Why do only female mosquitos bite?
The female mosquito bites humans and animals to get a special protein from blood she needs for nourishment to lay eggs. Male moquitos, you guessed it, don’t lay eggs so they don’t need to bite for blood. They don’t even have the mouth parts for it. The female requires one blood meal for each batch of eggs. If she is not interrupted by a slapping hand, the female will suck two or three times her weight in blood. Her body tells her when she has had enough when stretch receptors in her abdomen sense she has reached her limit. Scientists performed tests where these receptors were deactivated. The females continued to drink until they literally exploded! Male mosquitos dine only on nectar.
