How are they different from Crickets?

Grasshoppers and Crickets are similar insects, both being of the order Orthoptera, but they are different and actually are in different scientific suborders. The main differences may be hard to see:
Grasshoppers have shorter antennae than crickets.
Grasshoppers make sounds by rubbing their forelegs against their wings, while crickets rub their wings together.
Grasshoppers hear with their abdomen, while crickets listen with their legs.
Grasshoppers are diurnal (active during the day). Crickets are nocturnal (active during the night).
Grasshoppers only eat plants, while crickets will eat other animals and are omnivorous.
