House flies - the most common insects, and, interestingly, in the wild, they almost never occur.Everyone knows what they look like, but to answer the question of how many live flies, not everyone is ready.
flies are found almost everywhere on Earth.They have appeared on this planet for a long time.China has found a fly that lived as scientists have identified about 145 million years ago.
Before answering the question of how many live flies, consider them carefully.How do they look externally?The length of the body of the adult fly is approximately five to ten millimeters, the color most often - gray, the abdomen is slightly yellowish in color, and on the upper side of the chest could be seen a few black stripes along the body.Upon closer inspection you can see that the body is covered with flies rare, but quite long hairs.Eyes flies - large, faceted, their color - brown.The distance between the eyes in flies, females slightly larger than the male flies.Small details distinguish the fly eye is bad, however, they can distinguish the slightest blink of light.Fly-fly females are slightly larger male, but identify with the naked eye is quite difficult.
Feed houseflies mostly liquid diet, although they, too, use strong, but it are first dissolved by the saliva.
Flies are very fertile and multiply rapidly.The female at a time can be postponed about 100 eggs, their size is about one millimeter in length.How many live flies?Not for long, but in his short life, these Diptera lay huge numbers of eggs, depending on breeding conditions.They live usually near the site launch.Due to wind they may travel a great distance.The main food for houseflies are food waste.
must say that the housefly insect is very dangerous because it can carry on themselves a variety of infections, disease, parasite eggs.It is necessary to apply preventive measures: one can not, for example, to store leftovers, sewage and food waste in the open air.Often, for the destruction of flies use special chemicals - insecticides.But in residential areas such substances can not be used.Therefore, people use sticky tape and other bait, and placed on the windows of safety nets, through which the living room is not no flies fly.
So many live flies?It depends on the type typically have a lifespan of a few days to two and a half months.The average duration of their life is about three weeks.Lifespan flies depends on air temperature.The most optimal temperature for these insects - room (21-24 degrees Celsius).Under these conditions, the fly can live to more than two months.However, the vast majority of these insects do not live up to the age of ten days, as they often become food for predators.
short lifetime they make tremendous ability to reproduce.One female in her short life can defer up to two thousand larvae, each of which develops twenty-five days, after which it becomes a pupa.After three days of it is born fly that thirty-six hours after his birth already able to reproduce.It turns out that for the year may be replaced by some twenty generations of flies.
Lifetime flies becomes greater if it becomes dormant in the winter.In this case, a fly in the state of suspended animation can spend the winter, and when it becomes warm, otogrevshis again be able to come to life.And in sleep may fall not only adults but also larvae.
