　　No matter who you are or where you come from, one thing is certain: you are familiar to the mosquito, although you probably wish you weren't. Mosquitoes are everywhere. They can be found all over the world, and they come in more than 2,500 species(种). Somewhere, at some time, you have surely met at least one.

　　No one loves the mosquito. But unfortunately, the mosquito may decide who she loves. She? Yes, she. Do you know that only the female mosquito bites? Well, it's true. And it's not because she is unfriendly; she needs blood to reproduce.

　　Do you know how the female mosquito decides whom to bite? She is quite selective, and she chooses her victims(猎物) carefully. First, she uses sensors(感觉器) to find her victim. These sensors are located on her two antennae(触角) and her three pairs of legs. With these sensors, she tests your body moisture, body warmth, and chemical substances in your sweat. If she likes what she finds, she bites. But if you are not attractive, she'll reject you for another one. The next time a mosquito bites you, just remember that you are chosen. You are special.

　　If the mosquito likes you, she settles onto your, flesh very gently, and she breaks your skin with her long nose tip. Long nose tip? What's that? It's a kind of mouth and it sticks out just below the mosquito's eyes. It contains six sharp instruments called stylets. She thrusts all six stylets into your skin at once, and if she hits a blood pipe, she'll get a full dinner in about a minute. All this usually takes place so quickly and quietly that you may not have doubted anything is happening.

　　Why does a mosquito bite itch(痒)? The itch is not really from the bite. It's from the saliva(口水) the mosquito mixes with your blood to keep it from being blocked as she sucks it up her long nose tip. By the time the itch begins, she has gone.

　　And then what happens? Well after her delicious dinner, the mosquito is tired. She just wants to find a place to rest. Heavy with your blood, she picks a spot on a leaf, a wall or a stone to quietly lay her eggs. Just one drop of blood will produce hundreds of eggs.
