LOCUSTID/E. 



The Locustidae have been called in some of the books, locusts because of 

 the family name and sometimes grasshoppers because of their grass-green 

 color Most of the males have the vikings modified into musical organs and 

 the best known species is called katd-did because of its song and this name 

 has come to be used for the whole group. Many of the California species are 

 wingless and therefore voicless.. Ous largest forms are locally called "potato 

 bug."
