I’m waiting for an explanation of the attraction of a mosquito ringtone. ... Oh, I see.
Although mosquitoes carry West Nile virus, malaria, encephalitis, yellow fever and dengue fever, not to mention that irritating blood thing they do on your skin, teenagers download a high-pitched buzzing because its high frequency is a tone that allegedly can’t be heard by most adults. Thus incoming messages can arrive and only the teenager knows to look without a teacher landing all over them or parents objecting to post-midnight calls.
So in recognition of mosquito ringtones and teenagers’ evasive tactics, let’s check out that insect.
Warning: I can’t shorten the information to Tweeter proportions.

What: 170 mosquito species in North America, some in the Arctic.
Ancient history: Has been around for 100 million years.
Family ties: In the Culicidae family, which includes dipterian flies.
What’s in a word? Brits call mosquitoes gnats.
Record-setting: They are the most important factor in spreading death by disease.
Culinary tastes: Only females go after blood, needing a protein in a blood meal for egg development, not food. Many species prefer small herbivores to humans. Both sexes dine on nectar.
Sight lines: Because they detect humans by movement, we are safe if 30 feet away from a mosquito.
Scent sensitive: At 10 feet, sensitive antenna receptors sense blood near the skin’s surface. High humidity extends their receptors’ range. Carbon-dioxide exhalations and body scent (and warmth) give us away.
Keeping score: According to those in the know, it would take more than a million bites to drain an average-sized human’s blood, and it would take about 20,000 mosquitoes to weigh a pound.
Pseudo bite: A mosquito bite is a misnomer. They pierce, saw and rip to create a blood pool but, technically, don’t bite. Now don’t you feel better?
Scratch, scratch: That welt is an allergic reaction to the saliva that’s injected into the skin as an anti-coagulant.
Fast track: From egg to adult in 4-7 days
Breeder Olympics: Lays 1,000-3,000 eggs in her short (a month or so) life.
Birth control: Start with eliminating standing water on your property.
Predator: Dragonflies’ appetites for mosquitoes provide one natural control.
Upside: Larvae and pupae are a food source for fish.
Winged thing: Wings beat 250-500 times a second. Females’ slower wing beats create a different pitch and attracts a swarm of males. Mating is done in the air but not in excess. One mating yields many batches of eggs.
Pack a bag: While some species travel dozens of miles, most are homebodies and stay within a mile of birth.
Urban myth: Eat a banana and increase your chances of being a food source.
Lighten up: Light colors attract more mosquitoes than dark colors.
Moving target: Mosquitoes fly forward and backwards, up and down and sideways, making them a tiny moving target. In addition, the moving air from your attempted swat can blow them away.
Zapper downside: Bug-zappers kill indiscriminately, including hundreds of beneficial insects.
Killer sprays: Backyards are often sprayed and fogged but both kill useful insects.
In the spotlight: Stars of the 1995 movie “Mosquito!” The plot, such as it is: Alien ship crash lands on Earth. Mosquitoes feed on bodies, mutate and become huge. Chase humans in a feeding frenzy (a generous two stars).
Slap-a-thon: Finland hosts the World Championship of Mosquito Killing. Competitors get five minutes each to mount the death toll with their bare hands. Winners are usually in single digits.
