Are they both called ağustos böceği in turkish?

thanks

I think yes. We call them both ağustos böceği in Turkey. But Cırcır böceği as well. I do not know if there´s a difference between them though. Is there ?

Beware of imposters....Real ones should have violins in their hands..

They are different insects, although both are noisy 

cricket = cırcırböceği

cicada = ağustosböceği
