Wingless Insect
There are various disparate groups of wingless insects. Apterygota are a subclass of small, agile insects, distinguished from other insects by their lack of wings in the present and in their evolutionary history. They include Thysanura (silverfish and firebrats). Some species lacking wings are members of insect order (biology), orders that generally do have wings. Some aptery, do not grow wings at all, having "lost" the possibility in the remote past. Some have brachyptery, reduced wings that are not useful for flying. Some develop wings but shed them after they are no longer useful. Other groups of insects may have castes with wings and castes without, such as ants. Ants have alate queens and males during the mating season and wingless workers, which allows for smaller workers and more populous colonies than comparable winged wasp species. Wingless flies True fly, flies are insects of the order (biology), order Diptera. The name is derived from the Greek ''di-'' = two, and ''ptera ...

Apterygota
The name Apterygota is sometimes applied to a former Subclass (biology), subclass of small, agile insects, distinguished from other insects by their lack of wings in the present and in their evolutionary history; notable examples are the silverfish, the firebrat, and the Archaeognatha, jumping bristletails. Their first known occurrence in the fossil record is during the Devonian period, 417–354 million years ago. The group Apterygota is not a clade; it is paraphyletic, and not recognized in modern classification schemes. As defined, the group contains two separate clades of wingless insects: Archaeognatha comprises jumping bristletails, while Zygentoma comprises silverfish and firebrats. The Zygentoma are in the clade Dicondylia with winged insects, a clade that includes all other insects, while Archaeognatha is sister to this lineage.A. Blanke, M. Koch, B. Wipfler, F. Wilde, B.

Mystacinobia Zelandica
The New Zealand bat fly (''Mystacinobia zelandica'') is a small, wingless insect which lives in a commensal relationship with the New Zealand lesser short-tailed bat. It is a true fly, in the order Diptera, placed in its own genus, ''Mystacinobia'', and its own family, Mystacinobiidae. Although many other species of bat fly exist throughout the world, the New Zealand bat fly is endemic to the islands of New Zealand.Gibbs, George. (2008). ''Ghosts of Gondwana''. Craig Potton Publishing: Auckland. p16 Unlike other similar looking bat flies, this species is not a parasite and is only phoretic, feeding on bat guano. It appears to be the only insect, parasitic or otherwise, which lives with these bats (fleas, for example, which are common on many other species of bat, are unknown on the short-tailed bat).

Pringleophaga Marioni
''Pringleophaga marioni'' (Marion flightless moth or Subantarctic caterpillar) is a moth of the family Tineidae.

They are named Marion Island (named after Marc-Joseph Marion du Fresne, 1724–1772) and P ....

Operophtera Brumata
The winter moth (''Operophtera brumata'') is a moth of the family Geometridae. It is an abundant species in Europe and the Near East and a famous study organism for evaluating insect population dynamics. It is one of very few lepidopterans of temperate regions in which adults are active in late autumn and early winter. The females of this species are virtually wingless and cannot fly, but the males are fully winged and fly strongly. After the initial frosts of late fall, the females emerge from their pupae, walk to and up trees and emit pheromones in the evening to attract males. After fertilization, they ascend to lay, on average, around 100 eggs each. Typically, the larger the female moth is, the more eggs she lays. The winter moth is considered an invasive species in North America. Nova Scotia, Canada, experienced the first confirmed infestations in the 1930s. It was later accidentally introduced to Oregon in the 1950s and the Vancouver area of British Columbia around 1970. D ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

''Pachythelia villosella'' is a moth of the Psychidae family. It is found in Europe. The wingspan is 13–15 mm for males. Head, thorax, and abdomen pale brownish-ochreous. Forewings and hindwings thinly haired, dark brown or grey brown; veins and base of cilia darker. Females are wingless and have a rounded frontal prominence. Adults are on wing in June and July.

Orgyia Recens
''Telochurus recens'', the scarce vapourer, is a moth of the subfamily Lymantriinae found in Europe. The species was first described by Jacob Hübner in 1819. The wingspan is for the males; the females are wingless. The moth flies from June to July depending on the location. The larvae feed on various deciduous trees, such as ''Crataegus'' and ''Salix'' species. This species has commonly been placed in the genus '' Orgyia'' but molecular analyses support its exclusion from that genus, and placement in the genus ''Telochurus''.Wang, H. et al. (2015).

Larviform Female
Larviform female is a biological phenomenon occurring in some insect species, where the females in the adult stage of metamorphosis resemble the larvae to various degrees, while the male appears more morphologically adult (as imagoes). The resemblance may mean the larviform female has the same coloring as the larvae and/or similar body plans, and may be the result of the female arresting development at earlier stages of ecdysis than males. The female may not pupate at all, as in ''Xenos vesparum''.Erezyilmaz, D.F., Hayward, A., Huang, Y., Paps, J., Acs, Z., Delgado, J.A., Collantes, F., and Kathirithamby, J.

Flightless Fruit Fly
Flightless fruit flies (Order Diptera) encompass a variety of different species of fly, such as ''Drosophila melanogaster'', '' Bactrocera cucurbitae'', ''Bactrocera dorsalis'', and ''Drosophila hydei'', with genetic mutations that cause them to be flightless. These genetic mutations may have different results such as the development of muscles that cannot support flight or even result in the lack of wings entirely. Flightless fly models have been especially useful for the study of human neuromuscular diseases such as spinal muscular atrophy, spinobulbar muscular atrophy, myotonic dystrophy, dystrophinopathies and other inherited neuromuscular diseases. Applications of flightless flies are extremely varied, even being used as test subjects in aeronautical research. Uses for feeding pets Other applications of flightless flies include using them as convenient feeders for a variety of companion animals, usually small reptile Reptiles, as commonly defined, are a group of tetrap ...

Lipoptena Mazamae
''Lipoptena mazamae'', the Neotropical deer ked, is a fly from the family Hippoboscidae. They are blood-feeding parasites of the white-tailed deer - ''Odocoileus virginianus'' in the southeastern United States and Central America, the red brocket deer - ''Mazama americana'' in Mexico to northern Argentina, and also an incidental parasite of domestic cattle, Cougars - ''Puma concolor'', and man. Deer keds are small brown, flattened flies. Females are slightly larger than males, with a body length of 3.5-4.5 mm for females 3 mm for males. They have a tough protective exoskeleton to prevent them from being crushed. They shed their wings upon finding a suitable host. As in all Hippoboscidae, both males and females are blood feeders. They are often misidentified as ticks. The female fly will produce a single larva at a time, retaining the larva internally until it is ready to pupate. The larva feeds on the secretions of a milk gland in the uterus of the female. After three ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pontomyia
''Pontomyia'' is a genus of flightless marine midges belonging to the subfamily Chironominae in the Chironomidae Chironomidae , commonly known as non-biting midges or chironomids , are a family of Nematoceran flies with a global distribution. They are closely related to the families Ceratopogonidae, Simuliidae, and Thaumaleidae. Although many chironomid ... 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 ...
