Ephemerelloidea
''Ephemerelloidea'' is a superfamily of mayflies in the suborder Pannota. It is a basal group of mayflies with a worldwide distribution. Members of this super-family can be distinguished from those of Caenoidea by the fact that the gills of the nymphs are not filamentous. The following families are recognised: *Ephemerellidae *Leptohyphidae Leptohyphidae is a family of mayfly, mayflies with some 140 described species in 12 genera.

Mayfly
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 ...

Pannota
Pannota is a suborder of mayflies. One of the differences between this suborder and its sister group Schistonota concerns the degree of fusion of the wing pads in the final-stage nymph; in Schistonota, the degree of fusion along the mesothorax is more than half the fore-wing length while in Pannota the degree of fusion is less than half that length. Other differences between the two groups include the morphology of the gills and also behavioural differences. Schistonota nymphs are mostly active swimmers, burrowers and sprawlers, while Pannota nymphs are more passive, slow-moving crawlers. The following superfamilies and families are recognised: *Superfamily Caenoidea **Baetiscidae **Caenidae ** Neoephemeridae **Prosopistomatidae *Superfamily Ephemerelloidea **Ephemerellidae **Leptohyphidae **Tricorythidae Tricorythidae is a family of mayflies in the order Ephemeroptera.

Caenoidea
Caenoidea is a superfamily of mayflies in the suborder Pannota. Members of this superfamily can be distinguished from those of Ephemerelloidea by the fact that the gills of the nymphs are filamentous. The following families are recognised: *Baetiscidae *Caenidae * Neoephemeridae *Prosopistomatidae Prosopistomatidae is a family of mayflies. There is one extant genus, '' Prosopistoma,'' with several dozen species found across Afro-Eurasia and Oceania. They are noted for their unusual beetle-shaped larvae, which live beneath rocks and stones ... References {{Taxonbar, from=Q10439230 Mayflies Insect superfamilies ...

Taxonomic Rank
In biological classification, taxonomic rank is the relative level of a group of organisms (a taxon) in an ancestral or hereditary hierarchy. A common system consists of species, genus, family, order, class, phylum, kingdom, domain. While older approaches to taxonomic classification were phenomenological, forming groups on the basis of similarities in appearance, organic structure and behaviour, methods based on genetic analysis have opened the road to cladistics. A given rank subsumes under it less general categories, that is, more specific descriptions of life forms. Above it, each rank is classified within more general categories of organisms and groups of organisms related to each other through inheritance of traits or features from common ancestors. The rank of any ''species'' and the description of its ''genus'' is ''basic''; which means that to identify a particular organism, it is usually not necessary to specify ranks other than these first two.

Ephemerellidae
Ephemerellidae are known as the spiny crawler mayflies. They are a family of the order Ephemeroptera. There are eight genera consisting of a total 90 species (Merritt & Cummins). They are distributed throughout North America as well as the UK. Their habitat is lotic-erosional, they are found in all sizes of flowing streams on different types of substrates where there is reduced flow. They are even found on the shores of lakes and beaches where there is wave action present. They move by swimming and clinging, they are very well camouflaged. Most species have one generation per year. They are mostly collector-gatherers. If threatened by a predator, the larva will raise its three tails in a "scorpion posture" to appear larger. It will then project its tails in front and poke the enemy. Most species are sensitive to disturbance. In the UK, the most commonly recorded species is ''Seratella ignita''. The nymph of this animal is often distinguished from other Mayflies by the darker ban ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
