Some of the Arabs are stated by Niebuhr, to 

 preserve large quantities of these insects in the 

 dried state, for winter consumption. 



The Grylli feed exclusively on vegetables. 

 They fly with a considerable strength of wing, 

 and some species make a noise when they poise 

 themselves in the air, previously to alighting, by 

 striking the hemelytra together. During their 

 several changes, they continue active and vora- 

 cious, and their gait is always either a leap or a 

 walk. In the larva state, they are destitute of 

 any appearance of wings or hemelytra, but on 

 changing to the pupa, they gain the rudiments of 

 those members, to be completely developed at the 

 next change.
