| Eupteryx aurata prefer habitats with rich vegetation. This also includes water edges with herbaceous vegetation. They feed by sucking plant juices from single cells of leaf tissue (mesophyll). Tiny white spots can then be seen on the leaves as the saliva of Eupteryx aurata destroys chlorophyll. Their preferred food plants include nettles (Urtica), Labiatae (Lamiaceae) and potato (Solanum tuberosum). | | |

| The Nigma walckenaeri is the largest species of Dictynidae in Central Europe. While the females reach body lengths of 4. 5 - 5. 0 mm, the males are 3. 5 - 4. 0 mm in length. They have small groups of white hairs all over their bodies. The front section of the female’s body is yellowish brown to yellow, and the male’s is reddish-brown to brown. The male’s head appears posited markedly higher. The central eyes of these spiders are remarkably small. The ... | | |

| After mating, the females erect a cocoon for the eggs. The white cocoon is 6 - 7 mm in length and is hidden, at a slight distance from the hideout of the spider. After reaching maturity (after the last moult) the life expectancy of the males is very short, and most die shortly after mating. | | |

| Their bodies have bizarre shapes. Their indentations, spots and stripes, as well as their colouration, help them to camouflage themselves. Their colouration ranges from snow white with red stripes, to pale green, brown, bright yellow or emerald green and they are often attractive looking. The body surface can also be longitudinally striped or spotted. Diaea dorsata usually live on leaves, while colourful species are found on ... | | |

| ...wn in colour, with spots and irregularly distributed pits. The underside of the body is light coloured with dark spots. Between the front hips (on the 1st sternite) is a long crescent-shaped spike. The antennae are predominantly black with yellowish-white stripes on the 3rd to 5th segments. The 2nd segment is longer than the 3rd. The mouthparts form a proboscis. | | |

| ...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 dotted. The wing covers usually have dark brown patches of colour. Rhaphigaster nebulosa are clumsy fliers and buzz loudly in flight. | | |
|
| After mating in late spring, the fertilized females lay about 40 eggs on plant parts. The eggs are initially yellowish-white, later brown, about 1. 5 mm in length, and are glued to stripes and disc formation. The hatched larvae (nymphs) are a variety of colours and have no wings at first. These grow from the 3rd larval stage on (after the 2nd moult). The young bugs have t... | | |

| ...engths of 12 - 15 mm. Their wings have spans of 22 - 28 mm. The upper surface of the wings is dark brown in colour. The edges of the wings are orange spotted. The underside of the wings is grey-brown with orange spotted and black areas surrounded by white rings. | | |
|
| Adult Eristalis lineata reach body lengths of 11 - 15 mm. They resemble bees. Their faces are covered in white hair, which is divided by a stark black central line. There are also long hairs on their antennae. Eristalis lineata can be confused with Eristalis interrupta. | | |
|
| After completion of the nests, the eggs are laid, one in each breeding cell. After 2-3 days the white maggot-like larvae hatch, and are fed with captured honey bees by the mother. The female larvae clearly receive greater consideration than the males. The larvae live inside the body of the bees. After each flight for new supplies of bees the mother ... | | |
