The knob-like structures located directly behind the wings of a mosquito are known as halters. These organs are specialized modified hindwings that serve an important function in aerial stability and balance during flight. Halters detect changes in orientation and rotational movement, allowing mosquitoes to maintain control and perform agile maneuvers while flying. This adaptation is crucial for their survival, especially when navigating through their environments and avoiding predators.

Hindwings are commonly the name for the second pair of wings in insects, but in mosquitoes, they are transformed into halters and no longer serve a traditional wing function. Ocelli are simple eyes found in some insects that aid in light detection but are not related to balance. Maxillae are mouthparts used for feeding, contributing to the mosquito's ability to draw blood or feed on nectar, but do not play any role in balancing the insect during flight.
