Are mosquitos useful in anyway?

Spiders eat them. Also, dragonflies lay their eggs in the same waters as mosquitoes and their larva in turn eat the mosquito larva. So yeah, I'd say they're a pretty useful part of the food chain.

They are a conversation piece. (P.S. Purple martins do not eat them. Those birds fly in the sun in daylight and mosquitoes stay out of sunlight. Bats do eat them by the TON.) Makes one wonder about the utility of some of the things in the world.

That is a very good question. I know that purple martins eat mosquitoes but I don't know about any other insects. Once again good question.

Strengthening the human immune system. If they have West Nile or some other disease, and the human can't handle it, they can die. If they're dead they can't reproduce, and only the genetically fit will live. This is called survival of the fittest. The elimination of the weak genes is called evolution.

GO DARWIN!

They are part of the food chain, and are eaten by birds and other insects and amphibians.

other than spiders ants eat them

bird food, see birds going crazy by ponds

oh and i guess fish food

shame there are too many of their predators killed by what kills them

better question: Is there any way for humans to make the mosqios extinct!?

They spread disease and help control population?

Very useful for spreading diseases LOL
