| Common woodlouse | | ..., America, Africa and Asia. Common woodlice reach body lengths of 15-18 mm. They are dark grey to blackish-brown in colour. They have two longitudinal rows of bright spots on their backs and bright coloured. appendages with punctiform openings (defensive glands) on their sides. They have lobes on the sides of their heads at eye level.
The common woodlouse lives among fallen leaves, in rotting wood, under stones and under the surface layer of medium moist soil in deciduous forests and bushes. ... | | |
| | ...ion of the abdomen’s upper surface changes seasonally and has green, brown and reddish tones. The head, pronotum and scutellum are covered in black dots. The keel of the abdomen’s roof shaped underside has a sting-like appendage. Beside the legs are defensive glands, which produce secretions with an unpleasant odour, when there is a threat from their natural enemies (i. e. birds).

| | On the underside of the chest (thorax) are the defensive glands which emit an unpleasant-smelling secretion as a defense mechanism. This can be squirted over a distance of several decimetres. The abdomen is black at the edges (connexivum) and has yellowish-white markings. The side margins are densely dott... | | |
| | There is a single defensive gland on the underside of the posterior segment of the chest (metathorax) which can release a very unpleasant-smelling secretion. There are 3 to 5-yellowish-white granules at the front edges of the scutellum. The abdomen is almost completely covered... | | |

A key identifying characteristic for both species is the shape of the orifice of the defensive gland outlet. In the southern green stink bug it is short and wide, and in the green shield bug it is elongated and oval. | | |
