional classification is based on Peters and Campbell , in Insects of Australia. Bloodless and many footed animals, whether furnished with wings or feet, move with more than four points of motion; as, for instance, the dayfly ephemeron moves with four feet and four wings: The River Bug on the Black Sea at midsummer brings down some thin membranes that look like berries out of which burst a four-legged caterpillar in the manner of the creature mentioned above, but it does not live beyond one day, owing to which it is called the hemerobius.
Maerten de Vos similarly illustrated a mayfly in his depiction of the fifth day of creation, amongst an assortment of fish and water birds. Smith argue that the image provides "an explicit link between heaven and earth.. Myriads of May-flies appear for the first time on the Alresford stream. The air was crowded with them, and the surface of the water covered. Large trouts sucked them in as they lay struggling on the surface of the stream, unable to rise till their wings were dried Their motions are very peculiar, up and down for so many yards almost in a perpendicular line.
The mayfly has come to symbolise the transitoriness and brevity of life. In shoals the hours their constant numbers bring Like insects waking to th' advancing spring; Which take their rise from grubs obscene that lie In shallow pools, or thence ascend the sky: Such are these base ephemeras, so born To die before the next revolving morn. The theme of brief life is echoed in the artist Douglas Florian's poem, "The Mayfly". Another literary reference to mayflies is seen in The Epic of Gilgamesh , one of the earliest surviving great works of literature.
The briefness of Gilgamesh's life is compared to that of the adult mayfly. Mayflies are the primary source of models for artificial flies, hooks tied with coloured materials such as threads and feathers, used in fly fishing. For example, the flies known as "emergers" in North America are designed by fly fishermen to resemble subimago mayflies, and are intended to lure freshwater trout. A large number of these species have common names among fly fishermen, who need to develop a substantial knowledge of mayfly "habitat, distribution, seasonality, morphology and behavior" in order to match precisely the look and movements of the insects that the local trout are expecting.
Izaak Walton describes the use of mayflies for catching trout in his book The Compleat Angler ; for example, he names the "Green-drake" for use as a natural fly, and "duns" mayfly subimagos as artificial flies. Skues with his book Minor Tactics of the Chalk Stream. In the book, Skues discusses the use of duns to catch trout. During the weekend of June 13—14, , a large swarm of mayflies caused several vehicular accidents on the Columbia—Wrightsville Bridge , carrying Pennsylvania Route across the Susquehanna River between Columbia and Wrightsville, Pennsylvania.
The bridge had to be closed to traffic twice during that period due to impaired visibility and obstructions posed by piles of dead insects. Mayflies are consumed in several cultures and are estimated to contain the most raw protein content of any edible insect by dry weight. In Malawi, kungu, a paste of mayflies Caenis kungu and mosquito is made into a cake for eating. Adult mayflies are collected and eaten in many parts of China and Japan. Near Lake Victoria, Povilla mayflies are collected, dried and preserved for use in food preparations. The Seddon Mayfly , which was constructed in , was an aircraft that was unsuccessful in early flight.
The first aircraft designed by a woman, Lillian Bland , was titled the Bland Mayfly.

In pres France, "chute de manne" was obtained by pressing mayflies into cakes and using them as bird food and fishbait. Their exoskeleton contains chitin, which has applications in these industries. Mayfly larvae do not survive in polluted aquatic habitats and, thus, have been chosen as bioindicators, markers of water quality in ecological assessments. In marketing, Nike produced a line of running shoes in titled "Mayfly".
The shoes were designed with a wing venation pattern like the mayfly and were also said to have a finite lifetime. From Wikipedia, the free encyclopedia.

How Houseflies Work
Retrieved 7 March Insecta , with comments on the phylogeny of the stem group of mayflies Ephemeroptera ". This way, we can sort through the flies and pick out the ones with colored eyes, most commonly orange. Flies with two genes have darker orange eyes because the color adds up, which is great for me. I sort through the flies under a microscope using a paintbrush, and then brush the flies I need for my experiments into smaller vials to separate them.
These are bottles filled with a mixture of water, ethanol, apple cider vinegar, and a drop of dish detergent. These also make great traps in the home to take care of fruit fly infestations. For some people in our lab, this means loading the live flies into machines that track their activity for sleep or memory studies. For others, such as myself, it means dissecting out the brains from individual flies or in some studies, the larvae instead , and performing experiments on the brains instead of live animals.
As you can imagine, it takes a pretty long time to learn how to dissect out the tiny brain from these insects.

The final brain is too small to see by eye though the most experienced among us can point out the tiny white dot in a drop of water. Close-up of the imaging set-up for dissected fly brains. Fresh hemolymph-like solution is being perfused in from the right to replace the old solution being vacuumed out on the left. A 60x magnification objective is shining a tiny beam of fluorescent light into the dish.
The brain-in-a-dish is placed under a microscope with a fluorescent light so that the fluorescent marker in the brain glows. During the experiments, I make sure that fresh hemolymph-like solution is flowing over the brain and being vacuumed out on the other side to keep the brain healthy, and sometimes I use this system to add in drugs which can affect activity in the neurons. This allows me to manipulate specific neurons and study how it affects communication between them.
