Species domestica (House Fly)
Explanation of Names
Musca domestica Linnaeus 1758
adult body 6-7 mm; females usually larger than males; larva 3-12 mm; pupa to 8 mm
cosmopolitan, of Eurasian origin
around homes, poultry & dairy farms, stables, garbage dumps, and other sources of rotting plant or animal matter; adults are inactive at night, often resting on ceilings in buildings, or on vegetation outdoors
spring through fall
adults feed on fresh and fermenting/rotting food, and garbage; adult mouthparts allow ingestion of liquid food only; solid materials are liquified by means of regurgitated saliva
larvae feed on moist material rich in organic matter where eggs were laid: manure, rotting plant or animal tissue, garbage
Life Cycle
Overwinters as larva or pupa under manure piles or in other protected locations. During summer, the life cycle can be completed in 7-10 days, and up to 12 generations may occur in one summer. Eggs are laid singly but pile up in small masses. Each female fly can lay up to 500 eggs in several batches of 75-150 eggs, each over a 3-4 day period. The larvae emerge within 8-20 hours and develop through 3 instars. Full-grown larvae crawl up to 15 m to a dried cool place and pupate. Adults usually live 15-25 days.(1)
>100 pathogens associated with the house fly may cause disease in humans and animals; pathogens are picked up by flies from garbage, sewage and other sources of filth, and transferred to human and animal food on fly mouthparts, other contaminated body parts, or through their vomitus/feces(1)

Muscina stabulans (False Stable Fly) has a yellow-tipped scutellum, and its M1+2 vein is gently curved (not sharply bent) and doesn't come close to touching vein R4+5 at the wing margin (see images and info for Muscina stabulans)
Stomoxys calcitrans (Stable Fly) has a different pattern on thorax and abdomen, biting mouthparts, and its M1+2 vein is not sharply bent (see dorsal view and ventral view of both species)
Some Calliphoridae (Blow Flies) and Sarcophagidae (Flesh Flies) have wings with a "scimitar-shaped" cell R5, but lack 4 stripes on the thorax and/or an ovoid frontal stripe that occupies more than half the distance between the eyes
