You find them in these areas. When it gets cold there tends to be far fewer of them.

And compared to the equators its nearly incomparible.

Cold isn't required for hailstorms. The ice forms at altitude. We have a lot of hailstorms in the spring and summer in Colorado, and while it isn't the mosquitoiest place I've ever lived, there are mosquitoes.

[acyacy]

Compared with where its mosquito haven like by the Equator?

I suppose raindrop vs hailstone is a reason is one of the reason's the density issues are so different.

[Dove]

Yeah. Mosquitoes are densest in the tropics where hailstorms are rare, but just about everywhere on earth short of Antarctica has some mosquitoes. I'd think mosquitoes would meet hailstones occasionally, though I can't really see the mosquito surviving it.
