Wait until you experience deer flies
Understanding the Two Flies
Deer Flies
Deer flies belong to the genus
Chrysops. They are relatively small, usually ranging from
6 to 10 millimeters in length. Despite their small size, they are fast, persistent, and extremely annoying to humans. Deer flies are often found in wooded areas, swamps, and near streams or lakes, where they thrive in humid, shaded conditions.
What sets deer flies apart is their tendency to target the upper parts of the body. They often bite around the head, neck, and shoulders, making them particularly bothersome for hikers, campers, and hunters.
Horse Flies
Horse flies are the larger relatives in the
Tabanidae family. Ranging from
10 to 30 millimeters, they are among the biggest biting flies encountered by humans and livestock. Their size gives them a powerful flying ability, allowing them to chase hosts over short distances.
Unlike deer flies, horse flies are commonly found in open environments such as fields, farms, wetlands, and areas near livestock. Farmers often view them as a major nuisance because they harass horses, cattle, and other animals, causing stress and reducing productivity.
Deer Fly Bites
Deer fly bites are sharp and painful, though usually less severe than horse fly bites. They often feel like a quick pinch followed by a burning sensation. The bite area may develop into a small, red bump or welt. Itching and mild swelling are common, and in some people, the bites may blister. Deer fly bites are irritating but usually fade within a few days without complications.
Horse Fly Bites
Horse fly bites are
far more painful because of their larger mouthparts and the deeper wound they leave behind. Victims often describe the bite as a stabbing or cutting pain. Within minutes, the site may swell into a large, raised welt that can stay inflamed for several days. Burning, redness, and persistent itching are common. Because horse fly bites cause larger wounds, they are more likely to bleed and become infected if scratched.
