Meet Cicada - The loudest insect in Indian Forest
If you have been on Tiger safaris in Central India during summers, you already are familiar with the sound – a loud, continuous, high-pitched buzzing siren that seems to come from everywhere. This hum belongs to one of the smallest but loudest residents – the Cicada aka Jhingur. They are winged insects best known for their high-pitched calls made exclusively by males. And that sound has one purpose - to attract females. It's a mating call, amplified to a volume that seems unreasonable. But that’s how they express and propose their love.
Frequently Asked Questions – About Cicada
How do Cicada’s make so much noise?
Inside the male's hollow abdomen lies a natural resonance chamber that acts like an amplifier. The anterior region of the abdomen has exoskeleton structures comprising - membranes and ribs which are known as a tymbal. They can contract and relax the powerful internal muscles which buckle the tymbal producing clicks back and forth. When these clicks occur in rapid succession, they merge into continuous, piercing buzz that echoes through the forest.
What is the lifecycle of Cicadas?
After mating with the male, the female deposits her eggs into the bark of a twig. The newly hatched nymphs from the egg drop out from the bark and lay underground feeding on the sap of roots. The nymph has strong front legs for digging and during their final stage called ‘instar’ emerge out to the surface and molt on a nearby plant. After molting, they abandon the exoskeleton called ‘exuvia’ and come out as an adult.
How long do cicadas live?
Most of a cicada's life varies from 2 to 4 years and is spent underground as a nymph feeding on root sap. Adults live only a few weeks after emerging.
What is Cicada spray or Cicada rain?
Cicadas feed on tree sap, which contains large amount of water but relatively few nutrients. To obtain sufficient nourishment, they consume large amount of sap. Since most of this liquid is excess water, they continuously expel it through their anus as tiny droplets. On hot summer, beneath large trees with numerous cicadas, visitors experience this light drizzle also referred as Cicada rain or spray.
