What life stage of mosquitoes does not feed and is active only if disturbed, also known as the tumbler stage?

The tumbler stage refers to the pupa stage of mosquitoes. At this life stage, mosquitoes undergo transformation and do not feed, relying on stored energy from earlier stages. Pupae are semi-aquatic and exhibit a characteristic tumbling action when disturbed, which helps them to avoid predation.

The pupa is a critical stage of metamorphosis, transitioning from the larval stage into the adult mosquito. During this time, they are not actively feeding, which distinguishes this stage from the larval stage where feeding occurs extensively. Their movement is primarily a response to disturbance, allowing them to remain somewhat concealed in their aquatic environment.

In contrast to the pupa, the egg and larva stages involve feeding and development, while the adults are active and have different behaviors related to feeding and reproduction. Understanding the characteristics of each life stage is essential for effective mosquito control and public health strategies dealing with vector-borne diseases.
