Johnstons organ

The Johnston's Organ is located in the second segment of an insect's antenna. Sound waves vibrate the antenna of the insect and these vibrations are detected by the Johnston's organ. The Johnston's organ is commonly used to find a mate as an insect can detect the sound of wing beats of a mate.

It is the presence of the Johnston's organ that separates insects from the non-insect hexapods.
