Which anatomical feature is NOT part of mosquito anatomy?

The anatomical feature that stands out as not being part of mosquito anatomy is the presence of two pairs of wings. Mosquitoes are classified as dipterans, which specifically means they only possess one pair of functional wings. The second pair has evolved into small halteres, which are not used for flying but serve as balance organs during flight.

On the other hand, mosquito anatomy includes an elongate proboscis, essential for feeding, allowing them to pierce the skin of their hosts to extract blood. They also have a slender thorax, which is characteristic of their body structure, enabling agile movement while flying. Additionally, mosquitoes have three pairs of legs, providing them with the necessary mobility on both surfaces and in flight. Each of these features plays a crucial role in their survival and adaptability.
