Adding insult to injury… mosquitoes don’t just suck our blood — they urinate on us at the same time!
…perhaps it wasn’t an artery; perhaps Betty is urophobic.
When a mosquito sucks blood from a human – and only pregnant female mosquitoes do this – it takes in twice its body weight in blood. To decrease this added weight, the mosquito urinates on its victim to release fluids.
Researchers have discovered that introducing a diuretic hormone into the mosquito causes the mosquito to excrete fluid rich in sodium chloride, the main salt in blood.
