Flies are insects of the order Diptera, the name being derived from the Greek. Flies undergo complete metamorphosis; the eggs are often laid on the larval food-source and the larvae, which lack true limbs, develop in a protected environment, often inside their food source.
Other species like Metopia argyrocephala are ovoviviparous, opportunistically depositing hatched or hatching maggots instead of eggs on carrion, dung, decaying material, or open wounds of mammals. The pupa is a tough capsule from which the adult emerges when ready to do so; flies mostly have short lives as adults.
Flies do not typically live in groups. They are often nomadic, following food sources. They frequently choose to make habitats in areas replete with trash and dirt. They feed on decaying matter, trash and fecal matter.
House flies are not only nuisance pests while buzzing around homes, but they are potential disease carriers. House flies have short lifespans, but they can quickly reproduce in large numbers, leading to large house fly populations if not identified and effectively controlled.
Adult houseflies are diurnal and rest at night. 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.
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.[

The most common sign of a house fly infestation is the presence of the flies, themselves. Larvae may also be seen crawling out of their breeding material as they pupate. Along with seeing house flies, people may hear them around the home. House flies produce a buzzing sounds which is a result of their two wings beating together.
