There are many families of flies all over the world. Although basically the fly’s life cycle can range from a few days to a number years depending on the species and specific conditions, all flies have to undergo a complete four-stage life cycle that consists of egg, larva, pupa and adult stages.
In the wild, the adult housefly can live up to one month. The fruit fly can also live for approximately 30 days after reaching adulthood. Flies survive longest during warmer temperatures and the ideal temperatures—between 75 and 80 degrees—are those found in most homes in North America.
