10 Mosquito Facts and why we should not kill them
Mosquitoes appeared in the Jurassic era, more than 175 million years ago, so that even dinosaurs got them. Here is the list of the 10 Mosquito Facts which prove why we should not kill them.
Mosquitoes belong to the detachment of Diptera (relatives of flies, “Mosquito” in Spanish means “small fly”), suborder Nematocera (“with thin antennae antennas”), the family Culicidae.
There are more than 3000 species of mosquitoes, living both in the arctic tundra and in tropical moist forests. Moreover, all types of mosquitoes pass into the active state at a temperature of 12.7 degrees Celsius, so the greatest concentration is, of course, in warm and moist forests, marshes, dry deserts.
The peak of activity of mosquitoes falls on twilight and night, during the day they rest, hiding in houses and plants. In the afternoon, mosquitoes are food for other species of animals.
Mosquitoes can be of different sizes, up to 12.5 mm. Fossil mosquitoes reached 5 centimeters in length!
Mosquitoes do not bite but suck. 1200000 mosquitoes are enough to drink all the blood from a person. They are, of course, theoretical calculations, because before that a person will die of irritation and pain shock.
An experiment in the Canadian tundra showed that people with bare arms, legs, and torso in a minute receive 9,000 bites of young mosquitoes. At this rate, for two hours a person can lose half of the blood.
Only female mosquitoes bite. They bite both humans and other vertebrates, from elephants to mice and turtles, sucking their blood. Such food is necessary for females to bear offspring. Some mosquitoes can produce offspring without pre-sucked blood, but at the first opportunity, they do not refuse it (Culex species). One drop of blood gives life to thousands of mosquito eggs. The most “tasty” for mosquitoes is the blood of people with the first and second blood group, and also children.
Males of mosquitoes do not deal with sucking blood – they feed on plant food and nectar.
The mosquito sting looks simple, but under great magnification turns into a complex construction. It consists of six parts – two tubes, saliva, and nutrient, surrounded by two sharp lower jaws and two “scalpels” with sawed teeth. All 6 parts are enclosed in a protective sheath along the entire length. When the bite stings plunge into the skin a few millimeters until it reaches a small blood vessel.
Mosquitoes have olfactory and thermo-sensory organs located on a pair of antennas, and three pairs of legs that guide them towards the victim, who poses as an increased concentration of carbon dioxide, heat, and sweat.
In the Arctic, where most of the northern birds nest in the short cold summer, mosquito larvae are often the only source of their feeding. But even those mosquitoes and larvae that managed not to become the food of birds or fish will still live in good health. The myriad of insects carries tons of chemical elements in their bodies: carbon, nitrogen, phosphorus, calcium, iron, manganese, molybdenum, boron, which the plants need so much. It is assumed that mosquito clouds are sometimes the only biological transport for some trace elements, without which both the grass and the mighty trees lose their power.
Carrying out infections, mosquitoes serve as the most important stabilizer of ecosystems since they regulate the number of animal populations, as well as predators.
