How do mosquitoes suck blood?



Did you know that the living things you see everyday have very interesting features? Yes, mosquito is what I’m talking about. It’s a common insect of every family. As you know, mosquitoes bite our skin, suck our blood and leave us itchiness. They suck blood by piercing your skin with their tube like a mouth called stinger and inject their saliva into your blood which prevents clotting in the area of the bite. Later, your body has a small allergic reaction to the saliva. Like any allergic reaction, your body can get used to it over time, so children often have worse reactions to mosquito bites than others do, and if you travel to a new place with different kinds of mosquitoes, you may get worse reactions there than you do at home. In fact, males typically feed on nectar and plant juices, the female needs to obtain nutrients from a blood meal before she can produce eggs. Their life span can be 1-2weeks, so during that time female mosquitoes can mate with males and give birth to their babies. Next time where ever you are, try not to be their victims!
