Dark Bush Cricket

This chap appeared on the back of one of the kitchen chairs on Saturday night, obviously keen to find its way to the sofa to watch one of the most memorable games of rugby ever played: England v Wales at Twickenham in the World Cup. Wales built from weakness, through adversity, to strength and final domination to beat England 28-25. It was an extraordinary match which took me back to my youth, supporting Wales at Cardiff Arms Park. 
You can tell he's a he due to the lack of ovipositor (the large, sickle-shaped thing that sticks out of the end of the female). He's a Dark Bush Cricket, Pholidoptera griseoaptera.
