Horseflies, also called the green-headed monsters, are small flying insects. Female horseflies feed on blood to reproduce. Like mosquitoes, female horse flies require a protein meal to produce eggs.
Like mosquitoes, horseflies have distinct mouthparts to feed on blood. The mouthparts of horse flies include:
- Scissor-shaped jaw to tear the skin
- Small hooks to help the horsefly lock in to suck better
However, unlike mosquitoes, which puncture and suck blood from their victim’s skin, horseflies tear the victim’s flesh. After using small hooks to lock in, the horse fly sucks blood from the skin. Thus, the saliva injected while biting causes a sharp burning sensation.
The saliva in the skin may also cause inflammation, itchiness, or bruise, around the site.
In some rare cases, a horsefly bite can trigger an allergic reaction, which includes:
- Abdominal pain or vomiting
- Chest pain
- Difficulty swallowing
- Difficulty breathing
- Face or mouth swelling
- Fainting or lightheadedness
- Rash or skin flushing
