Drosophila deflecta is a species of fruit fly in the Drosophila quinaria species group. [1] [2] [3] [4] Larvae are scavengers of Nuphar water lilies. [5]
Drosophila is a genus of flies, belonging to the family Drosophilidae, whose members are often called "small fruit flies" or pomace flies, vinegar flies, or wine flies, a reference to the characteristic of many species to linger around overripe or rotting fruit. They should not be confused with the Tephritidae, a related family, which are also called fruit flies ; tephritids feed primarily on unripe or ripe fruit, with many species being regarded as destructive agricultural pests, especially the Mediterranean fruit fly.
The Drosophilidae are a diverse, cosmopolitan family of flies, which includes species called fruit flies, although they are more accurately referred to as vinegar or pomace flies. Another distantly related family of flies, Tephritidae, are true fruit flies because they are frugivorous, and include apple maggot flies and many pests. The best known species of the Drosophilidae is Drosophila melanogaster, within the genus Drosophila, also called the "fruit fly." Drosophila melanogaster is used extensively for studies concerning genetics, development, physiology, ecology and behaviour. Many fundamental biological mechanisms were discovered first in D. melanogaster. The fruit fly is mostly composed of post-mitotic cells, has a very short lifespan, and shows gradual aging. As in other species, temperature influences the life history of the animal. Several genes have been identified that can be manipulated to extend the lifespan of these insects. Additionally, Drosophila subobscura, also within the genus Drosophila, has been reputed as a model organism for evolutionary-biological studies, along with D. sechellia for the evolution of host specialization on the toxic noni fruit and Scaptomyza flava for the evolution of herbivory and specialist on toxic mustard leaves.
The Drosophilinae are the largest subfamily in the Drosophilidae. The other subfamily is the Steganinae.
The paraphyletic subgenus Sophophora of the genus Drosophila was first described by Alfred Sturtevant in 1939. It contains the best-known drosophilid species, Drosophila melanogaster. Sophophora translates as carrier (phora) of wisdom (sophos). The subgenus is paraphyletic because the genus Lordiphosa and the species Hirtodrosophila duncani are also placed within this subgenus.
Drosophila busckii is a species of fruit fly that is native to North America, though it now also occurs in Asia, Europe, Oceania and South America. It can be identified by the presence of dark stripes on the thorax and the wings being transparent with no markings. Mostly it is associated with rotten potatoes. In the laboratory they are normally reared on Wheeler-Clayton food.
The subgenus Dorsilopha belongs to genus Drosophila and consists of four species. The phylogenetic position of this group has been unclear for a long time, but recent studies have shown that the subgenus is positioned ancestral to the subgenus Drosophila.
The genus Zaprionus belongs to the family fruit fly Drosophilidae and is positioned within the paraphyletic genus Drosophila. All species are easily recognized by the white longitudinal stripes across the head and thorax. The genus is subdivided in two subgenera, based on the presence of an even or odd number of white stripes. The species of the genus can be found in Africa and Southern Asia. One species, Zaprionus indianus, has invaded the New World.
Drosophila repleta is a species of vinegar fly in the family Drosophilidae.
Chymomyza is a genus of vinegar flies.
Drosophila tripunctata is a species of vinegar fly in the Immigrans-tripunctata radiation of the subgenus Drosophila.
Drosophila guttifera is a species of vinegar fly in the Drosophila quinaria species group. Like many quinaria group species, D. guttifera feeds on rotting mushrooms.
Scaptomyza is a genus of vinegar flies, insects in the family Drosophilidae. As of 2022, there are 273 described species of Scaptomyza. Of those, 148 are endemic to the Hawaiian archipelago. This genus is part of the species-rich lineage of Hawaiian Drosophilidae, and is the sister lineage to the endemic Hawaiian Drosophila. The genus Scaptomyza is one of several nested within the paraphyletic genus Drosophila.
Drosophila immigrans is a species of vinegar fly in the family Drosophilidae. Drosophila immigrans is a member of the Immigrans-tripunctata radiation of the subgenus Drosophila. It is related to the Drosophila quinaria and Drosophila testacea species groups, and the fellow Immigrans species group member Drosophila albomicans. Drosophila immigrans has been used in evolutionary studies to understand how viruses evolve with their hosts.
Drosophila quinaria is a species of fruit fly in the Drosophila quinaria species group. Most Quinaria group species feed largely on mushrooms. However D. quinaria instead eats decaying vegetative matter, a trait it evolved independently.
Drosophila cardini is a species of fruit fly in the Drosophila cardini species group.
Drosophila albomicans is a species of vinegar fly in the family Drosophilidae. Drosophila albomicans is a member of the Immigrans-tripunctata radiation of the subgenus Drosophila. The D. albomicans genome was first sequenced in 2012 to study the evolution of novel sex chromosomes, a characteristic this species is best known for. One commonly accepted definition of the biological species concept is that individuals or populations are members of different species if they are incapable of successful interbreeding. While D. albomicans and Drosophila nasuta are commonly referred to as distinct species, there appears to be little to no sexual isolation between these two Drosophila species. Instead, behavioural differences appear to reproductively isolate these two species.
The Hawaiian Drosophilidae are a lineage of flies within the genus Drosophila. This monophyletic clade includes all of the endemic Hawaiian Drosophila and all members of the genus Scaptomyza, which contains both Hawaiian and non-Hawaiian species. The Hawaiian Drosophilidae are descended from a common ancestor estimated to have lived 25 million years ago. Species of Hawaiian Drosophilidae flies have been studied as models of speciation and behavioral evolution. Along with other members of the native Hawaiian ecosystem, the conservations status of many species of Hawaiian Drosophilidae is threatened by habitat loss and introduced predators, among other factors.
Drosophila aglaia is an endangered species of fly from Hawaii. This species is a member of the aglaia subgroup of the picture-wing clade of Hawaiian Drosophilidae. It is only found on the island of Oahu, and has not been observed since 1997, when it was found in Palikea.
Drosophila musaphilia is an endangered species of fly from Hawaii, in the species rich lineage of Hawaiian Drosophilidae. It is only found on the island of Kauai. The last reported sighting of this species was in 1988.
Drosophila obatai is an endangered species of fly from Hawaii, in the species rich lineage of Hawaiian Drosophilidae. It is only found on the island of Oahu. D. obatai is part of the orphnopeza subgroup in the picture-wing clade, and is closely related to D. sodomae, a fly found on the islands of Maui and Molokai.
