Which biting flies are known to attack humans?

• A. House flies
• B. Cluster flies
• C. Horse-flies, stable-flies, black-flies, and deer-flies
• D. Fruit flies

Answer: (C)

The choice identifying horse-flies, stable-flies, black-flies, and deer-flies as biting flies that attack humans is accurate because these insects possess the anatomical adaptations necessary to pierce the skin and feed on blood. Horse-flies and stable-flies, for instance, have sharp mouthparts that allow them to inflict pain when feeding. They are often found in agricultural settings and can be very aggressive in their pursuit of a blood meal. Black-flies, known for their biting behavior, can cause significant discomfort and, in some cases, transmit diseases. Deer-flies are similar to horse-flies and are particularly well-known for their biting habits in wooded or rural areas. In contrast, house flies and cluster flies primarily feed on decaying organic matter and do not bite humans. They may pose health risks as potential vectors for disease but do not engage in blood-feeding. Fruit flies are completely benign in this context; they are primarily associated with decaying fruit and do not possess the physical capability or behavior associated with biting humans. Thus, the correct answer highlights the specific types of insects recognized for their biting behavior and potential to affect human health directly through their feeding habits.
