Deer flies and their close relatives, the horse fly, feed on the blood of humans and other animals. They are active during the day and are common in the summer months, preferring damp, wooded, and wetland environment. Deer flies look similar to house flies, but have brightly colored eye parts and striped abdomen. They rely on color, movement or carbon dioxide from breath to find a suitable host. Once bare skin is found, they use razor-sharp mandibles (mouthparts) to cut the skin and feed on the blood. Deer and horse flies are a real nuisance as their bite is painful and leaves a nasty mark.
