How fast are they, and how many live? National Geographic reveals 18 interesting facts about less favorite insects.
1. Mosquitoes have been known since the Triasical era 400 million years ago.
2. So far, a total of 3549 mosquito species have been registered.
3. The average mosquito weighs about 2.5 milligrams.
4. Average female muncher receives about five-millionths of a blood liter in food.
5. Mosquitoes do not find a host at random. They observe the movement by revealing infrared rays of warm bodies and chemical signals (mictuaries are drawn to carbon dioxide and lactic acid, among other chemicals) at a distance of 25 to 35 meters.
6. Mosquitoes are among the slowest insects and fly at speeds of 1-2.4 km/h.
7. Older people are often more interesting to mosquitoes because they produce more substances that attract them (zero dioxide and lactic acid).
8. Dark clothing attracts certain species of mosquitoes more than light - colored clothing.
9. Some studies indicate that mosquito victims ' movements increase the number of mosquito bites by up to 50 percent.
10. One study showed that a full moon increases mosquito activity to 500 percent.
11. As part of research on polar parts of Canada, scientists discovered their breasts, arms, and feet and recorded up to 9,000 mosquito bites per person in just one minute. Although it would take 1,200,000 mosquitoes to absorb all the blood from a man's body, at that rate a defenseless man would lose half his blood within two hours.
Twelve. Female mosquitoes take only one blood meal to lay eggs, while males feed on nectar.
13. The frequency of the mosquito's wing movement is 300-600 times a second.
14. Mosquitoes cause more deaths than any animal on Earth. They are carriers of various diseases, including malaria, dengue fever, and yellow fever that are transmitted to humans, and animals when mosquitoes feed on them, writes National Geographic.
15. When a female receives her blood meal, her belly expands and can receive up to three times its weight.
16. Mosquitoes prefer zero blood type, people with higher body temperature, pregnant women, and people who have difficulty breathing, producing higher amounts of carbon dioxide that attracts them.
17. The life span of a female mosquito is from two weeks to several months, while males live only one week.
18. Male mosquitoes find females by sound produced by their wings during flight.
