Final answer:
The pupa of a mosquito is aquatic, while the pupa of other insects is not.
Step-by-step explanation:
One difference between the pupa of a mosquito and the pupa of other insects is that the pupa of a mosquito is aquatic, while the pupa of other insects is not.
When a mosquito larva reaches the pupa stage, it transforms into a comma-shaped pupa that lives in the water. The pupa is immobile and hangs from the water surface using a pair of respiratory trumpets. In contrast, the pupa of other insects typically undergoes metamorphosis outside of the water.
For example, the pupa of a butterfly is usually enclosed in a protective case called a chrysalis, which is attached to a surface like a plant stem or branch.
