Update: Thanks once again to Gary Francis over at Back Garden Moths site for the ID on this one, although its difficult to be 100% on it, this looks most like the Emperor Moth Caterpillar in the 3rd Instar stage. If any one finds this and disagrees I'm happy to hear any other possible ID's. Need ID Please :) Not sure the food plant here, but found in Filsham Reed bed area, in East Sussex.
