| Fertilized females lay their eggs in flight, on sedentary or slow-flying hosts (bees, bumble bees or wasps). The larvae hatch and burrow into the abdomen of their host animals and feed on their insides until they are completely empty. They pupate and overwinter in the empty skin of the host. During the following spring, 8 - 10 months after hatching from their eggs, the adult flies emerge from the pupae. | | |
|
| The scoliid wasp larvae hatch after about 1 week, under favourable conditions. For 1 - 2 weeks they feed on the body fluids of the host larvae and from the 4th larval stage on they eat the rest of the host larvae. After their last larval stage, scoliid wasps pupate in cocoons, which are often reddish to brown in colour. The Scoliidae larvae of most ... | | |

| ...ctober, it occurs more frequently and is found in various habitats. They occur in particularly large numbers everywhere where old, rotting meat or faeces can be found. The adults often sit on trees, shrubs and herbaceous flowering plants, where they feed on nectar, sweet plant juices, ripe fruit juice or honeydew from aphids. However they also like the protein-rich fluid from dung or carrion. Some of the adult flies overwinter. | | |

| ...agma ocellaris prefer moist habitats such as deciduous forests, swamps or wet meadows. They are active in May and June and from September to April and suck blood.
Their larvae, which probably develop in the soil, have hairy pseudopods (feet). They feed on parts of decaying plants. | | |
|
| They build nests in the ground for their eggs and the developing offspring. Therefore often serve them cavities in the soil. Inside the nests they erect breeding cells for their larvae. The hatched larvae feed on spiders captured by the female spider wasps. Some species build nests in human dwellings. Others are parasitoids, living in other spider wasps nests. In the latter case, the female lays its eggs inside a dead spider, which just gets carried into ... | | |
|
| When the rubytail wasplarvae have hatched, they (after having scoured the aisles of the nest of food competitors) feed on the eggs or larvae of their hosts. Rubytail wasp larvae always hatch before their host’s larvae. Approximately 14 days after the rubytail wasp larvae hatch, even the food supplies of their hosts (only insects, no pollen) have been consumed, and t... | | |
|
| The females lay their eggs in almost any appropriate water, regardless of the volume. The larvae of the mosquitoes develop under water. They get oxygen from the water surface, through a proboscis, which is located at the back end of the body. They feed on microorganisms and sometimes prey on other mosquito larvae. | | |
|
| 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) a... | | |

| ... They reach lengths of up to several centimetres later. Tipula oleracea have a life expectancy of 8 months and usually produce 2 new generations a year. The first generation is active from April to June, the second from August to October. The adults feed on nectar or water. | | |
|
| The females lay the first generation of eggs in spring in loose, moist soil or in damp meadows, in gardens or in cultivated land. The eggs are oval and about 1 mm in size and can number up to 1, 200. The larvae hatch after 15 days and feed on fallen leaves or on the roots of young plants. They can cause considerable damage in horticulture and agriculture. 300 to 400 larvae per square metre of usable area is not uncommon. The larvae pupate in the soil about 4 months after hatching.
