only the females do so I would say about 1/2 unless the ratio between male and female isn't 1:1
On the average, mosquitoes take one millionth of a gallon of blood with each bite. That means it would take 1,120,000 bites to drain all the blood from an average adult human.
Mosquitos are a member of nematocerid flies. Mosquitos are blood sucking pests and carry many deadly diseases. There are several types of mosquitos. They say mosquitos can transfer up to 700 million dieseases.
Mosquitoes are harmful because they are vectors for many human diseases. When they bite people to feed on blood they may pick up a disease form the person they bite. Then a few weeks later they go out and bite a second person and in doing so pass on the disease form the first person. The mosquito is the biggest killer of humans on the planet at the moment.
Only the female is capable of drinking blood, an act called haematophagy. Females do not require blood to survive, but they need supplements, such as protein and iron, to enable them to develop and lay their eggs to reproduce and make some more mosquitoes.WHY DO MOSQUITOES NEED YOUR BLOOD
twenty thousand million
There are many like leaches, ticks and mosquitoes.
Many bugs do that, take mosquitoes for example, they bite u often in the summer!!!!!!!!!!!!!!!!!!!!!!!!!!!!
A parasite lives on another organism. Not all microorganisms are parasites. Many parasites are very small and are called microorganisms. Many algae are microscopic and are microorganisms put do not live on any other organisms. Mosquitoes need blood and will bite humans but they can be seen. They are parasites since they need a blood meal.
It's just the balance of nature. Mosquitoes (along with many other insects and animals) exist to balance each other out. Bites are the fault of the female mosquito, who punctures your skin and sucks your blood. A natural mosquito bite itch reliever would be toothpaste, lemon juice, and some more, but I can't remember all of them. Go on google and search "Natural mosquito bite itch reliever" for more info.
Mosquitoes feed on nectar and plant juices, but in many species the mouthparts of the females are adapted for piercing the skin of animal hosts and sucking their blood. Female mosquitoes, however, need to nurture their eggs and they can only do this by providing the baby mosquitoes with protein to eat.
Other than the fact that they are annoying parasites that leave itchy spots on your arms when they bite, mosquitos are also disease vectors. This means that if they bite something that has a disease, they can transmit that disease to the next thing they bite. The original diseases people discovered they carried was malaria and yellow fever. For more info on this, please see the related link below:
yes zombies do drink blood but they only drink blood when they find lots of blood or/and many people dead
