Black flies and horse flies are both biting insects, but they have some key differences. Black flies are smaller and usually black or dark in color, while horse flies are larger and can be various colors. Black flies are known for their painful bites and are more likely to be found near running water, while horse flies are more commonly found in open fields and wooded areas. Additionally, black flies are active during the day, while horse flies are more active in the late afternoon and early evening.
