House Fly - Musca domestica

Order: Diptera  Family: Muscidae  Subfamily: Muscinae  Tribe: Muscini  Genus: Musca
Species: M. domestica

The housefly (also house fly, house-fly or common housefly), Musca domestica, is the most common of all flies found in homes, and indeed one of the most widely distributed insects, found all over the world; it is often considered a pest that can carry serious diseases.

The adults are 8–12 mm long. Their thorax is gray, with four longitudinal dark lines on the back. The underside of their abdomen is yellow, and their whole body is covered with hair-like projections. The females are slightly larger than the males, and have a much larger space between their red compound eyes.

Like most Diptera (meaning "two-winged"), houseflies have only one pair of wings; the hind pair is reduced to small halteres that aid in flight stability. Characteristically, the media vein (M1+2 or fourth long vein of the wing) shows a sharp upward bend.

Life cycle

Each female fly can lay approximately 500 eggs in several batches of about 75 to 150. The eggs are white and are about 1.2 mm in length. Within a day, larvae (maggots) hatch from the eggs; they live and feed in (usually dead and decaying) organic material, such as garbage or faeces. They are pale-whitish, 3–9 mm long, thinner at the mouth end, and have no legs. They live at least one week. At the end of their third instar, the maggots crawl to a dry cool place and transform into pupae, colored reddish or brown and about 8 mm long. The adult flies then emerge from the pupae. (This whole cycle is known as complete metamorphosis.) The adults live from two weeks to a month in the wild, or longer in benign laboratory conditions. After having emerged from the pupae, the flies cease to grow; small flies are not young flies, but are indeed the result of getting insufficient food during the larval stage.

Some 36 hours after having emerged from the pupa, the female is receptive for mating. The male mounts her from behind to inject sperm. Copulation takes between a few seconds to a couple of minutes. Normally the female mates only once, storing the sperm to use it repeatedly for laying several sets of eggs. Males are territorial: they will defend a certain territory against other males and will attempt to mount any females that enter that territory.

The flies depend on warm temperatures; generally, the warmer the temperature the faster the flies will develop. In winter, most of them survive in the larval or the pupa stage in some protected warm location.

Behavior

Houseflies can take in only liquid foods. They spit out saliva on solid foods to predigest it, and then suck it back in. They also regurgitate partly digested matter and pass it again to the abdomen.

The flies can walk on vertical planes, and can even hang upside-down from ceilings. This is accomplished with the surface tension of liquids secreted by glands near their feet. When they are not flying, flies continually preen themselves to aid in digestion and remove excess excrement.

Flies have an extremely evolved evasion reaction which helps to ensure their survival. It is possible to confuse a fly's evasion system by swatting it with two objects simultaneously from different directions. The holes in a fly swatter minimize the air current that warns the fly of being hit, whilst reducing air resistance and increasing speed of the swat.

In 2008 it was discovered that a fly anticipates the approach of a threat, calculating the angle of attack, and alters its stance ready to make the most appropriate getaway. This evasive action, which allows the fly to jump away in the opposite direction, takes place within 200 ms.

Houseflies release a pheromone called muscalure that serves both aggregation and sexual attraction purposes.
