Default Why Raindrops Don’t Kill Those D***ed Mosquitoes!

Hint: They don't (can't) dodge the drops...
Why Raindrops Don’t Kill Those Damned Mosquitoes strange behaviors

"Mosquitoes, which thrive in hot, humid climates, are as adept at flying in rainstorms as under clear skies. That’s puzzling: Why aren’t the bugs – which each weigh 50 times less than a raindrop – battered and grounded by those falling drops? In fact, say David Hu, an assistant professor of mechanical engineering and biology at the Georgia Institute of Technology, and his graduate research assistant Andrew Dickerson, mosquitoes are hit by raindrops. Hu, Dickerson, and colleagues measured the impact forces of drops on both free-flying mosquitoes and custom-built mosquito “mimics” (small Styrofoam spheres of mosquito-like size and mass), and captured the interactions using high-speed video."

I suspect that if you go in search of mosquitoes in a rain storm, you will find them mostly taking shelter on the underside of leaves, something a styrofoam mimic would not have the intelligence to do.

When I was doing field work involving mosquitoes, I found that wind velocity and temperature were more important flight-limiting factors than rainfall per se. But it certainly is true that you would not find them flying in a downpour!
