Answers below are taken from the article’s stored facts, so they match what the student read.

1. What is the scientific classification?Halteres are homologous structures found in the insect orders Diptera and Strepsiptera
2. What is the biomechanical principle?Function as vibrating gyroscopes, utilizing the Coriolis effect to detect angular acceleration
3. What are halteres and what do they do for flies?Halteres are tiny, club‑shaped structures that act like gyroscopes. They help flies keep balance and steer while they fly.
4. Why did flies turn their hind wings into halteres?Flies evolved halteres from their hind wings so the front wings could focus on pushing air. This change gave flies better control in the air.

Homologous Structures: Structures in different species that share a common ancestry, even if their functions differ.
Angular Acceleration: The rate at which an object's rotational speed changes.
Mechanosensory Organs: Sensory receptors that respond to mechanical stimuli such as touch, pressure, or vibration.
