Pontomyia
''Pontomyia'' is a genus of flightless marine midges belonging to the subfamily Chironominae in the Chironomidae The Chironomidae (informally known as chironomids, nonbiting midges, or lake flies) comprise a family of nematoceran flies with a global distribution. They are closely related to the Ceratopogonidae, Simuliidae, and Thaumaleidae. Many specie ... family. Insects in marine environments are extremely rare while flightlessness, extreme sexual dimorphism, and an extremely short adult life span (of less than 3 hours) contribute to making these midges unusual among insects. They are known from the shores of islands in the Indian, Atlantic and Pacific Oceans. The genus was described by Edwards in 1926 from Samoa. They were originally described as being submarine midges. Four species were described in the genus ''P. natans'' (Edward 1924), ''P. cottoni'' (Wormersley 1937), ''P. pacifica'' (Tokunaga 1964), and ''P. oceana'' (Tokunaga 1964) but DNA analysis determined that ...

Chironomidae
The Chironomidae (informally known as chironomids, nonbiting midges, or lake flies) comprise a family of nematoceran flies with a global distribution. They are closely related to the Ceratopogonidae, Simuliidae, and Thaumaleidae. Many species superficially resemble mosquitoes, but they lack the wing scales and elongated mouthparts of the Culicidae. The name Chironomidae stems from the Ancient Greek word ''kheironómos'', "a pantomimist". Common names and biodiversity This is a large taxon of insects; some estimates of the species numbers suggest well over 10,000 world-wide. Males are easily recognized by their plumose antennae. Adults are known by a variety of vague and inconsistent common names, largely by confusion with other insects. For example, chironomids are known as "lake flies" in parts of Canada and Lake Winnebago, Wisconsin, but "bay flies" in the areas near the bay of Green Bay, Wisconsin. They are called "sand flies", "muckleheads", "muffleheads", "Canadian so ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Frederick Wallace Edwards
Frederick Wallace Edwards FRS (28 November 1888 in Fletton, Peterborough – 15 November 1940 in London), was an English entomologist. Edwards was known in the field of entomology for his work on Diptera. Edwards worked in the British Museum (Natural History) which contains his collections made on his expeditions to Norway and Sweden (1923), Switzerland and Austria (1925), Argentina and Chile (1926/27), with Raymond Corbett Shannon, Corsica and USA (1928), the Baltic (1933), Kenya and Uganda (1934), with Ernest Gibbins, and the Pyrenees (1935). He was able to oversee publication of Alwyn M. Evan's monograph on ''The Mosquitoes of the Ethiopian Region'' after her death in 1937. Among the unusual insects that he described was the flightless marine midge ''Pontomyia''. The mosquito genus ''Fredwardsius'' is named to honor his work establishing the generic and subgeneric framework which forms the basis for modern day systematics of the Culicidae Mosquitoes (or mosquitos) ...

Animalia
Animals are multicellular, eukaryotic organisms in the biological kingdom Animalia. With few exceptions, animals consume organic material, breathe oxygen, are able to move, can reproduce sexually, and go through an ontogenetic stage in which their body consists of a hollow sphere of cells, the blastula, during embryonic development. Over 1.5 million living animal species have been described—of which around 1 million are insects—but it has been estimated there are over 7 million animal species in total. Animals range in length from to . They have complex interactions with each other and their environments, forming intricate food webs. The scientific study of animals is known as zoology. Most living animal species are in Bilateria, a clade whose members have a bilaterally symmetric body plan. The Bilateria include the protostomes, containing animals such as nematodes, arthropods, flatworms, annelids and molluscs, and the deuterostomes, containing the echinode ...

