The fly is a small insect with large eyes, a pair of transparent wings, six legs, two small antennas and gray-black body with dark chest and bright tail. Its role in the ecosystem is to decompose organic waste of digestible substances and it deals with this function successfully.

Fly belongs to a large section of insects called dipterous (Diptera). The most mosquitoes belong to this section too. Typical for these insects is that instead of four wings, as all the others, Diptera (lit. two wings) has only two functional wings and the other two are only for the balance of the movement.

Housefly

The fly can be seen most often in areas related to people, their animals and activities. This is especially for the housefly (Musca domestica). Over 90% of the flies that you find in the room, at home or in the public houses are representatives of exactly this kind.

The appearance of the fly, as well as its size vary depending on the type. The fruit flies and the channel flies from the Flies family are only a few millimeters long, while the housefly has a total body size from half to one centimeter.

The housefly is often accused of biting, but it is unfair to her. In practice, it has no organs that can bite or sting the skin, not even something to chew a solid food with. Responsible for these bites are another kind similar to it flies such as the horsefly, but most commonly the dog fly (Stomoxys calcitrans). The dog or the cattle-shed fly is very much similar to the housefly, but is sucking blood from mammals. You will recognize it on that it is small.

The fly, like the most insects do not breathe through the head. Air enters through openings in the body and through small tubes reaches the abdomen or the chest. There, the oxygen is collected in the main trachea, leading to an organ with liquid. The liquid dissolves and spreads it throughout the body.

The eyes of the fly are essential for its survival. They are complex, as in the upper part there are two large compound eyes, and below them there are three simple. The complex eye is composed of up to 6000 simple, which are like thousands of small screens transmitting separate information. This structure helps to detect any movements around, regardless of their location and speed. In this way the fly manages to see the blow and take off even while you are reaching for it.
