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).
