What is a pupa stage mosquito commonly known as?

The pupa stage of a mosquito is commonly referred to as a tumbler. This stage is characterized by its distinct shape and behavior in the water. Unlike larvae, which are more active and "wiggle" around, pupae have a more rounded body and are generally less mobile. They tend to float just below the surface of the water and can be seen tumbling or rolling when disturbed, which is where the name "tumbler" comes from.

In contrast, the larval stage is commonly known as a wiggler because of its active swimming motion. The terms "swimmer" and "wiggler" do not accurately reflect the characteristics of the pupa stage. Therefore, the correct association of 'tumbler' with the pupa stage highlights its unique anatomical and behavioral features during this critical phase of its life cycle.
