True flies are insects of the order Diptera. The name is derived from the Greek di-= two, and ptera = wings. Most insects of this order have two wings (not counting the halteres, club-like limbs which are homologous to the second pair of wings found on insects of other orders). Wingless flies are found on some islands and other isolated places.
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. [2] Flightless fly models have been especially useful for the study of human neuromuscular diseases such as spinal muscular atrophy, spinobulbar muscular atrophy, myotonic dystrophy ...
They are flattened, spiderlike flies without eyes or wings, and as such bear very little resemblance to other Dipterans. These flies are seldom encountered by general collectors, as they almost never leave the bodies of their hosts. Both males and females take blood meals, thus qualifying as parasites. Most species are highly host-specific.
Alternatively flies of genus Melophagus are so adapted to parasitism that the adults never develop wings. Louse-flies without wings may appear like ticks, but the only stage of tick seen with three pairs of legs will be larvae these are much smaller than louse-flies.
The subphylum Hexapoda (from Greek for 'six legs') or hexapods comprises the largest clade of arthropods and includes most of the extant arthropod species. It includes the crown group class Insecta (true insects), as well as the much smaller clade Entognatha, which includes three classes of wingless arthropods that were once considered insects: Collembola (springtails), Protura (coneheads) and ...
D. melanogaster which carries the Cy allele (right), hence showing a characteristic phenotype of curly wings in adult flies [54] Genetic markers are commonly used in Drosophila research, for example within balancer chromosomes or P-element inserts, and most phenotypes are easily identifiable either with the naked eye or under a microscope. In ...
The wings of the fly are attached to two kinds of muscles, those used to power it and another set used for fine control. [49] Flies tend to fly in a straight line then make a rapid change in direction before continuing on a different straight path.
Hermetia illucens, the black soldier fly, is a common and widespread fly of the family Stratiomyidae. Since the late 20th century, H. illucens has increasingly been gaining attention because of its usefulness for recycling organic waste and generating animal feed.
