| The andromeda lace bug can multiply in large numbers and appears en masse. The bugs cause mottling on the leaves of plants. Egg-laying is carried out with the aid of an ovipositor. The eggs are very small and transparent and are sunk deep in the leaves’ tissue (usually on the underside). The eggs overwinter there. | | |

| ...heir glands which make their surface look powdered. The development of the larvae takes place in 5 stages and takes 20 to 70 days depending on climatic conditions Flying larvae are rarely seen. The larvae are not very eager to move and often hide in small cavities or between parts of plants, and when disturbed, show little inclination to leave. The andromeda lace bug is primarily regarded as a crop pest by humans. | | |

| ...ted. The upper side of the body is bare and shiny. Half blankets and neck shield have a dark brown to black hue and the centre and tips of the wings bear patches of yellowy - red. On the upper side of the insect is a yellow mark in the shape of a small heart. These bugs have large complex eyes. The head and legs are lighter in colour than the rest of the body. There are dark patches on the legs. | | |

| ...he females. The females reach body lengths of 6-10 mm, the males, 6-8 mm. The front section of the females’ body (prosoma) is either beige-brown, tan or brown in colour. The sternum is dark brown to black, and sometimes has a dark edge. There are small bright spots beside the hips (coxes). | | |

| The Tetragnatha montana is the only species where the female has a small tooth near the root of its mouth parts (chelicerae). The rear section of the females’ body (opisthosoma) is a shiny silvery white colour on the upperside. In the middle is the characteristic leaf-like marking (folium). It is composed of a white... | | |

| The adult (mature) Tetragnatha montana appear in the open from May to September and the earliest are already visible in February. They feed on flies and mosquitoes. It is for this purpose that they build small orb-webs (an upright web formed of threads radiating from a central point, crossed by radial links that spiral in from the edge) between branches and stems. The Tetragnatha montana lies stretched out, outside its web, waiting for the prey. If an ... | | |

| These are relatively small moths with slender, elongated bodies. They can reach body lengths of 10 mm and wingspans of 10-15 mm. Their wings have a metallic sheen and are various shades of brown in colour with slightly raised, white stripes. The front wings have 12 veins,... | | |

| ... lengths of about 10 mm. The body surface is finely ridged, pale yellowish-green to whitish-green, sometimes translucent, and therefore darker in the front half because here the internal organs show through the skin. Their breathing holes are very small and have a brownish periphery. The head is light brown. The head’s capsule has brown and black spots. | | |

| The larvae of the phantom midges live (standing vertically) in water. Their body is transparent (glass rods larvae). They have antennae, which are also shaped in such a way as to function as holding devices for the capture of small insects (eg mosquito larvae) or crustaceans (eg Daphnia). The antennae are used to impale the prey, to crush it and to guide it into the larvae’s mouth. | | |

| ...00 species in total, 570 of which occur in Germany. Some species of the genus Clunio are only found on the surface of the sea. Belgica antarktica are found solely in Antarctica. Most species of Chironomidae reproduce once a year. Chironomids are small to medium in size and reach body lengths of 2-14 mm. They have slender bodies and are soft-skinned. | | |
