If it wasn't for the cute child like drawings this would be a truly terrible piece of link bait. As it is it's still pretty and, and I expect better from NatGeo.

Anyone who lives in a mosquito heavy area knows that mosquitos (like almost all airborne insects) go into hiding during heavy rain and/or wind.

From an io9 article on the same research: >> [Hu] and Dickerson constructed a flight arena consisting of a small acrylic cage covered with mesh to contain the mosquitoes but permit entry of water drops. The researchers used a water jet to simulate rain stream velocity while observing six mosquitoes flying into the stream. Amazingly, all the mosquitoes lived. The researchers used simulated rain drops on six mosquitoes…

^This I live in a mediterranean zone near a huge lake and during summer mosquitos are your every night companions (specially if you're working during late night hours). But when a summer storm brews the mosquitos disappear for two or three days. Why? This has been for me a recurrent question, and the answer has been always obvious: few of them survive being hit by raindrops. You can make 1000 theories about how our t…

It seems likely. Mosquitoes have like 3 neurons, and can't be built to deal with macroscopic events. More likely the species uses simple statistics to survive: enough eggs laid in enough places will survive the harshest downpour. The flying guys are only there to lay eggs after all. Seen from that angle, a mosquito is an eggs way of making another egg. Dying in rainstorms is not a problem.

>A study says a mosquito being hit by a raindrop is roughly the equivalent of a human being whacked by a school bus, the typical bus being about 50 times the mass of a person.

That is not a sensible comparison. When you scale something mass changes as the cube of dimension. Strength changes as the square of dimension. So small things are inherently stronger with respect to their mass.

Thanks for the math to back up my own doubt. Fortunately, the bus analogy appears to be added by the author as a bit of sparkle and does not get brought up again.

Surviving is not the same thing as actively seeking food.

I'm guessing it still sucks for them.

Very believable; how does the math work out?

> But because our mosquito is oh-so-light, the raindrop moves on, unimpeded, and hardly any force is transferred. So if the mosquito's weight is insignificant compared to that of the heavier and denser water drop and that's what keeps it from having the force transferred, would this equally apply to hailstorms? (Where our mosquitoes are pelted by small hail balls the size of raindrops)

You don't really find mosquitoes where you're likely to find hailstorms.

Are you thinking of sleet? Hail is associated with severe thunderstorms,[1] which definitely occur in areas with mosquito populations.

Earlier quoted context omitted.

In Spain we definitely have mosquitos, and most Augusts we have these summery storms, sometimes bringing also hailstorms (sizze varies though between drop sized ice and golfball sized ice)

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.
