Mayflies (also known as Canadian soldiers in the United States, or shadflies or fishflies in Canada and Michigan; also up-winged flies in the United Kingdom ) are aquatic insects belonging to the order Ephemeroptera.
The Ephemeroptera, or mayflies, are a small but diverse order of amphinotic insects associated with liquid freshwater worldwide. They are nearly cosmopolitan, except for Antarctica and some very remote islands. The existence of the subimago stage is unique among extant insects.
Ephemeroptera constitutes a small order of extant insects, with approximately 40 families, 440 genera, and 3330 species (Table 34.1). The state of our knowledge varies considerably depending on the geographic region.
Ephemeroptera. Arguably the most primitive of the winged insects, mayflies are generally recognised by their triangular fore wings held vertically above the body at rest.
