        What is a grasshopper?


        Grasshoppers, locusts, crickets and katydids are all insects belonging to the
        group Orthoptera, but how can you tell them apart?

                               Like all other grasshoppers, they have very long hind legs
                               and the ability to jump. What’s more, scientists say they
                               use their compound eyes to detect gaps, allowing them
