Gribbly

Funny what you can spot when you are looking around the house. Spotted this 'Gribbly', as we used to refer to pretty much any sort of insect or beetle in the RAF (The insects weren't in the RAF, I was in the RAF).
Not sure what this is, it's not a grasshopper that I know of. Anyway, There's two of them but can't find the second one now. Apart from the dogs they helped to keep Marlane awake most of the night!
