A Purdue researcher and a team of scientists working on a new insecticide argue that mosquitoes should not simply be made extinct due to their role in various ecosystems. Catherine Hill, a professor of entomology, and her team are developing an insecticide that will suppress mosquitoes' ability to transmit diseases without killing the insect or interfering with other life forms. The team is based in Discovery Park, a research park dedicated to using interdisciplinary teams to solve global problems. Hill's research was one of the winners of Discovery Park's Big Idea Challenge, a program that provides resources to interdisciplinary teams with innovative research.
"For the last 20 years I've been trying to figure out how to kill mosquitoes, and then I had this epiphany where, morally, I'm just not OK with it anymore," she said.
There has been a lack of research in preserving mosquitoes because researchers have looked mostly at ways to eradicate them. Therefore, Hill thinks it is essential to consider all the possible effects of wiping out an organism that has existed for thousands of years. She points out that mosquitoes have co-evolved with many species, so there are likely other organisms that depend on them as a food source.

Should there be a "Save the Mosquito" movement?

Your rebuttal is also pure conjecture. I'll add my own and say that it would be much more surprising if removing a major food source from the food chain left things "nearly identical". A single brown bat can eat 1000 mosquitoes an hour [batrescue.org].
Who cares about brown bats? How about owls, snakes, raccoons, etc. that eat the brown bat. You can quickly see there are knock-on effects to disrupting the food chain. Nature has been balancing it for eons. Predicating the effects is not trivial, maybe not even possible with our current technology (look at all the ecological disasters humans have caused thinking they know better).

In the couple of places where mosquitoes have been totally eradicated, no adverse effects have been reported. It's true the places were small islands, and I haven't checked back recently, but such evidence as exists seems to imply that the eradication of mosquitoes would yield no adverse result.
Clearly this needs to be confirmed on a broader scale before going global with the project, and probably a few should be kept in reserve in case it turns out in the future that they are, indeed, necessary. But the evidence I'm aware of indicates that a push forwards is desirable. However, some of the proposed methods seem questionable. In particular there is a small amount of cross species gene transfer that happens naturally. It's at quite a low level, but it's still enough to make some of the proposed methods worrisome. (IIUC the cross species gene transfer is usually mediated by a virus that uses reverse transcriptase, and it also seems as if there is often a need for a bacterial infection that moves from species to species picking up plasmids, and releasing them when injured.)

Mosquitoes were introduced to the Hawaii islands. They seemed to function as a ecosystem just fine before the mosquito.

Also, there are thousands of species of mosquitoes, and only a handful (20 or so) that target humans. Let's just wipe-out the 20 "bad" ones.
Hey, it worked for smallpox. We killed off the passenger pigeon (nasty creatures left droppings everywhere), the short-faced bear, the auroch, etc. etc. etc... Life goes on, but better.
