Description of the fly

Dimensions of these insects are small – 1-2 cm. Moreover, their body is divided into three parts, densely covered with hairs: head, abdomen and chest. On the head are huge faceted eyes and proboscis (it can be of different types, which depends on the type of insect). The thoracic department is rather small, covered with a shield from above. The abdominal department, on the contrary, is quite large, and even can stretch out.

In general, all flies are very similar in structure of the body. However, their color and size strongly depend on the type of insect, which, in turn, depends on the conditions and habitat. However, many representatives of this group of animals have a dark color. Often he pours green. Dark brown colors may also be observed.

The significance of flies in nature

In fact, these insects are important in nature. Otherwise it can not be, because they are very common, and they occur almost everywhere. And although they do not bring direct benefits, they are involved in the food chain, and this is very important. Flies are food for a huge amount of animals, and if they suddenly disappeared, the chain of nutrition would be broken. This can lead to serious consequences. For example, the disappearance of thousands of species of animals, so do not underestimate the importance of flies.

If we consider the role of these insects in the lives of people, then one can clearly say that harm brings much more than benefits. After all, they are the carriers of many infectious diseases, including those that lead to death. Although it is good to remember it is possible. For example, oparyashami – larvae of meat flies, previously wiped their wounds (now, by the way, they also sometimes use this method). However, the harm done by insects far outweighs the benefits.
