What is the breathing tube of a mosquito called?

• A. Antenna
• B. Proboscis
• C. Maxillary palp
• D. Respiratory siphon

Answer: (D)

The breathing tube in mosquito larvae is called a respiratory siphon. In the larval stage, mosquitoes live in water and must access air at the surface. The respiratory siphon is a tube-like extension at the rear of the larva that projects above the water, allowing it to draw air into its tracheal system while the rest of the body stays submerged. This structure is specialized for gas exchange with the atmosphere, which is why it’s termed a siphon. The other structures have different roles: antennae are for sensing chemical cues and air movement, the proboscis is the long feeding mouthpart used to pierce skin and draw blood or nectar, and the maxillary palps are sensory appendages near the mouth.
