List Of Obsolete Names In Diptera
{{short description, none The higher-level classification of the insect order Diptera is in a constant state of flux, and over the last several decades, a vast number of names have been variously proposed, rejected, had their definitions changed, or altered spelling. Keeping track of all of these names is a challenging task, especially as there is no consensus as to the proper classification that should be used for this order, as well as reflecting a more fundamental challenge to the entire underlying principles of classification, which is especially evident among Dipteran systematists. The purpose of this article is to serve as a reference in situations where a reader may encounter an obsolete name in a printed or online resource, and otherwise be unable to find it. Secondarily, this list also contains names referring to fossil taxa, whose placement into modern classifications is generally untenable, as classifications increasingly rely on molecular phylogenetics, which excludes fos ...

Insect
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. ...
