Sep 05, · The adult housefly that emerges from the pupa lives from two weeks to a month in the wild, or longer in laboratory conditions. One can say that the fly once out of the pupa shell stops growing. The small flies you see are no different from the bigger ones. The adult housefly is dull gray with dirty-yellowish areas on the abdomen and longitudinal lines on the thorax. Body size ranges from about 5 to 7 mm ( to inch), and the conspicuous compound eyes have approximately 4, facets.
Life Expectancy of House Flies Houseflies pass through four distinct stages: egg, larva, pupa and adult. The life expectancy of a housefly is generally 15 to 30 days and depends upon temperature and living conditions. Flies dwelling in warm homes and laboratories develop faster and live longer than their counterparts in the wild. An adult housefly is about 6 to 7mm long with a wingspan of 13 to 15mm. A female housefly is larger than the male housefly. A male housefly has longer legs. More size variation is seen in female house flies.
