Mosquito

Only the female mosquito bites and takes the blood of warm-blooded animals. She does not really feed on blood. Scientists have found that she needs part of the blood to help more of her eggs to hatch. If the female mosquito takes warm blood, almost all of her eggs will hatch. If she does not take blood, most will not hatch. She does not really bite either. She puts her sharp tube through the skin and takes blood out by first pumping her saliva into the wound. Most people are allergic to mosquito saliva. This allergic reaction to the saliva causes a bump to grow where the female mosquito took blood. The male mosquito lives by taking plant juices from water plants and other soft land plants. He never takes blood.
