Mosquitoes

Can anyone tell me why on earth these little blood-suckers were invented? What purpose could they possibly serve, other than to annoy me?

I got bit by one a few days ago. In my house. While I was sleeping. On my knuckle.

Whenever I get bit by a mosquito, the bite swells up huge. I must be allergic or something. Because of the location of this bite, it now looks like I either have a case of rheumatoid arthritis or a tumor on my knuckle. Oh... and it itches really bad and hurts like... well, yeah.

I'm convinced that mosquitoes didn't exist in the Garden of Eden. How could they exist in a paradise like that? Doesn't seem to me like much of a paradise if they are there.

I'm in favor of completely eradicating mosquitoes from the planet. I don't think we'd see any nasty effects when these become extinct. I know dragonflies and some types of fish feed on them, but I'm sure those species could find something else to eat.
