Question

These insects produce a chirping sound by rubbing their front
Wings together​

Answer 1

Answer:

The katydids and crickets, both of whom could be considered as cousins of grasshoppers, chirp by rubbing their two hind wings together. The katydids are so named because they seem to be calling out 'katy-did, katy-did' all day. The noisiest of all insects are the cicadas.
