Furry Logic: The Physics of Animal Life - Matin Durrani, Liz Kalaugher

"Can mosquitoes fly in the rain? It’s one of those questions it doesn’t even seem worth asking. Like, was Albert Einstein a genius? Mosquitoes thrive in the tropics, where it rains a lot. They need pools of water to drink from and to lay their eggs in. So of course they can fly in the rain. Who’s seen mosquitoes dashing for cover in a storm?

 

But hang on a minute. Raindrops plummet from the sky at nearly 10m (33ft) per second, or more than 35km per hour (22mph). The heaviest weigh 100mg, about 50 times the mass of a mosquito. Each drop is roughly the same size as the insect, but mass for mass, a stationary mosquito receiving a smack from a raindrop is like a 5,000kg (5-ton) lorry cannoning into a 100kg (220lb) human. In a downpour, a mosquito is hit by a raindrop roughly once every 25 seconds. Flying in the rain sounds like an online road-crossing game where the mosquito must constantly dodge impacts with heavy vehicles. How does it survive?"
