Family Muscidae and its members

Family Muscidae belongs to the order Diptera, meaning two-winged flies. This family includes a large number of species that are commonly known as house flies, stable flies, and face flies. They are important in veterinary medicine because they are vectors of various diseases.

House flies

House flies (Musca domestica) are one of the most common species in the family Muscidae. They are found throughout the world and are often considered a nuisance because they feed on garbage and other decaying organic matter. House flies are responsible for the spread of diseases such as typhoid fever, cholera, and dysentery.

House flies have a gray body with four black stripes on the thorax. They have large compound eyes that are red-colored with yellow margins. House flies have a proboscis that is used for feeding on liquids.

Other members of the family Muscidae

Other members of the family Muscidae include stable flies (Stomoxys calcitrans), face flies (Musca autumnalis), and horn flies (Haematobia irritans).

Stable flies are similar in appearance to house flies but have a more pointed proboscis that is used for biting. They are often found around livestock and can transmit diseases such as equine infectious anemia.

Face flies are slightly larger than house flies and have a distinctive behavior of feeding on the secretions of the eyes and nose of cattle. They are responsible for the spread of diseases such as pink eye in cattle.

Horn flies are small flies that are found on cattle. They feed on the blood of their host and can cause significant economic losses to the cattle industry.

Therefore, out of the given options, the only member of the family Muscidae is the house fly (option B).
