There are at least 8 to 10 different types of cicadas in the nature and the ones found in the RSC park are large brown cicadas
TIRUPATI: Nature lovers have good news from the Regional Science Centre (RSC), Tirupati.
They could enjoy the Cicadas performing an `orchestra' at the centre.
Cicadas are insects (Phylum: Arthropod) which make special sounds using the organs inside their abdomen.
Muscles and membranes at the bottom of their abdomen produce the sound.
As the muscles vibrate the membrane produces the sound.
It's a haven
According to a note circulated by the RSC, the sound is echoed inside a cavity in the abdomen which would act as an amplifier to make the sound go louder.
The Science Park in the RSC during June and July turns a heaven or a haven for the wild cicadas which with their `jee..jee..' humming try to attract their female companions for mating.
There are at least 8 to 10 different types of cicadas in the nature and the ones found in the RSC park are large brown cicadas.
