Mosquitoes drink blood using a sophisticated mouthpart called a proboscis.
The Mosquito's Proboscis
The proboscis isn't just a single needle; it's actually a complex system consisting of six thin, needle-like structures known as stylets.
Stylet Function
- Piercing: The stylets work together to pierce the skin.
- Blood Vessel Location: These stylets are adept at finding blood vessels.
- Sucking: Once a blood vessel is located, the mosquito uses its stylets to efficiently suck blood.
The mosquito's mouth, also called a proboscis, isn't just one tiny spear. It's a sophisticated system of six thin, needlelike mouthparts that scientists call stylets, each of which pierces the skin, finds blood vessels and makes it easy for mosquitoes to suck blood.07-Jun-2016
Mosquito Blood-Feeding Mechanism
| Step | Description |
|---|---|
| 1 | The mosquito lands on the host's skin. |
| 2 | The six stylets of the proboscis pierce the skin. |
| 3 | The stylets locate a blood vessel. |
| 4 | Blood is drawn up through one of the stylets. |
| 5 | The mosquito ingests the blood, filling its abdomen. |
Why Mosquitoes Need Blood
Only female mosquitoes drink blood. They need the protein in blood to produce eggs. Male mosquitoes feed only on plant nectar and other sugary substances.
