Locusts, grasshoppers (mostly Acrididae and Pyrgomorphidae), crickets (Gryllidae) and katydids (Tettigoniidae) are insects of the order Orthoptera. Many are edible and more than 80 species of locusts, grasshoppers and crickets are consumed worldwide for human food in Africa, South America and Asia. They may be part of the normal diet, or delicacies sold by street vendors.
A grasshopper is active in the day and a cricket is active in the night. Crickets and grasshoppers look similar, but there are differences. A big difference is that they belong to different families. The grasshopper is an insect of the suborder Caelifera in the order Orthoptera. Crickets, family Gryllidae, are insects somewhat related to grasshoppers and more closely related to katydids or bush crickets (family Tettigoniidae).
