The Loathsome, Lethal Mosquito from Ted Ed
Everyone hates mosquitos. Besides the annoying buzzing and biting, mosquito-borne diseases like malaria kill over a million people each year (plus horses, dogs and cats). And over the past 100 million years, they’ve gotten good at their job — sucking up to three times their weight in blood, totally undetected. So shouldn’t we just get rid of them? Rose Eveleth shares why scientists aren’t sure
A raindrop hitting a mosquito in flight is like a midair collision between a human and a bus. Except that the mosquito survives.
Video Description:
In the study of insect flight, adaptations to complex flight conditions such as wind and rain are poorly understood. Mosquitoes thrive in areas of high humidity and rainfall, in which raindrops can weigh more than 50 times a mosquito. In this combined experi- mental and theoretical study, we here show that free-flying mosquitoes can survive the high-speed impact of falling raindrops. High-speed videography of those impacts reveals a mechanism for survival: A mosquito’s strong exoskeleton and low mass renders it impervious to falling drops. The mosquito’s low mass causes raindrops to lose little momentum upon impact and so impart cor- respondingly low forces to the mosquitoes. Our findings demonstrate that small fliers are robust to in-flight perturbations.
