Mosquito
Mosquitoes sometimes are vectors which give people deadly disease such as malaria, elephantiasis, yellow fever, dengue, and encephalitis. Millions of people, especially children and the elderly, die in developing countries every year because of these diseases.
Only female have the mouth parts for sucking blood. When sucking blood, they stab two tubes into the skin: one to inject an enzyme that inhibits blood clotting; the other to suck blood into their bodies. They use blood only for their eggs. For food, both males and females eat nectar and plant sugars.
              Also, because they actually don’t choose human blood because they prefer blood of horses, cattle, and birds.
              Although we kill many mosquitoes in usual day, this has little effect, and it is said that global warming will likely increase their number and range.

  1. It makes me feel itchy just to think about the mosquitoes. It's scary to know that mosquitoes are growing in numbers due to the global warming!
