“The video below shows what happens when a mosquito finally finds and pierces a blood vessel. On average, they drink for around 4 minutes and at higher magnifications, [researcher Valerie] Choumet could actually see red blood cells rushing up their mouthparts. They suck so hard that the blood vessels start to collapse. Some of them rupture, spilling blood into the surrounding spaces. When that happens, the mosquito sometimes goes in for seconds, drinking directly from the blood pool that it had created.”
