Flies

Fly

is a common name for Diptera insects belonging to the family of real flies (Muscclassae), living almost all over the Earth. The body (2-15 mm long) is dark, less often yellow or with metallic shine (blue or green), covered with hairs and bristles. About 5000 species are known. Widespread in all parts of the world. They feed on the juice of plants, decaying organic substances, manure, human feces; some are predators; some species are bloodsuckers.
Most lay eggs (up to 2 thousand eggs throughout life); Vegetation of larvae is less common. Larvae develop in decomposing organic substances, manure, less often in living tissues of plants and animals; in some species, the larvae are predators (feeding mainly on the larvae of the caloric flies) or parasitize on locust and stinging hymenoptera.
Over 50 synanthropic species (indoor flies, bazaar flies, hawks, etc.) are carriers of infectious agents of human and animal origin (cholera, dysentery, certain eye diseases, anthrax, trypanosomiasis, etc.). Sometimes the larvae of the fly cause miases in humans and animals, some are herbivorous, harm cultural plants (cabbage, onion, beet, flies, etc.). The fight against synanthropic flies is based on strict adherence to sanitary and hygienic rules in populated areas. It is very effective to treat rooms and places with different insecticides.

Fly are social insects.

This is unlikely. Unlike bees, flies can not communicate with each other, and they do not care about their offspring like ants, since their babies are born when their parents have long since died.

Flies are very prolific.

During 2.5 months of life, a housefly postpones from 600 to 2 thousand eggs. True, not all of them will later appear flies and not from all of the emerging individuals will survive to the childbearing age (30 hours of life) or the age of egg laying (9 days after fertilization). So – everything is relative.

The tabanus is not a fly.

As it were not so! A large, buzzing, terrible, blood-sucking animal and human fly. In villages, it often annoys large and small cattle. It lives near the water, in the forest zone, steppes and deserts. Blood is drunk only by female adult flies to get the opportunity to lay eggs. Males eat nectar flowers. It is curious that the flies fly at a speed more than three times the speed of all the familiar houseflies.

Flies are carriers of contagion.

Even house flies do not disdain carrion, what can we say about the rest. The special structure of the paws and jaws of flies promotes the transfer of various helminths, pathogens of tuberculosis, plague, poliomyelitis, cholera, typhoid fever, dysentery and many other terrible and unpleasant diseases by this type of insects.

Room flies live only at home.

In the end, they are, and it is true, difficult. They are mercilessly exterminated, both by colds and people, and by birds, day and night, scampering in search of food. Scientists have established that in the wild, most of the houseflies do not live and 3-6 days.

Flies do not see food.

Or they see, but very rarely, since their special eyes are not adapted to gazing at objects intently. By the smell of finding food flies also often can not. There is one thing left – by the method of a mouse poke, walking around and around, bumping into food and identifying it with special taste sensors located on the paws.

You can catch a fly by stealing it from behind.

A common misconception. The eyes of a fly are arranged in such a way that it can even look back. Therefore, if you really want to catch a fly, be honest with nature – come up front. You see, fleeing from you, the fly will fly directly into your palms by the inertia of the flight.

Flies do not pose a mortal danger to humans.

Depends on the region where you meet with them.For example, African flies can be transported in their saliva by an immunodeficiency virus from one person to another. This is due to the fact that unlike mosquitoes, the fly uses two tubes – one for sucking blood, and another – for injecting saliva. Biting the next object, the fly burps into his wound a small portion of the blood taken from the previous victim. Ask where so many HIV-infected people are from in Africa? .. Yes, even from the same chimpanzees, which flies bite at least us.

There is nothing good for a man to expect from flies.

Not true. Drosophila flies successfully used by scientists for a wide variety of experiments, and chitin, from which the protective covers of flies are made, is modified into chitosan, which is an excellent wound-healing preparation. Meat flies that destroy carrion play an important sanitary role in nature.
