Why do mosquitoes exist?
They do not benefit the world or the nature in any way that I can think of (for example, bees produce honey and some others help to spread flower seeds); unlike some insects who do not cause any harm but only to live in their own terms, vicious bites and transmitting disease are what they are famous for.
Mosquitoes are what I call the "mini-vampires". In order to generate batches of eggs, the female ones have to seek for blood meal. We the humans obviously are a good blood source for them. Of course, the poor little species are doing what they are made to do, and have absolutely no control over their own habitual. Just like the humans and any other type of living species, they do anything to live regardless how short their life cycle is.
Nevertheless, the "millions" of bites that I get from them are unforgivable. They sting you before you realize it; they get away with a full stomach and leave you a swollen bump that itches for days; above all, if any of them unfortunately dies under my palm, the dead little body always manages to make me feeling a second of guilt for killing such a small, helpless creature.
If Noah's Ark was a true story, he shouldn't have let the mosquitoes to sneak into the boat. It was a mistake... indeed...
