There are 3000 different kinds of mosquitoes and a worldwide population of 100 trillion!! Most are in tropical climates, but there are mosquitoes in arctic and desert regions. They can fly up to 10 mph, dart between raindrops and even fly backwards. Most live and die close to where they hatch, but some are strong flyers that travel many miles in search of a victim.
Only female mosquitoes bite. They require a blood meal in order to develop eggs to make more mosquitoes. Most female mosquitoes lay their eggs on standing water. Stagnant ponds, ditches and fresh or salt water wetlands are favorites, but even a few tablespoons of water in a flower pot or old auto tire will do. The eggs hatch, become swimming larvae, then pupae and finally flying adults. Mosquito larvae are an important source of food for certain fish, birds, bats and other animals.
Why mosquitoes bite us and why we shouldn't let them.
In their quest for blood, mosquitoes may bite birds, frogs, snakes, and mammals, including people. Some, called peridomestic mosquitoes actually live and breed around homes just to be near us. 24 hours or so after hatching, a female mosquito flies off in search of a meal. She homes in on body warmth, odor, moisture and the carbon dioxide we exhale. When she bites, the mosquito injects a bit of saliva that slows coagulation so blood flows freely. It's your body's allergic reaction to the saliva that caused the welt and itching sensation.
