The male and the female horse flies are entirely distinct from each other in their behavior and habits. The females are more aggressive than the males. They prefer feeding on the blood of the prey. The male horsefly, on the other hand, is comparatively peaceful and harmless. They usually act as the pollinators and the pollen collectors. The process of tracing and locating the prey is a fascinating phenomenon. To catch the prey, they move after the dark objects in motion, and the carbon dioxide discharged from their bodies. To reach the victim, they follow the same pattern as that of the mosquitoes. The chemical and the visual cues both are helpful in figuring out where is the host. When the host releases the carbon dioxide, the horse fly can find him from a larger distance. When the host is closer, it is easier for the horse fly to find it with the help of movements, colors, and shape.
