Why is the Limpsfield area overrun with grasshoppers?

You may (or may not) have noticed that the area around Limpsfield has a recurring motif – the grasshopper.  This chirpy little critter has given its name to The Grasshopper Inn and Grasshopper on the Green in Westerham and to the local youth team of the Limpsfield and Oxted Cricket Club. It also features as the emblem of Titsey Manor (The Titsey Crest),  Botley Hill Farmhouse, The Limpsfield Chart Golf Club and the Limpsfield Decorative Fine Arts Society!
