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 Family (from la, familia) is a group of people related either by consanguinity (by recognized birth) or affinity (by marriage or other relationship). The purpose of the family is to maintain the well-being of its members and of society.

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" (emer ...

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 Neoephemeridae is a family of large squaregill mayflies in the order Ephemeroptera.

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.

Mesothorax
The mesothorax is the middle of the three segments of the thorax of hexapods, and bears the second pair of legs. Its principal sclerites (exoskeletal plates) are the mesonotum (dorsal), the mesosternum (ventral), and the mesopleuron (lateral) on each side. The mesothorax is the segment that bears the forewings in all winged insects, though sometimes these may be reduced or modified, as in beetles (Coleoptera) or Dermaptera, in which they are sclerotized to form the elytra ("wing covers"), and the Strepsiptera, in which they are reduced to form halteres that attach to the mesonotum. All adult insects possess legs on the mesothorax. In some groups of insects, the mesonotum is hypertrophied, such as in Diptera, Hymenoptera, and Lepidoptera), in which the anterior portion of the mesonotum (called the mesoscutum, or simply "scutum") forms most of the dorsal surface of the thorax. In these orders, there is also typically a small sclerite attached to the mesonotum that covers the wing b ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Family (biology)
Family ( la, familia, plural ') is one of the eight major hierarchical taxonomic ranks in Linnaean taxonomy. It is classified between order and genus. A family may be divided into subfamilies, which are intermediate ranks between the ranks of family and genus. The official family names are Latin in origin; however, popular names are often used: for example, walnut trees and hickory trees belong to the family Juglandaceae, but that family is commonly referred to as the "walnut family". What belongs to a family—or if a described family should be recognized at all—are proposed and determined by practicing taxonomists. There are no hard rules for describing or recognizing a family, but in plants, they can be characterized on the basis of both vegetative and reproductive features of plant species. Taxonomists often take different positions about descriptions, and there may be no broad consensus across the scientific community for some time. The publishing of new data and opin ...

Baetiscidae
Baetiscidae is a family of mayflies. It contains a single extant genus, '' Baetisca'', native to North America with around 12 species. The family is noted for their spined armoured larvae, which live in flowing water pools and on the edges of streams where they are detritivores, consuming fine particles of organic matter. Two other extinct genera are known, extending back to the Early Cretaceous. They are closely related to Prosopistomatidae which have unusual, beetle-like nymphs as well as the extinct genus '' Cretomitarcys,'' with the three groups constituting the clade Carapacea. Genera These two genera belong to the family Baetiscidae: * '' Baetisca'' Walsh, 1862 * †'' Balticobaetisca'' Staniczek & Bechly, 2002 Baltic amber, Eocene * †'' Protobaetisca'' Staniczek 2007 Crato Formation The Crato Formation is a geologic formation of Early Cretaceous (Aptian) age in northeastern Brazil's Araripe Basin.

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 ...
