Antique engraved illustration of the housefly (Musca domestica), parts of housefly body. Vintage illustration of the housefly (Musca domestica). Old engraved picture of the housefly body (Musca domestica). Adult houseflies are usually 6 to 7 mm (1 4 to 9 32 in) long with a wingspan of 13 to 15 mm (1 2 to 19 32 in). The females tend to be larger winged than males, while males have relatively longer legs. Females tend to vary more in size and there is geographic variation with larger individuals in higher latitudes. The head is strongly convex in front and flat and slightly conical behind. The pair of large compound eyes almost touch in the male, but are more widely separated in the female. They have three simple eyes (ocelli) and a pair of short antennae. Houseflies process visual information around seven times more quickly than humans, enabling them to identify and avoid attempts to catch or swat them, since they effectively see the human's movements in slow motion with their higher flicker fusion rate.