Arthropoda
Arthropods (, (gen. ποδός)) are invertebrate animals with an exoskeleton, a Segmentation (biology), segmented body, and paired jointed appendages. Arthropods form the phylum Arthropoda. They are distinguished by their jointed limbs and Arthropod cuticle, cuticle made of chitin, often Mineralization (biology), mineralised with calcium carbonate. The arthropod body plan consists of segments, each with a pair of appendages. Arthropods are bilaterally symmetrical and their body possesses an exoskeleton, external skeleton. In order to keep growing, they must go through stages of moulting, a process by which they shed their exoskeleton to reveal a new one. Some species have wings. They are an extremely diverse group, with up to 10 million species. The haemocoel, an arthropod's internal cavity, through which its haemolymph – analogue of blood – circulates, accommodates its interior Organ (anatomy), organs; it has an open circulatory system. Like their exteriors, the internal or ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Insecta
Insects (from Latin ') are pancrustacean hexapod invertebrates of the class Insecta. They are the largest group within the arthropod phylum. Insects have a chitinous exoskeleton, a three-part body ( head, thorax and abdomen), three pairs of jointed legs, compound eyes and one pair of antennae. Their blood is not totally contained in vessels; some circulates in an open cavity known as the haemocoel. Insects are the most diverse group of animals; they include more than a million described species and represent more than half of all known living organisms. The total number of extant species is estimated at between six and ten million; In: potentially over 90% of the animal life forms on Earth are insects. Insects may be found in nearly all environments, although only a small number of species reside in the oceans, which are dominated by another arthropod group, crustaceans, which recent research has indicated insects are nested within. Nearly all insects hatch from eggs. I ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Diptera
Flies are insects of the order Diptera, the name being derived from the Greek δι- ''di-'' "two", and πτερόν ''pteron'' "wing". Insects of this order use only a single pair of wings to fly, the hindwings having evolved into advanced mechanosensory organs known as halteres, which act as high-speed sensors of rotational movement and allow dipterans to perform advanced aerobatics. Diptera is a large order containing an estimated 1,000,000 species including horse-flies, crane flies, hoverflies and others, although only about 125,000 species have been described. Flies have a mobile head, with a pair of large compound eyes, and mouthparts designed for piercing and sucking (mosquitoes, black flies and robber flies), or for lapping and sucking in the other groups. Their wing arrangement gives them great maneuverability in flight, and claws and pads on their feet enable them to cling to smooth surfaces. Flies undergo complete metamorphosis; the eggs are often laid on the l ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Nematocera
The Nematocera (the name means "thread-horns") are a suborder of elongated flies with thin, segmented antennae and mostly aquatic larvae. This group is paraphyletic and contains all flies but species from suborder Brachycera (the name means "short-horns"), which includes more commonly known species as housefly or the common fruit fly. Families in Nematocera include mosquitoes, crane flies, gnats, black flies, and a multiple groups of families described as midges. The Nematocera typically have fairly long, fine, finely-jointed antennae. In many species, such as most mosquitoes, the female antennae are more or less threadlike, but the males have spectacularly plumose antennae. The larvae of most families of Nematocera are aquatic, either free-swimming, rock-dwelling, plant-dwelling, or luticolous. Some families however, are not aquatic; for instance the Tipulidae tend to be soil-dwelling and the Mycetophilidae feed on fungi such as mushrooms. Unlike most of the Brachycera, the ...

Culicomorpha
The Culicomorpha are an infraorder of Nematocera, including mosquitoes, black flies, and several extant and extinct families of insects. They originated 176 million years ago, in the Triassic period. There are phylogenetic patterns that are used to interpret bionomic features such as differences in the nature of blood-feeding by adult females, daytime or nighttime feeding by adult females, and occurrence of immature stages in aquatic habitats. Most adult, females lay their eggs on bodies of water. Some are restricted to very clean waters, but others can tolerate highly polluted environments. Many adults transmit parasites or diseases that can be debilitating or fatal to humans, such as malaria and West Nile virus. Biting midges can transmit an extensive range of pathogens of veterinary importance, including Akabane virus, bovine ephemeral fever virus, Schmallenberg virus, African horse sickness virus, epizootic haemorrhagic disease virus, and bluetongue virus.

Chironomoidea
The Chironomoidea are a superfamily within the order Diptera, suborder Nematocera, infraorder Culicomorpha. This superfamily contains the families Chironomidae, Ceratopogonidae, Simuliidae, and Thaumaleidae. Description Chironomoidea have four life stages: the egg, the worm-like larva, the pupa and the winged adult. Ecology Chironomoidea show a range of habitats and diets. Using the family Chironomidae as an example, larvae occur most commonly in aquatic vegetation and benthic debris, but also in sand covered in fine organic material, pools on granite outcrops, wood snags, muddy lake beds and hygropetric seepages. Pupae may occur near the surface of water, in submerged substrata or amongst benthic debris. Larvae may feed on deposits of organic detritus (gathering collectors), filter diatoms and fine particles of detritus from the water column (filtering collectors), chew or bore into live or dead plant matter (shredders), scrape algae, bacteria and diatoms from surfaces (scr ...
