Mosquitoes are a family of insects encompassing over 3,500 recognised species. Most are associated with warm and humid regions, although they can be found in cooler areas and even in snow.Most mosquito species feed on nectar, however, the females of some species drink blood for the nutrients they need to develop eggs. They inject saliva that contains an anti-coagulant to prevent their proboscis from getting clogged up. Mosquitoes transmit diseases such as malaria to many millions of people every year.
