The grasshopper's abdomen is free of appendages except for those at the posterior end.
These are used in mating and egg-laying. Because of the relatively small head and
muscular thorax, most of the grasshopper's bodily functions are controlled in the
abdomen. It contains the digestive tract which is divided into three parts: the
fore-gut, mid-gut and hind-gut. The fore-gut actually starts at the mouth and
runs on as a narrow oesophagus which, in turn, leads to the crop. The crop is a
large sac in the thorax that serves as food storage that the grasshopper can enjoy
at its leisure. The crop is lined with spiney ridges which serve to shread the food.
The mid-gut is also the stomach. They're the same thing. It lies mostly in the abdomen.
