| ...arvae’s hosts. This happens near the brood’s site, which is equipped with food stores. The young Gasteruption larvae hatch after a few days and start eating the host’s eggs or larvae. Later they feed on the stored nectar and pollen. Pupation takes place in a cocoon within the host’s breeding cell. | | |
|
| Mating takes place in late spring or early summer in sunny weather. The fertilized females lay their eggs from the air while clinging to the male (tandem flight). The eggs are attached to plant parts located under the surface of the water. | | |

|
| The larvae develop under water and overwinter there in their final stage of development. During the first three weeks after hatching from their eggs they leave the place where they were born and explore the surroundings of the water’s edges. They then go back into the water. In the following spring they finally leave the water via outstanding plant stems. They free themselves from their larval casing ( exuvia) while... | | |
|
| After mating, which takes place from early June on, the fertilized females lay single eggs into young caterpillars from the family owlet moths (Noctuidae), the species Euxoa tritici and turnip moths (Agrotis segetum) are the preferred hosts. After the larvae of Amblyteles armatori... | | |
|
| In late March, the adult bees of the first generation hatch. The males appear first and fly back and forth over the soil nests on hot days. Mating takes place in April. Immediately afterwards, the fertilized females begin constructing the brood nest in the ground. Nest colonies form/can form, comprising several hundred - up to one thousand - individual nests in a relatively small area. The nests consist o... | | |
|
| Mating takes place in late May to early June. The fertilized females lay their eggs in moist soil. The larvae hatch after several days. Their bodies have velvety black hair. They have strong mouthparts. The larvae of Cantharis fusca live on the ground or near the grou... | | |

| ...ating, the fertilized females lay hundreds of large, light coloured eggs on meat, often on living or dead earthworms. For this reason they also penetrate rooms where meat is stored for human or animal consumption or processing. Egg laying also takes place on open wounds. Meat that has come into contact with such flies should never be consumed by people, for the oviposition of flies carry various pathogens into food. The metabolic products of the maggots are also dangerous. | | |

| ...m moist environments. Most species live in the soil. Others live in the hair of animals, theirorifices or even their skin. Some species specialize in birds and their plumage. Other species are found in the vicinity of people, for example, in beds (place of preference), or upholstered furniture, carpets, textiles, etc. | | |
|
| Mating takes place in summer and afterwards the male spiders live for a short time together with the females in the same web before they die. The females lay their eggs in a cocoon, hidden away and at a distance from the web. | | |
|
| After mating, the fertilized females lay their eggs in stagnant water which is often very muddy. Here, the oxygen content of the water plays a decisive role, as egg-laying can even take place in cesspools. From these eggs the so-called "rat-tailed maggots" hatch – larvae with a long breathing tube attached to the abdomen that extends up to the surface of the water. The larvae feed on decaying organic matter and thus make an imp... | | |
