| Due to their appearance, Philodromus aureolus can very easily be confused with Philodromus cespitum and Philodromus buxi. A definite identification is possibleonly by checking the shape of the genitals. | | |
|
| Adult half-spotted stink bugs reach body lengths of 10 - 15 mm. The body is black and red in colour. The pronotum is red with black edges and bears 10 black spots, which vary in shape and sometimes converge. The edges of the abdomen (connexives) have stripes lengthwise. The underside is spotted black. Half-spotted stink bugs can be confused with Graphosoma lineatum or Graphosoma italicum. | | |

| ...ma of the males is dark brown to black, has short hairs and a clear white stripe on both sides. The upper surface of the rear section of the body (opisthosoma) of the females is light brown to brown with dark edges. In the middle, an indistinct leaf shaped pattern (folium) is usually visible. Towards the back of the abdomen is a marking in the shape of an arrow or angle. Brown spots can sometimes be seen on the front of the abdomen. The sides are white to cream-coloured or light yellow, with the edges clearly separated. | | |
|
| ...he southern green stink bug can be confused with the green shield bug (Palomena prasina). The latter is about 1 mm smaller and has no clear grainy boundary at the front edges of the scutellum. 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. | | |
|
| The larvae (nymphs) of the southern green stink bug hatch after 5 days in summer, or after 2 to 3 weeks in spring. They develop from egg to adult bug within 35 days. They have colourful bodies. Their markings and shape changes after each moult. In the first larval stage (which lasts 3 days), they remain sitting in groups next to their empty eggs without eating. In this way the tiny larvae can combine the power of their defense secretions and thus ward off their pr... | | |

| ...ead, thorax, antennae and legs are now black. There is a yellow patch on each outer side of the upper surface of the chest. The abdomen is red, as are the 2nd, 3rd and 4th segments of the antennae. In the 3rd and 4th larval stages (7 days), the body shape changes and shades of green start to predominate in the colouration. In the 5th stage (8 days) the wings begin to grow. The abdomen is yellowish green now and has red spots on its axis in the middle. During the 8th day the final moult occurs and the... | | |

| The head is is elongated at the front. The first two segments of the antennae are black, the third is yellowish-brown. The 2nd segment is ovoid to roundish in shape. The area between the eyes is whitish-yellow or yellow and is broken up by a grey-yellow central line. The compound eyes are positioned at a distance to each other. In the males this distance is just wear slightly smaller. | | |
|
| Adult Anthrenus pimpinellae reach body lengths of 2 - 4. 5 mm. Their bodies are relatively small and oval in shape. The upper surface is covered with scales and has a black base colour. The antennae have eleven segments, the last three of which form a club. The pronotum (neck plate) is covered with reddish-yellow and white scales, with darker patches in the midd... | | |
|
| The abdomen (opisthosoma) is narrow, arched and tapers to the rear. The upper side is yellowish brown and has a fine, dark, pattern. In the middle is a bright marking in the shape of an oak leaf, hence their name. The upper leg (femur) is brown in colour, while the lower limbs are ringed with narrow, bright and dark bands. | | |
|
| The oak spider spins its web near the ground, between bushes or corn stalks with the hub is covered by a dense white tissue. The spider itself sits in another web, which has a bowl-like shape, is open upward and attached near to the upper edge of dry plant parts, or even larger flowers. If there is interference or danger the oak spider may fall to the ground, returning to its observation post after some time. | | |
