This longer life span may be associated with the reduced amount of tryptophan converted to kynurenine in vermilion flies. [69] Triple mutant male fruit fly (Drosophila melanogaster) exhibiting black body, vestigial wings, and brown eyes mutations. vg: vestigial- A spontaneous mutation, discovered in 1919 by Thomas Morgan and Calvin Bridges ...
The products of these genes are used in the regulation of morphological features between the wing and the haltere. Ubx also selectively represses one enhancer of the vestigial genes in the proximodistal axis. This gene is important for the development of hindwings in Lepidoptera, and leg development in larvae.

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. [1] Another distantly related family of flies, Tephritidae , are true fruit flies because they are frugivorous, and include apple maggot flies and many pests.
Drosophila suzukii, commonly called the spotted wing drosophila or SWD, is a fruit fly. D. suzukii , originally from southeast Asia, is becoming a major pest species in America and Europe, because it infests fruit early during the ripening stage, in contrast with other Drosophila species that infest only rotting fruit.
The halteres are club-shaped organs, used to balance the insect in flight, consisting of a proximal portion connected to a mechano-sensory organ. The homology between the wings and halteres is demonstrated by the four-winged mutant of the fruit fly Drosophila melanogaster. The development of the halteres varies according to the systematic group ...
An adult fruit fly is a strong flier that's been known to travel 30 miles in search of food and sites to lay eggs, giving it the ability to infest new areas quickly, according to the food and ...
The concept of wild type is useful in some experimental organisms such as fruit flies Drosophila melanogaster, in which the standard phenotypes for features such as eye color or wing shape are known to be altered by particular mutations that produce distinctive phenotypes, such as "white eyes" or "vestigial wings".
The majority of insects have two pairs of wings. Flies possess only one set of lift-generating wings and one set of halteres. The order name for flies, "Diptera", literally means "two wings", but there is another order of insect which has evolved flight with only two wings: strepsipterans, or stylops; [2] they are the only other organisms that possess two wings and two halteres.
