Do grasshoppers have a complete digestive system?
The digestive system is typical of insects, with Malpighian tubules discharging into the midgut. Carbohydrates are digested mainly in the crop, while proteins are digested in the ceca of the midgut. Saliva is abundant but largely free of enzymes, helping to move food and Malpighian secretions along the gut.
How does a grasshopper digest?

What does the stomach do in a grasshopper?
From the mouth the food passes through the esophagus into the crop. The food is stored in the crop. Next, food moves into the gizzard, where teeth made of chitin grind it up further. Food then moves through the stomach into the intestines
where glands digest the food and other structures absorb the digested food

the grasshopper consists of a brain
and a set of segmental ganglia that together make up the ventral nerve cord. Each ventral nerve cord ganglion develops very similarly during early embryogenesis.
