Introduction: The Cicada and Its Anatomy

Cicadas are fascinating insects that are known for their loud and distinctive songs. These insects belong to the family Cicadidae, which is made up of approximately 3,000 species. Cicadas are known for their unique anatomy, which includes specialized structures for producing and detecting sounds. In this article, we will explore the anatomy of cicadas, with a particular focus on their ears and how they locate sounds in their environment.

The Ear Structures of Cicadas

Cicadas have two types of ears: the tympanic membrane and the Johnston’s organ. The tympanic membrane is the primary hearing structure of cicadas and is located on the front legs of the insect. This membrane is a thin, circular membrane that vibrates in response to sound waves. It is connected to a complex system of nerves and muscles that allow the insect to detect and process sounds. The Johnston’s organ, on the other hand, is a secondary hearing structure that is located in the abdomen of the insect. This organ is responsible for detecting low-frequency sounds and is particularly sensitive to vibrations.
