Cimbex femoratus
Another very large Sawfly, Cimbex femoratus is more commonly known as the Birch Sawfly, which although still given the status of being common, is believed by some people to have declined over recent years. The large caterpillar-like larvae feed on Birch and are conspicuous, with the one photographed being found on Budby South Forest in early August 2009. The adult was found in an injured state at Sherwood Forest CP by ranger Gary Joynt.
