Cicadas and Their Role in Heralding Monsoon in India


 

1. What are cicadas and why are they significant?
Cicadas are insects known for their distinctive songs produced by males to attract females. They are significant because they emerge annually and their loud chorus is often associated with the arrival of the monsoon season in India, marking a period of rejuvenation and renewal in nature.

2. How do cicadas produce their unique sound?
Male cicadas produce their sound using structures called tymbals, located on the sides of their abdominal base. These tymbals are ribbed membranes that the cicada vibrates rapidly using muscular contractions, producing a loud and piercing sound. This sound can be amplified by their hollow bodies, which act like resonance chambers.

3. What is the lifecycle of a cicada?
Cicadas have a fascinating lifecycle that begins with eggs laid on twigs or grass stems. After hatching, the nymphs drop to the ground and burrow into the soil, where they live and feed on root sap for several years. When ready, they emerge from the ground, molt into adults, and begin the cycle anew.

4. Are all cicadas annual? What about periodic cicadas?
While most cicadas in India are annual, appearing each year, there are also periodic cicadas like the Chremistica ribhoi in Meghalaya, which emerges once every four years. In some parts of the world, there are cicadas known to have much longer cycles, such as the 17-year cicadas in North America.

5. What myths or cultural significance do cicadas hold?
Cicadas have been symbolic of rebirth, transformation, and immortality across various cultures due to their lifecycle and emergence from the ground. In ancient Greece, cicadas were thought to live on dew and air, embodying the idea of spiritual purity. In Chinese culture, jade cicadas were placed in the mouths of the dead to ensure their voice in the afterlife.

These FAQs explore the intriguing world of cicadas, highlighting their biological, ecological, and cultural importance, particularly in the context of the Indian monsoon.
