1. Understanding the Biting Fly: An Overview
1.1 What are Biting Flies?
Biting flies are a diverse group of insects that feed on the blood of humans and animals. Unlike flies that feed on nectar or decaying matter, biting flies require blood to complete their reproductive cycle. These flies are equipped with specialized mouthparts designed to pierce the skin and extract blood.
1.2 Types of Biting Flies
There are numerous species of biting flies, each with its own characteristics and behaviors. Some of the most common types include:
- Mosquitoes (Culicidae)
- Deer Flies and Horse Flies (Tabanidae)
- Stable Flies (Stomoxys calcitrans)
- Black Flies (Simuliidae)
- Biting Midges (Ceratopogonidae)
- Sand Flies (Psychodidae)
1.3 The Role of Blood in Reproduction
Female biting flies need blood to produce eggs. The proteins and nutrients in blood are essential for egg development. After a female fly takes a blood meal, she can lay a batch of eggs. This process may be repeated several times throughout her life, depending on the species and environmental conditions.
2. The Science Behind the Bite: Why You?
2.1 Attractants: What Draws Flies In?
Biting flies use a combination of sensory cues to locate their hosts. These cues include chemical signals, visual stimuli, and environmental factors. Understanding these attractants can help you take steps to minimize your appeal to these pests.
2.2 Carbon Dioxide and Breath
Carbon dioxide (CO2) is a primary attractant for many biting flies, especially mosquitoes. Flies have specialized receptors that can detect even small changes in CO2 concentration in the air. When you exhale, you release CO2, which signals to the flies that a potential blood source is nearby.
2.3 Body Odor and Perspiration
Body odor and perspiration contain a complex mixture of chemicals, including lactic acid, ammonia, and fatty acids. These compounds can be highly attractive to certain species of biting flies. Individuals with higher concentrations of these chemicals may be more likely to be bitten.
2.4 Visual Cues: Color and Movement
Visual cues also play a role in attracting biting flies. Dark colors, such as black and navy blue, tend to attract flies more than light colors. Movement can also make you a more visible target. Flies are more likely to notice and approach a moving object than a stationary one.
2.5 Heat and Moisture
Heat and moisture are additional factors that can attract biting flies. Flies are sensitive to temperature changes and are drawn to warm-blooded animals. Moisture, such as perspiration, can also increase your attractiveness to these pests.
Here’s a summary table of the attractants:
| Attractant | Description |
|---|---|
| Carbon Dioxide | Released during exhalation; a primary attractant for many biting flies. |
| Body Odor | Contains chemicals like lactic acid and ammonia that attract flies. |
| Perspiration | Contains fatty acids and other compounds that are attractive to flies. |
| Dark Colors | Dark clothing tends to attract more flies than light-colored clothing. |
| Movement | Flies are more likely to target moving objects. |
| Heat | Warm-blooded animals are attractive to flies due to their body heat. |
| Moisture | Perspiration and humidity can increase attractiveness to flies. |
3. Identifying Common Biting Flies
3.1 Mosquitoes (Culicidae)
Mosquitoes are perhaps the most well-known biting flies. They are slender-bodied insects with long legs and scaled wings. Female mosquitoes feed on blood, while males feed on nectar. Mosquitoes are vectors for numerous diseases, including malaria, Zika virus, and West Nile virus.
3.2 Deer Flies and Horse Flies (Tabanidae)
Deer flies and horse flies are larger than mosquitoes and have stout bodies. They are known for their painful bites, which are caused by their scissor-like mouthparts that cut into the skin.

4. Health Risks Associated with Biting Fly Bites
4.1 Allergic Reactions
Biting fly saliva contains anticoagulants and other substances that can trigger allergic reactions in sensitive individuals. These reactions can range from mild itching and swelling to severe, life-threatening anaphylaxis.
4.2 Disease Transmission
Many biting flies are vectors for diseases that can affect humans and animals. These diseases can be transmitted through the fly’s saliva during the blood-feeding process.
4.3 Tularemia
Tularemia, also known as rabbit fever, is a bacterial disease that can be transmitted by deer flies. Symptoms include fever, skin ulcers, and swollen lymph nodes.
4.4 Leishmaniasis
Leishmaniasis is a parasitic disease transmitted by sand flies. It can cause skin lesions, fever, and organ damage.
4.5 Other Diseases
Biting flies can also transmit other diseases, including:
- West Nile Virus
- Zika Virus
- Malaria
- Dengue Fever
- Blue Tongue Virus (in livestock)
