Mosquitoes are known from as far back as the Triassic Period – 400 million years ago. In North America, they were detected since the Cretaceous Period – 100 million years ago.
There are about 2,700 species of mosquito. There are 176 species in the United States.
The average mosquito weighs about 2.5 milligrams.
The average mosquito takes in about 5-millionths of a liter of blood during feeding.
Mosquitoes find hosts by sight (they observe movement). This occurs by detecting infra-red radiation emitted by warm bodies, and chemical signals (mosquitoes are attracted to carbon dioxide and lactic acid, among other chemicals) at distances of 25 to 35 meters.
Mosquitoes fly an estimated 1 to 1.5 miles per hour.
Salt marsh mosquitoes can migrate up to 40 miles for a meal.
Bigger people are often more attractive to mosquitoes because they are larger targets and they produce more mosquito attractants, namely CO2 and lactic acid.
Active or fidgety people also produce more CO2 and lactic acid.
Women are usually more attractive to mosquitoes than men because of the difference in hormones produced by the sexes.
Blondes tend to be more attractive to mosquitoes than brunettes.
Smelly feet are attractive to mosquitoes – as is Limburger Cheese.
Dark clothing attracts mosquitoes.
Movement increased mosquito biting up to 50% in some research tests.
A full moon increased mosquito activity 500% in one study.
