| Chrysoperla camea s. l. | | ...s a year. The adult insects are usually active at twilight and feed on pollen, nectar and honeydew from aphids. During the day they sit, hidden, under leaves. They overwinter in places where they are well hidden from other animals and insects. Their larvae are considered beneficial as they eat aphids (up to 10 per day) and aphids are viewed as pests in agriculture. In 1999, the Chrysoperla camea s. l. was declared Insect of the year. | | |

| Wool Carder Bee / Leafcutting Bee (Anthidium manicatum) | | ...s build individual cells for their eggs using pieces of leaves bound together by a substance they secrete. They then supply each cell with pollen or nectar, before introducing an egg into the cell. After egg-laying the cell is sealed. When the larvae hatch, they live on the pollen and nectar for weeks before pupating. The Anthidium manicatum reproduces once a year. The females are active from June to October, the males from June to September. On rainy days the animals take refuge in safe, ... | | |

| The larvae are looking stretched long, often soft and velvety dark colored. They feed on small insects and snails and live on the ground. | | |
|
| .... Some species hide their eggs in holes in leaves, stems or twigs. Others cover their eggs with feces. The Donaciinae live both on water as well as on water plants. Here is the egg laying in a kind of jelly. The eggs are laid in rows on leaves. The larvae bore their heads in roots, stems or leaves and suck out the plant juices. | | |

| Dor Beetles - Earth-boring dung beetles | | ...nsects wear horns, humps or have deep impressions on their large and curved necks.
The earth-boring dung beetle lives in forests, steppes and fields.
The adult beetles are active during the day and night. They are clumsy in flight. Adults and larvae feed on faeces, rotten plants and fungi. Some eat leaves, others do not apply to food.
Dung beetles dig complex underground systems of passages (often beside dung). The young are fed and taken care of in individual chambers. | | |

| Dune robberfly | | ...or their prey which they catch and sting in the air.
The dune robberfly is active from June to September. The females have a ring of spikes at the end of their ovipositors which they use to make a hollow in the sand to lay their eggs in. The larvae usually move deeper into the sand after hatching. | | |

| ...ide ; the female brings pollen and nectar here and lays an egg. She then seals the cell with chippings which she glues together with her saliva. In the direction of the exit the female then builds a new cell and then another and so on. When the larvae hatch they are like maggots and they develop for 3 weeks. They then turn into pupae and finish their development in June. | | |
|
| ...While the Nematocera have a bad reputation amongst humans because their bites can be painful and can cause allergies and transmit germs, the crane fly (larval stage) is regarded as a useful animal, because the diet and elimination behaviour of the larvae help to improve the soil. | | |
|
| ...lony usually comprises 3000 to 4000 animals. Even nests of 7000 wasps are not uncommon. The nests can have a circumference of 2 meters. The division of labour is organised in the colony. The intensity of the brood care is like that of the bees. The larvae of Vespidae are fed on the meat of insects. | | |
|
| ...us are active from June to August, mainly on pastures. They can be recognized by their clearly audible hum. The females suck blood, mostly from horses and cattle.
The females lay their white, oblong eggs on plants in disorderly piles. Their larvae are whitish-green. They live in the soil and feed on rotting parts of plants and small organisms, which they kill by injecting them with poison, using their mouth parts.
Tabanus sudeticus are considered to be disease carriers, particularly of the... | | |
