A Guide to Different Types of Flies: An Overview of Common Species


Flies are a common sight in our daily lives, buzzing around our homes, gardens, and outdoor spaces. While they may often be considered a nuisance, it's fascinating to explore the diverse world of these insects. From their physical characteristics to their habits and behavior, flies come in various shapes and sizes. In this article, we will provide an overview of some of the most common fly species, shedding light on their unique traits and answering frequently asked questions about these intriguing creatures.

1. House Fly (Musca domestica):

The house fly is perhaps the most well-known species. With a dull gray color and reddish eyes, it can be found worldwide. House flies are attracted to human habitation and are known for spreading diseases by contaminating food and surfaces.

2. Fruit Fly (Drosophila melanogaster):

These tiny flies, often found in our kitchens, are attracted to ripe fruits and vegetables. Fruit flies have a yellowish-brown body and red eyes. They are harmless but can be a nuisance due to their rapid reproduction rate.

3. Blow Fly (Calliphoridae):

Blow flies are commonly found in decaying matter and carcasses. Their metallic, shiny appearance distinguishes them from other fly species. These flies play a vital role in forensic entomology, helping investigators determine the time of death at crime scenes.

4. Horse Fly (Tabanidae):

Horse flies are known for their painful bites, which can be quite bothersome to both humans and animals. With large compound eyes and a strong, scissor-like mouthpart, horse flies feed on blood. They are typically found near water bodies and prefer warm climates.

5. Mosquito (Culicidae):

Mosquitoes are infamous for their blood-sucking habits and their ability to transmit diseases such as malaria, dengue fever, and Zika virus. Only female mosquitoes feed on blood, while males primarily consume nectar. Mosquitoes are attracted to stagnant water for breeding.

6. Crane Fly (Tipulidae):

Often mistaken for large mosquitoes, crane flies have long, fragile legs and a slender body. Contrary to popular belief, crane flies are harmless and do not bite humans or animals. They are attracted to moist environments and are often seen in gardens and fields.

7. Cluster Fly (Pollenia rudis):

Cluster flies are notorious for seeking shelter indoors during the winter months. These flies have a dark gray thorax and abdomen covered in golden hairs. They are harmless but can become a nuisance when they populate homes in large numbers.

8. Stable Fly (Stomoxys calcitrans):

Stable flies resemble house flies but have a painful bite, commonly affecting livestock and horses. These flies breed in decaying organic matter and are often found in agricultural areas. Stable fly bites can cause discomfort and can transmit diseases.

9. Greenbottle Fly (Lucilia spp.):

Greenbottle flies are vibrant metallic blue or green in color. They are attracted to decaying organic matter, including carcasses and garbage. Greenbottle flies play an essential role in forensic investigations, aiding in determining the time of death.

10. Black Fly (Simuliidae):

Black flies are notorious for their painful bites, often causing swollen and itchy reactions in humans. They are commonly found near rivers and streams, where they breed and lay their eggs. Black flies are significant pests for outdoor enthusiasts, particularly during the warmer months.

1. Are flies harmful to humans?
While most fly species are harmless, some can spread diseases or cause painful bites. It is essential to maintain good hygiene and take preventive measures to keep flies away from food and living spaces.

2. How long do flies live?
The lifespan of flies varies depending on the species. House flies, for example, typically live for 15 to 30 days, while fruit flies have a shorter lifespan of only a few days.

3. How can I get rid of flies in my home?
To get rid of flies indoors, it is important to eliminate their breeding grounds by keeping garbage tightly sealed and maintaining clean living spaces. Additionally, using fly traps or insecticides can help control their population.

4. Can flies transmit diseases?
Certain fly species, such as house flies and mosquitoes, can transmit diseases by contaminating food or through their bites. It is crucial to take precautions to minimize contact with flies and maintain a hygienic environment.

5. Why are flies attracted to certain areas?
Flies are attracted to areas with decaying organic matter, such as garbage, rotting food, or animal waste. They are also drawn to warm and moist environments, making kitchens and outdoor spaces appealing to them.

6. Do all fly species bite?
No, not all fly species bite. Only specific species, such as mosquitoes, horse flies, and stable flies, have mouthparts designed for piercing the skin and feeding on blood.

7. Can flies be beneficial?
Despite their reputation as pests, flies play a crucial role in ecosystems. Some species aid in pollination, while others assist in decomposition and nutrient recycling. Additionally, certain fly larvae are used in medical research and forensic investigations.

8. How do flies find food?
Flies have specialized sensory organs that allow them to detect odors associated with decaying organic matter. They use their compound eyes and antennae to navigate and locate food sources.

9. Why do flies buzz around our heads?
Flies buzz around humans and animals as a means of communication and to locate potential food sources. They are attracted to the carbon dioxide we exhale, body heat, and sweat, which they perceive as potential food.

10. Can flies be controlled without using chemicals?
Yes, flies can be controlled through various non-chemical methods. These include using fly screens on windows and doors, maintaining cleanliness, and using natural repellents like fly traps or essential oils.


Flies are a diverse group of insects that have adapted to various environments and play unique roles in ecosystems. While some species can be annoying or harmful, others contribute to important ecological processes. By understanding the characteristics and habits of different fly species, we can better coexist with these fascinating creatures while taking necessary precautions to minimize their negative impacts on our lives.
