1. What Exactly Are Deer Flies?

What are deer flies? Deer flies are blood-sucking insects that target humans and animals, with females needing blood for egg production. Males feed on pollen and nectar. A deer fly bite can be painful, described by some as akin to a bee sting, and the fly’s saliva often causes itching and discomfort. Some individuals may experience severe allergic reactions.

Compared to houseflies, adult deer flies are larger, typically ranging from 0.25 to 1.25 inches in length. A key deer fly identification lies in their prominent eyes and the purple or green bands on their blue or yellow-green wings. Their mouthparts are also noticeable, extending downward and projecting forward. Their fan-shaped wings enable rapid long-distance flight.

Deer flies thrive in wooded, wetland, and moist environments because their larvae require aquatic habitats. These larvae pupate and feed on tiny insects found near muddy water edges. Natural predators of deer flies include birds, dragonflies, hornets, wasps, spiders, toads, and frogs.

Deer flies and horseflies belong to the Tabanidae family, also known as tabanids. Globally, there are over 4,000 species of deer flies and horseflies, with approximately 335 in the United States. Deer flies comprise over 110 of these species, while horseflies account for more than 160. Indiana is home to a significant portion of these species.

2. What Is The Deer Fly Life Cycle?

What is the deer fly life cycle? The deer fly life cycle consists of four stages: egg, larva, pupa, and adult. Each stage occurs in specific environments, with the larval stage requiring aquatic or moist conditions. Understanding this cycle helps in implementing targeted control measures.

2.1. Egg Stage

Deer flies lay eggs in masses ranging from 100 to 1,000 at a time. These eggs are deposited in layers on vertical surfaces such as aquatic vegetation, sticks, foliage, and rocks directly above water or damp ground, supporting the larvae. Typically, the eggs are covered with a chalk-like or shiny substance that protects them from moisture. Initially, the eggs have a creamy white appearance, which darkens to gray or black as they mature. These cylinder-shaped eggs are quite small, measuring between 1 and 2.5 millimeters long. After about a week, the eggs hatch, and the larvae drop to the wet ground below.

2.2. Larval Stage

Deer fly larvae live in aquatic or semi-aquatic habitats such as marshes, ponds, and wet soil. These larvae are carnivorous, feeding on small insects, worms, and other organic matter found in their environment. The larval stage can last from several months to over a year, during which the larvae undergo multiple molts as they grow.

2.3. Pupal Stage

Once the larvae are fully grown, they transform into pupae. The pupal stage typically lasts a few weeks and occurs in drier soil near the larval habitat. During this stage, the pupae do not feed but undergo significant internal changes to develop into adult flies.

2.4. Adult Stage

Adult deer flies emerge from the pupal stage ready to mate and feed. Female deer flies require blood meals to produce eggs, while males feed on nectar and pollen. Adult deer flies are active during the daytime and are known for their persistent and annoying biting behavior.

3. Why Are Deer Flies So Persistent When They Bite?

Why are deer flies so persistent when they bite? Deer flies are persistent because they rely on blood meals for reproduction, and their bite mechanism is designed for efficiency. Their tenacity is driven by a biological imperative to ensure the survival of their species.

Deer flies are known for their relentless pursuit of hosts. Several factors contribute to their persistence:

Biological Need: Female deer flies need blood to develop their eggs. This biological imperative drives their persistent biting behavior.
Attraction to Movement and Carbon Dioxide: Deer flies are attracted to movement and the carbon dioxide exhaled by humans and animals, making them follow potential hosts relentlessly.
Vision: Deer flies have excellent vision and can spot moving targets from a distance, allowing them to track and pursue their prey effectively.
Bite Mechanism: Their mouthparts are designed to efficiently slice through skin, making it easier for them to obtain a blood meal quickly.
Annoying Behavior: Deer flies tend to hover and circle around their targets, adding to their annoying and persistent behavior.

4. Are There Specific Times When Deer Flies Are More Active?

Are there specific times when deer flies are more active? Deer flies are generally most active during the daytime, particularly in warm, sunny weather. Peak activity usually occurs in the late morning and early afternoon.

Deer flies exhibit seasonal and daily patterns of activity:

Seasonal Activity: Deer flies are most active during the warm months, typically from late spring to early fall. The exact timing can vary depending on the geographical location and weather conditions.
Daily Activity: Deer flies are diurnal, meaning they are active during the day. Their peak activity is usually in the late morning and early afternoon when the sun is highest.
Weather Conditions: Deer flies prefer warm, sunny weather with little to no wind. They are less active on cloudy, rainy, or windy days.
Habitat: Deer flies are commonly found in wooded areas, wetlands, and near bodies of water, so activity levels may be higher in these environments.
Host Availability: Deer flies are more active when their hosts, such as humans and animals, are present in their habitat.

5. What Makes A Deer Fly Bite So Painful?

What makes a deer fly bite so painful? The pain from a deer fly bite comes from their scissor-like mouthparts that slice through the skin and the irritants in their saliva. This combination results in immediate pain and prolonged itching.

Deer fly bites are known for being particularly painful due to several factors:

Mouthparts: Deer flies have scissor-like mouthparts called mandibles and maxillae. These sharp structures are used to slice through the skin to create a wound from which the fly can feed on blood.
Cutting Action: Unlike mosquitoes that have a proboscis to pierce the skin, deer flies cut into the skin, causing more tissue damage and immediate pain.
Saliva: Deer flies inject saliva into the wound to prevent blood from clotting. This saliva contains various compounds that can cause irritation, inflammation, and an allergic reaction in some individuals.
Nerve Stimulation: The cutting action and the components in the saliva stimulate nerve endings in the skin, resulting in a sharp, stinging pain.
Secondary Infection: The open wound created by the deer fly bite can become infected if not properly cleaned and cared for, leading to additional pain and discomfort.

6. How To Identify A Deer Fly Bite?

How to identify a deer fly bite? A deer fly bite typically appears as a raised, red bump with a surrounding area of redness and swelling. The bite is often painful and itchy, and it may bleed slightly due to the fly’s cutting mouthparts.

Identifying a deer fly bite involves recognizing its distinctive characteristics:

Immediate Pain: Deer fly bites are immediately painful due to the fly’s scissor-like mouthparts cutting into the skin.
Raised, Red Bump: The bite typically appears as a raised, red bump on the skin, similar to other insect bites.
Surrounding Redness: The area around the bite may become red and inflamed due to the fly’s saliva and the body’s immune response.
Swelling: Swelling may occur around the bite area, especially in individuals who are more sensitive to insect bites.
Itchiness: Deer fly bites are often very itchy, and scratching the bite can exacerbate the irritation and increase the risk of infection.
Bleeding: The bite may bleed slightly due to the cutting action of the fly’s mouthparts.
