I mean, come on. What reason do they have to exist? Flies, at least, come from maggots, which help to break down dead organic matter. Spiders, they kill the flies and other bugs. Frogs and lizards eat mosquitoes, so I guess you could say that’s what they’re for, but frogs and lizards eat other insects as well, so they could easily get along without them. So why in the FUCK do we need mosquitoes? They’re just a big pain in the ass, and I hate them! Lol.
