Caenidae
Caenidae, or the small squaregill mayflies, is a family of insects consisting of 5 genera comprising 26 individual species. They are found throughout the world in lotic, depositional environments, and they are sprawlers. Caenids occur in quiet and even stagnant water and are often overlooked because they are so small. They like to live in silty bottoms, and their gills are specially adapted for such environments. References Mayflies Insect families {{mayfly-stub ...

Mayflies
Mayflies (also known as shadflies or fishflies in Canada and the upper Midwestern United States, as Canadian soldiers in the American Great Lakes region, and as up-winged flies in the United Kingdom) are aquatic insects belonging to the order Ephemeroptera. This order is part of an ancient group of insects termed the Palaeoptera, which also contains dragonflies and damselflies. Over 3,000 species of mayfly are known worldwide, grouped into over 400 genera in 42 families. Mayflies have ancestral traits that were probably present in the first flying insects, such as long tails and wings that do not fold flat over the abdomen. Their immature stages are aquatic fresh water forms (called "naiads" or "nymphs"), whose presence indicates a clean, unpolluted and highly oxygenated aquatic environment. They are unique among insect orders in having a fully winged terrestrial preadult stage, the subimago, which moults into a sexually mature adult, the imago. Mayflies "hatch" (emerge as ...

Caenis (mayfly)
''Caenis'' is a genus of mayflies. They are very small in size, sometimes with a body of only an 1/8 of an inch (). Distribution and ecology ''Caenis'' is one of the most abundant mayfly genera of the Holarctic. Larvae can occur in high densities on the bottoms of shallow ponds and lakes up to an altitude of 1800 meters in the lps Densities of 700-1700 larvae per square meter have been reported for ''C. luctuosa'' and ''C. horaria'' on bottoms covered with organic detritus or decaying leaves. Densities on mineral sediments are an order of magnitude lower (4-330 animals per square meter).
