On Earth at any given time about 10,000,000,000,000,000,000 insects inhabit. Each of us has a half billion beetles. But some of them are so desperate that even one — it's too much. Here are five of them, that you would prefer not to see any cost.
The human botfly
The human botfly, Dermatobia hominis — one of several species of insects whose larvae are parasitic in man.
Eggs gadfly transferred more than forty species of mosquitoes and flies, as well as a variety of ticks, mosquitoes caught female oestrus, attaches to them their eggs, and then let go.
Larvae hatch or when feeding mosquito larvae, and then uses the bite as a point of entry into the body, or the eggs will simply fall to fly when it lands on the skin. The larvae develop in the subcutaneous layers, and after about eight weeks to get outside to pupate for a period of about a week — usually in the soil. The adults are small gray flies that resemble meat.
This kind of insect is typical for the Americas and spread from Southeast Mexico (from the central Veracruz) to northern Argentina, Chile and Costa Rica, but fortunately not so numerous (and not so nocuous) to get the status of this pest.
Since larvae can survive for a full eight-week cycle only if the wound is not infected, patients rarely face contamination, if they do not kill the larvae, but it can not completely remove it. Larvae can even allocate secret antibiotic that helps prevent infection during her feedings.
The army ants
The name "army ants" covers more than two hundred species of ants in different families, due to the formation of aggressive predatory groups called "raids", in which a huge number of ants feeding on a certain territory.
Another common feature is that the army ants do not build permanent nests, a column of soldiers moves almost as long as it exists.
All species are members of the true ant family Formicidae, but there are several groups that independently evolved the same basic behavioral and ecological syndrome. This syndrome is often called the "Legion of behavior," and it is an example of convergent evolution.
Most of the army ants of the New World belong to the subfamily Ecitoninae, which contains two groups — Cheliomyrmecini and Ecitonini.
Initially it was thought that the lines of the army ants of the Old World and New World developed independently of each other — that is an example of convergent evolution. But in 2003, the genetic analysis of different species has shown that they all evolved from a common ancestor who lived about a hundred million years ago during the division of the continent of Africa and the Americas.
African honey bee
African honey bee (Apis mellifera scutellata) is a subspecies of the Western honey bee. It is found in central and southern Africa, although the habitat in the southern Cape Town it is replaced by a honey bee, Apis mellifera capensis
These subtypes are part of the line of African bees (also known as "killer bees"), which are common in America.
Bite only African bees more poisonous than a single bite of the European bees, but the African bees react to threats faster than European. They are sent to suppress the threat of three to four times more workers than the European species. They also pursue the offender at a greater distance from their hive. And while people die from a hundred — three hundred bites, it was estimated that the median lethal dose for an adult is five hundred — one thousand one hundred bites.
Paraponera — genus of ants, consisting of a single species, known as a small giant ant-hunter, or bullet ant (Paraponera clavata), named so because of its extremely powerful bite, which is said to be just as painful as the bullet wound.
Workers reach a length of 18-30 mm and resemble hard, reddish-black, wingless wasps. Paraponera are predators and like all primitive poneromorfy no signs of polymorphism in the caste workers. The Queen is not much more than the workers. They inhabit tropical rain forests from Nicaragua to Paraguay. Ant bullet locals call «Hormiga Veinticuatro» or «24-hour ant", because of the pain of the bite, which lasted 24 hours.
Japanese giant hornet
Japanese giant hornet is a subspecies of the Asian giant hornet. It is a large insect and adults can reach lengths of more than four inches, and a wingspan of more than six inches. He has a large yellow head with large eyes and a dark brown abdomen with brown and yellow stripes.
Workers collect hornets feed for young animals. Their diet consists of a large number of insects, including agricultural pests, which is why the hornets find useful.
Workers dismember the bodies of their victims in order to deliver to the hive only the most nutritious part of the body — such as flying muscles.
In the hive workers chew prey into mush, which they fed to larvae, and that in turn secrete a fluid which supplies workers. This fluid — the only substance that workers learn during his adult life, which is quite remarkable, given that they can fly up to a hundred miles a day and reach speeds of up to forty miles per hour.
This fluid can develop intense muscle activity over a long period of time and produced artificially for athletes. In many mountain villages fried Japanese hornet is d
