Body structure of the housefly
The body structure of the housefly (Musca domestica) is adapted to its specific lifestyle and diet. This small insect can grow up to 7.5 mm long, making it difficult to spot at first glance. Its body consists of three main parts: head, thorax and abdomen, the most characteristic of which is its dark grey abdomen with longitudinal stripes, which gives the housefly its specific appearance.
The eyes of the housefly provide it with an extraordinary 360° field of vision, which allows it to detect movement in its immediate surroundings. Another important part of the body is the licking mouthparts, which enable the fly to obtain liquid food. Key features of the housefly’s body are:
- Body length up to 7.5 mm
- Dark grey torso with longitudinal stripes
- Eyes with 360° field of vision
- Licking mouthparts
Thanks to these characteristics, Musca domestica is perfectly adapted to its environment and lifestyle.
Lifestyle and nutrition of the housefly
The housefly is extremely active during the day when temperatures are favourable for its lifestyle, preferring warm and humid environments. Its diet is varied, with adults feeding mainly on liquids, which they can easily extract thanks to their licking proboscis. Human food, organic waste and even animal excrement are valuable sources of nutrition for them. Houseflies often visit places where there is manure, which not only provides them with nutrients but also provides an excellent environment for the development of their larvae.
Housefly larvae have different food preferences to adults. The most optimal food for them is rotting organic matter, such as kitchen waste, rotting fruit or fertiliser. Such an environment is necessary for their proper growth and the transition to the next stages of development. The presence of the housefly in such a wide variety of places is related to its ability to adapt quickly to different conditions, making it one of the most widespread insects in the world.
Dangers associated with houseflies
The risks associated with the presence of houseflies are significant, especially in epidemiological terms. The housefly is known to transmit various diseases and parasites, which becomes particularly dangerous in conditions conducive to the rapid growth of this insect’s population. Thanks to their ability to detect movement and their wide field of vision, houseflies easily avoid threats, which makes it difficult to control them. One of the main threats is the fact that these flies carry pathogens from rotting organic matter, excrement and other contaminants on their legs and bodies.
As a result, the presence of houseflies can lead to the spread of diseases such as dysentery, salmonellosis and typhoid fever. In addition, houseflies can be carriers of parasites, such as nematode eggs, which increases the risk of infection for humans and animals.

Frequently asked questions
What does a housefly (Musca domestica) look like and how can you identify it?
A housefly can grow up to 7.5 mm long and has a body divided into the head, thorax and abdomen. It is typically dark grey with longitudinal stripes and has eyes that provide a 360° field of vision. It also has licking mouthparts adapted to liquid food.
What do adult houseflies eat, and how do they feed?
Adult houseflies feed mainly on liquids, using their licking proboscis to take up food. They often consume human food, organic waste and animal excrement.
What do housefly larvae eat and where do they develop?
Housefly larvae feed best on rotting organic matter such as kitchen waste, rotting fruit or fertiliser. They develop in environments rich in such material, including places where manure is present.
Why are houseflies considered dangerous to humans and animals?
Houseflies can carry pathogens from rotting organic matter, excrement and other contaminants on their legs and bodies. They may also carry parasites, increasing the risk of infection for both humans and animals.
What diseases can houseflies transmit?
Houseflies can spread diseases such as dysentery, salmonellosis and typhoid fever. This risk increases where conditions allow their populations to grow quickly.
Where are houseflies most commonly found and what conditions attract them?
Houseflies are most active during the day and prefer warm, humid environments. They commonly visit areas with human food, organic waste, manure and animal excrement, which provide both nutrition and suitable conditions for development.
