there's a large amount of endangered and critically important species for which the strongest reason the general public accepts for why we should accommodate them is "they eat X in mosquitos every night"
The serious proposals to eliminate mosquitoes only propose to eliminate the mosquito species that carry nasty human diseases. If those species were eliminated other mosquito species would quickly expand to replace the eliminated species.
So that's good for the birds, and bad for the humans that want to get rid of all the pesky annoying mosquitoes, not just get rid of mosquito born disease.
Yes, all the ectoparasites, look it up. We've eliminated most endoparasites that used to live inside us. If we figure out how to, we should eliminate the ectos, including mosquitos.
