Haltere

Definition

A small knobbed structure modified from the hindwings of flies (Diptera) that functions in maintaining balance during flight through the detection of body rotations.

Etymology

From Greek 'haltēres', meaning 'weights used in jumping', due to their resemblance to exercise weights.

Example

The halteres of a housefly vibrate as the insect flies, providing sensory feedback to help stabilize its flight.

Usage Notes

Halteres are unique to flies and are crucial for their ability to perform agile maneuvers in the air. Their function is analogous to gyroscopic instruments in aircraft, aiding in stability and orientation.
