Mosquito Facts...... Must be Known


Ah, mosquitoes, the insects that are universally hated the world over. These pesky, disease-carrying pests make a living by sucking the blood out of just about anything that moves, including us. But take a moment to look at things from the mosquito's perspective – it's a pretty interesting life.

  1. Mosquitoes are the deadliest animals on Earth.That's right, more deaths are associated with mosquitoes than any other animal on the planet. Mosquitoes may carry any number of deadly diseases, including malaria, dengue fever, yellow fever, and encephalitis. Mosquitoes also carry heartworm, which can be lethal to your dog.
  2. Only female mosquitoes bite humans and animals; males feed on flower nectar.Mosquitoes mean nothing personal when they take your blood. Female mosquitoes need protein for their eggs, and must take a blood meal in order to reproduce. Since males don't bear the burden of producing young, they'll avoid you completely and head for the flowers instead.And when not trying to produce eggs, females are happy to stick to nectar, too. 
  3. Some mosquitoes don't bite humans, preferring other hosts like amphibians or birds.Not all mosquito species feed on people. Some mosquitoes specialize on other animals, and are no bother to us at all. Culiseta melanura, for example, bites birds almost exclusively, and rarely bites humans. Another mosquito species, Uranotaenia sapphirina, is known to feed on reptiles and amphibians.
  4. Mosquitoes fly at speeds between 1 and 1.5 miles per hour. That might sound fast, but in the insect world, mosquitoes are actually rather slow. If a race were held between all the flying insects, nearly every other contestant would beat the pokey mosquito. Butterflies, locusts, and honey bees would all finish well ahead of the skeeter. 
  5. A mosquito's wings beat 300-600 times per second. This would explain that irritating buzzing sound you hear just before a mosquito lands on you and bites. 
  6. Mosquito mates synchronize their wing beats to perform a lover's duet. Scientists once thought that only male mosquitoes could hear the wing beats of their potential mates, but recent research on Aedes aegypti mosquitoes proved females listen for lovers, too. When the male and female meet, their buzzing synchronizes to the same speed. 
  7. Salt marsh mosquitoes may travel up to 100 miles from their larval breeding habitat. Most mosquitoes emerge from their watery breeding ground and stay pretty close to home. But some, like the salt marsh mosquitoes, will fly lengthy distances to find a suitable place to live, with all the nectar and blood they could want to drink. 
  8. All mosquitoes require water to breed. Some species can breed in puddles left after a rainstorm. Just a few inches of water is all it takes for a female to deposit her eggs. Tiny mosquito larva develop quickly in bird baths, roof gutters, and old tires dumped in vacant lots. If you want to keep mosquitoes under control around your home, you need to be vigilant about dumping any standing water every few days. 
  9. An adult mosquito may live 5-6 months. Few probably make it that long, given our tendency to slap them silly when they land on us. But in the right circumstances, an adult mosquito has quite a long life expectancy, as bugs go. 
  10. Mosquitoes can detect carbon dioxide from 75 feet away.Carbon dioxide, which humans and other animals produce, is the key signal to mosquitoes that a potential blood meal is near. They've developed a keen sensitivity to CO2 in the air. Once a female senses CO2 in the vicinity, she flies back and forth through the CO2 plume until she locates her victim.
  11. There are more than 3,500 species of mosquitoes. About 175 of them are found in the United States, with the Anopheles quadrimaculatus, Culex pipiens,Aedes aegypti and Aedes albopictus (Asian tiger mosquito) among the most common. The Anopheles is a malaria carrier, and the other three are known to spread various forms of encephalitis.
  12. West Virginia has the fewest species of mosquitoes. There are 26 in the mountainous state, while Texas has the most with 85. Florida is a close second with 80 identified species.
  13. Mosquitoes don't have teeth. The females “bite” with a long, pointed mouthpart called a proboscis. They use the serrated proboscis to pierce the skin and locate a capillary, then draw blood through one of two tubes.
  14. Mosquitoes spend their first 10 days in water. Water is necessary for the eggs to hatch into larvae, called wigglers. Wigglers feed on organic matter in stagnant water and breathe oxygen from the surface. They develop into pupae, which do not feed and are partially encased in cocoons. Over several days, the pupae change into adult mosquitoes.
  15. Mosquitoes have six legs. They also have a head, thorax and abdomen. On the head are two large compound eyes, two ocelli (simple eyes), two antennae and a proboscis. Two large, scaled wings sprout from the thorax.
  16. Midges and crane flies are often mistaken for mosquitoes. Biting midges are smaller, have shorter wings and tend to feed in swarms. Mosquito traps often attract and kill biting midges. Meanwhile, crane flies are much larger than mosquitoes – up to 1 ½ inches long in some cases – and do not bite. 
  17. Mosquitoes can smell human breath. They have receptors on their antennae that detect the carbon dioxide released when we exhale. Those plumes of CO2 rise into the air, acting as trails that the mosquitoes follow to find the source. 
  18. Sweat helps mosquitoes choose their victims. Our skin produces more than 340 chemical odors, and some of them smell like dinner to mosquitoes. They are fond of octenol, a chemical released in sweat, as well as cholesterol, folic acid, certain bacteria, skin lotions, and perfume. 
  19. Mosquitoes have been around since the Jurassic period. That makes them about 210 million years old. They've been mentioned throughout history, including in the works of Aristotle around 300 B.C. and in writings by Sidonius Apollinaris in 467 B.C. 
  20. The bumps from mosquito bites are caused by saliva. While one tube in the proboscis draws blood, a second pumps in saliva containing a mild painkiller and an anti-coagulant. Most people have minor allergic reactions to the saliva, causing the area around the bite to swell and itch.
