Green Shield Bug (Palomena Prasina)
Young larvae are green with a lot of black. Older larvae are plain green.
Family: Stink Bugs (Pentatomidae)
This species is not called Green Stink Bug for nothing. First of all it is green indeed and secondly it produces a stinking liquid. That's why it is such an unwanted animal. It not only produces this perfume when in danger, like lady beetles do. Everywhere it goes it leaves behind a stinking trail. You often notice this picking blackberries. Suddenly you pick a smelly one, tasting awfully when eaten. Usually a Green Stink Bug was there before you were. Green Shield Bugs have only very few natural enemies. It is a very common species all over the British Isles and on the continent as well.
