Life span flies
How many flies live depends on weather conditions, habitat, time of year. In the world there are about 5 thousand. species of flies. They differ in size, lifestyle, nutrition. On the territory of our country is ubiquitous common fly, home or apartment. At the end of the summer, the fly-flyer appears in the man’s house. On the street is often found fly meat or dead.
Appearance Description
All flies are similar. morphological signs.
- The body is oblong, densely covered with fibers. A fly consists of a head, chest, abdomen. Transparent wings on back, antennae on head. 6 pairs of limbs that allow the insect to stay on any surface in a horizontal, vertical position.
- The head is small, most occupy faceted eyes. Behind them is placed three simple eyes. The mouth apparatus, the proboscis, departs from the lower jaw. In blood-sucking flies, it is piercing, cutting-sucking. All the rest gives the opportunity only to lick the food.
- The extremity is five-segmented, the organs of smell and touch are placed on the last segment. Paws fly analyzes the quality of food better than a person's tongue. Fat glands on the legs allow the fly to stay on smooth surfaces and ceiling.
- The wings are transparent, only two pairs, which distinguishes flies from other insects.
- Body colors are different - gray, green, blue, spotted, black. For home pest is characterized by a gray color.
Most species are egg-layingbut there are viviparous. Eggs are small, oval are placed in heaps. The larvae are off-white or yellowish.Have the shape of a worm. Three stages of development take place, in the last phase of life they pupate. Pupa dark color.
Life cycle
How much a common fly lives depends on the conditions. Shortens the period of adverse climatic conditions, enemies, poison. The life cycle of a fly at the developmental stage has been studied very well. Insect becomes active with the onset of heat. The first warm rays of the sun make them get out of shelters. They belong to day creatures, prefer to “sleep” in the dark.
The development cycle of a fly begins with an egg. Formed inside the female after fertilization. Some species are viviparous. The first instar larvae are reproduced into the light, which accelerates the development of insects for several days. Under favorable conditions, worms emerge from the eggs within 24 hours.
The larvae, they are worms, maggots, go through 3 stages of development, but do not shed, just increase in size from 1 mm to 15 mm. The development of a fly at this stage takes about 10 days. The female lays larvae or eggs in groups, about 200 eggs can reproduce in one laying. For all his short life, he defers in the range of 20 thousand pieces.
The maggots feed on decaying organic matter. They live in feces, slop, pus, rotting plants, meat, corpses. Upon completion of development pupates. The larvae of most species burrow into the soil. Pupa flies stationary, dark-colored, oval-shaped. An adult fly emerges on the surface in 1-3 days. How many days the whole life cycle lasts from egg to imago - about 20 days.
On a note!
The developmental stages of some species of flies may differ. Pupae often hibernate, continue to develop in spring. Some larvae do not have time to go through the entire life cycle of development, continue after wintering.
Vital activity of adults
The life of a fly after birth begins with fertilization. The main task of the female is to lay eggs, she does it with a regular frequency. The female in some species of this family lives without food, energy reserves are still missing from those that the insect received, being a larva.
Among the flies there are inhabitants of the wild nature, synanthropic species that live in close proximity to humans. There are township, semi-village, pasture. The latter are attached to livestock, the larvae develop in the litter,faeces or on the body of the animal.
Where the village or city flies live - in the house, apartment of the person. They feed on the remnants of food, crumbs, waste in the garbage can, as well as particles of sweat. By the end of the summer in the human house appears flythat hides from the cold of the night. This insect feeds on blood, so a person often feels painful bites on him.
On a note!
By semi-village flies include meat, carcass. These insects are different large sizebrilliant body with modulations blue, green. Power source serves decaying meat, vegetables, feces, manure. Periodically can fly into the house of the person, which is very undesirable. Meat Flies are carriers of many diseases. The most common of these is intestinal infections, the most dangerous is leprosy.
Fly lifespan
Theoretically, an insect at the imago stage lives no more than 2 weeks. The life span of a fly is shortened due to the presence of natural enemies. How many flies live in an apartment depends on the activity of the person.
If the insects do not interfere, they do not hurry to die, a happy life will safely live for 2 months.In the wild, some members of the family live only 14 days. Using all sorts of traps insect life is rapidly shortening. Immediately begin to die pests from the poison, which a person often uses in the form of an aerosol, spray, solution.
The longevity of the flies may increase if winter is to occur. Insects die or fall asleep, depends on imaginative imago. Their task is to find a safe place for wintering. Where flies overwinter: in the crevices of walls, window openings, basements, any secluded places with cool temperatures. Otherwise, the insect dies under the influence of cold. Egg laying in winter stops.
At the end of September, flies become slow, fly a little. They are easy to slam palms, which previously could not be done. Slow down life processes. In a secluded place, the insect stops moving, which allows it to successfully winter.
In this state it remains until mid-April. With the onset of warm days wakes up, proceeds to an active life. In a warm cozy apartment a fly can wake up ahead of time. Then she is destined to either die or fall asleep again.
