A fly has two compound eyes and each eye is made up between 3,000 and 6,000 simple eyes.  They can be opportunistic blood feeders.  Sexual differentiation is controlled, as in other insects, by an ancient developmental switch, doublesex, which is regulated by the transformer protein in many different insects. Each eye contains 4000 lenses that enable visualization of different pictures at the same time. , The mouthparts are specially adapted for a liquid diet; the mandibles and maxillae are reduced and not functional, and the other mouthparts form a retractable, flexible proboscis with an enlarged, fleshy tip, the labellum.  The housefly's superfamily, Muscoidea, is most closely related to the Oestroidea (blow flies, flesh flies and allies), and more distantly to the Hippoboscoidea (louse flies, bat flies and allies). In fact, an insect can live for several days without a head, assuming it does not lose a lethal amount of hemolymph, the insect equivalent of blood, upon decapitation. Moths, for example have a completely different type of compound eye. :96 Because the somatic tissue of the housefly consists of long-lived postmitotic cells, it can be used as an informative model system for understanding cumulative age-related cellular alterations.  The introduction of dung beetles to churn up the surface of a manure heap and render it unsuitable for breeding is another approach. CEO Compensation and America's Growing Economic Divide. They alternate between breeding and feeding in dirty places with feeding on human foods, during which process they soften the food with saliva and deposit their feces, creating a health hazard.

This is all down to … , Houseflies can fly for several kilometers from their breeding places, carrying a wide variety of organisms on their hairs, mouthparts, vomitus, and feces. The male then reverses onto her abdomen and the female pushes her ovipositor into his genital opening; copulation, with sperm transfer, lasts for several minutes. They can carry pathogens on their bodies and in their feces, contaminate food, and contribute to the transfer of food-borne illnesses, while, in numbers, they can be physically annoying.  At the end of each leg is a pair of claws, and below them are two adhesive pads, pulvilli, enabling the housefly to walk up smooth walls and ceilings using Van der Waals forces. It is the most common fly species found in houses. Authors sometimes choose the housefly to speak of the brevity of life, as in William Blake's 1794 poem "The Fly", which deals with mortality subject to uncontrollable circumstances. The structure and function of a fly's eye are completely different from ours, and so they see shapes, motion and color differently. A house fly infestation can be annoying at best and dangerous at worst, but with the correct sanitation prevention measures and right extermination methods, the problem is easily fixable.

They also have have 3 other regular eyes that are not for seeing. This allows the fly to see a far wider range, as well as detect and react to movement at a quicker pace than species with simple eyes. , When metamorphosis is complete, the adult housefly emerges from the pupa.  Houseflies do not serve as a secondary host or act as a reservoir of any bacteria of medical or veterinary importance, but they do serve as mechanical vectors to over 100 pathogens, such as those causing typhoid, cholera, salmonellosis, bacillary dysentery, tuberculosis, anthrax, ophthalmia, and pyogenic cocci, making them especially problematic in hospitals and during outbreaks of certain diseases. Houseflies have a small number of chromosomes, haploid 6 or diploid 12. "The etymology of Beelzebul has proceeded in several directions. male and female heterogamy, haplodiploidy, environmental factors), the way sex is determined is usually fixed within a species.

In cooler climates, some houseflies hibernate in winter, choosing to do so in cracks and crevices, gaps in woodwork, and the folds of curtains. , The housefly was first described as Musca domestica in 1758 based on the common European specimens by the Swedish botanist and zoologist Carl Linnaeus in his Systema naturae and continues to be classified under that name. , The thorax is a shade of gray, sometimes even black, with four dark, longitudinal bands of even width on the dorsal surface. Keeping garbage in lidded containers and collecting it regularly and frequently, prevents any eggs laid from developing into adults.

Houseflies land on a ceiling by flying straight towards it; just before landing, they make a half roll and point all six legs at the surface, absorbing the shock with the front legs and sticking a moment later with the other four. House flies are covered with small hairs that serve as taste organs. Affected females tend to be more attractive to males, but the fungus-host interactions have not been fully understood. Houseflies can see behind them. After infection, the fungal hyphae grow throughout the body, killing the housefly in about five days. Horse fly, any member of the insect family Tabanidae (order Diptera), but more specifically any member of the genus Tabanus. Characteristically, the medial vein (M1+2 or fourth long vein) shows a sharp upward bend. The belief that housefly control was the key to disease control continued, with extensive use of insecticidal spraying well until the mid-1950s, declining only after the introduction of Salk's vaccine. After two to five days of development, these metamorphose into reddish-brown pupae, about 8 millimetres (3⁄8 inch) long.  Usually, too few bacteria are on the external surface of the houseflies (except perhaps for Shigella) to cause infection, so the main routes to human infection are through the housefly's regurgitation and defecation. 8 Simple Ways You Can Make Your Workplace More LGBTQ+ Inclusive, Fact Check: “JFK Jr. Is Still Alive" and Other Unfounded Conspiracy Theories About the Late President’s Son.

Adults are gray to black, with four dark, longitudinal lines on the thorax, slightly hairy bodies, and a single pair of membranous wings. Cattle, goat, and horse manures produce fewer, smaller pupae, while fully composted swine manure, with a water content under 40%, produces none at all. , During the Second World War, the Japanese worked on entomological warfare techniques under ShirÅ Ishii. The pair of large compound eyes almost touch in the male, but are more widely separated in the female. Their eyes are red, and females are generally a bit larger than males. , Insecticides can be used. If inside a building after dark, they tend to congregate on ceilings, beams, and overhead wires, while out of doors, they crawl into foliage or long grass, or rest in shrubs and trees or on wires. So apposition-eyes have some real advantages, but they’re not the only kind of compound eye. , The life cycle can be completed in seven to 10 days under optimal conditions, but may take up to two months in adverse circumstances. For these reasons, they are considered pests. There is also a female-determining allele of transformer that is not sensitive to the negative regulation of Mdmd. Females normally mate only once and then reject further advances from males, while males mate multiple times.  Studies of tethered houseflies have helped in the understanding of insect vision, sensory perception, and flight control. The pupal case is cylindrical with rounded ends, about 1.2 mm (1⁄16 in) long, and formed from the last shed larval skin. This cuticular hydrocarbon is not released into the air and males sense it only on contact with females; it has found use as in pest control, for luring males to fly traps. Flies, such as the common housefly (Musca domestica) look at the world in quite a different way than humans do. , The larvae depend on warmth and sufficient moisture to develop; generally, the warmer the temperature, the faster they grow. Within a day, larvae (maggots) hatch from the eggs; they live and feed where they were laid. , Houseflies sometimes carry phoretic (nonparasitic) passengers, including mites such as Macrocheles muscaedomesticae and the pseudoscorpion Lamprochernes chyzeri. He climbs on to her thorax, and if she is receptive, a courtship period follows, in which the female vibrates her wings and the male strokes her head. It is present in the Arctic, as well as in the tropics, where it is abundant. Photo: cglade /Getty Images / iStockphoto 6 of 12 When flies lay eggs on food, white maggots hatch after a few days. Aerosols can be used in buildings to "zap" houseflies, but outside applications are only temporarily effective. Solutions include disposing of the attractants and using repellents to keep the flies away in the first place. Flies also have three simple eyes in between the compound eyes called ocelli.
