Forty-eight hours after emergence as an adult, the female commences egg laying. During her adult life of 1-3 months she is capable of producing 4-5 batches of 100-150 eggs (1mm in length).
Those are laid in moist decaying matter such as household refuse, compost or dung. The eggs hatch in 8-48 giving larvae.
In the summer larval development may be completed within a few days, but in winter this process may take more than a month. Depending upon conditions, adults emerge 3 days to 4 weeks later. The full cycle is generally completed between one and 4 weeks, depending upon temperature. Under temperate conditions as many as 12 generations of flies may breed in one season.
Areas where found:
Common Houseflies (M. domestica) are ubiquitous insects, with a flight range of at least 8 kilometers. They are highly active indoors. In colder climates breeding generally ceases before winter, whereupon the insects overwinter either as pupae or adults. However, in warm environments houseflies remain active and reproduce throughout the year.
Importance as a pest:
Houseflies can transmit intestinal worms, or their eggs, and are potential vectors of diseases such as dysentery, gastroenteritis, typhoid, cholera and tuberculosis. They will frequent and feed indiscriminately on any liquefiable solid food, which may equally be moist, putrefying material or food stored for human consumption. Flies liquefy food by regurgitating digestive juices and their stomach contents on to the food substance. This ‘liquid’ is then drawn up by the suctorial mouthparts and in so doing the insects pick up pathogenic organisms, which may collect on their bodies to be transferred on contact with other surfaces or survive passage through the gut to be depos
