Acrida, Duronia chloronota, Cymochtha prasina
Behaviour:
The wings of both Acrida sp. and D. chloronota also produce a noise when the grasshoppers are in flight. The wings of C. prasina, on the other hand, although appearing to vibrate very rapidly are remarkably silent and the flight resembles that of a fluttering white moth. [1]
