The following families are recognised: * Behningiidae *Ephemeridae Ephemeridae is a family of mayflies with about 150 described species found throughout the world except Australia and Oceania.

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 ...

Behningiidae
Behningiidae is a family of mayflies. It is a primitive family; the nymphs burrow in the sediment but lack tusks on their mandibles, and the forelegs are not modified for burrowing. The gills are ventral, and the ones on the first abdominal segment are single and are longer than the gills on the other segments. The forelegs are palp-like and the other two pairs of legs are modified to protect the gills. The family is holarctic The Holarctic realm is a biogeographic realm that comprises the majority of habitats found throughout the continents in the Northern Hemisphere. It corresponds to the floristic Boreal Kingdom. It includes both the Nearctic zoogeographical region ... in distribution. The genus ''Dolania'' occurs in North America and the other three genera occur in northern Europe and Asia. Genera The family includes the following genera: * †'' Archaeobehningia'' Tshernova, 1977 * '' Behningia'' Lestage, 1930 * '' Dolania'' Edmunds & Traver, 1959 * '' Protobehningia'' T ...

Ephemera Danica
''Ephemera danica'', the green drake or green drake mayfly, is a species of mayfly in the genus '' Ephemera''. Description ''Ephemera danica'' can reach an imago size of in males, while females are larger, reaching . This mayfly, with its characteristic markings and three tails ( Cerci), is the most commonly seen of British Ephemeridae. Imago wings are translucent with dark veining, while in subimago they are dull and yellowish with brown veins. Moreover, forelegs and the tails of the spinners are very much longer than in duns. Mouthparts are non-functional, as adults do not feed. These insects are part of the aerial plankton and usually they are food for swallows, trouts and many amphibians and spiders. Life cycle The life cycle usually takes one or two years, but sometimes the developing nymphal forms may last for up to three years. Nymphs can reach about of length. They dig tunnels into the gravel in the beds of rivers and feed by filtering organic detritus. They emerge in ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 (biology), family, order (biology), order, class (biology), class, phylum (biology), phylum, kingdom (biology), kingdom, domain (biology), 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 phenotypic trait, traits or features from common ancestors. The rank of any ''species'' and the description of its ''genus'' is ''basic''; which means that to iden ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ephemeridae
Ephemeridae is a family of mayflies with about 150 described species found throughout the world except Australia and Oceania. These are generally quite large mayflies (up to 35 mm) with either two or three very long tails. Many species have distinctively patterned wings. Ephemerids breed in a wide range of waters, usually requiring a layer of silt as the nymphs have strong legs which are adapted for burrowing (the group is sometimes known as burrowing mayflies). The nymphs are largely carnivorous and collect their food either through predation or scavenging Scavengers are animals that consume dead organisms that have died from causes other than predation or have been killed by other predators. While scavenging generally refers to carnivores feeding on carrion, it is also a herbivorous feeding ....

Palingeniidae
Palingeniidae is a family of mayflies, members of which are known as spiny-headed burrowing mayflies. These are generally quite large mayflies with more than four longitudinal cross-veins on their wings. Males have short, wide pronotums and the legs are well-developed in both sexes. The cerci (tails) on females are shorter than the body. The nymphs A nymph ( grc, νύμφη, nýmphē, el, script=Latn, nímfi, label=Modern Greek; , ) in ancient Greek folklore is a minor female nature deity.
