I like that a lot. I think because of their ability to fly and general ideology on life they would be quicker to unify between hives. I also think a massive barrier between themselves and how their portrayed to the other races will be language. With no vocal cords or even the ability to make noise out of their proboscis or breathing siphon their language is based entirely of of pheromones and vibrations. This combined with their uncanny nature will severely limit any attempts at diplomacy. Another interesting thing in irl mosquito larvae is that they are the same size or bigger than the adults, as well as much heavier. These mosquito people larvae, although much less intelligent (maybe not even sentient yet), could be an interesting extension to the mosquitoes militaristic capabilities. Maybe even though the average Mosquito-Folk's combat ability is poor, their young could be proficient in combat underwater. This could be interesting to see how the mosquitoes would react when they have the upper hand in water based combat considering they were kind of forced into their liberal ideology due to their stature especially if there are are going to be any water based races. This could also be an interesting tree of technology finding ways to maximize the time spent in larval form while also being well fed and prepared. (sorry I took so long to reply). Below is an image of a real mosquito larvae.
