The thorax is covered with scales and has a number of bristles at the rear end. Mating takes place at elevated places like trees, hills and ridges.
Egg laying takes place on host animals, most commonly on hoofed mammals. The larvae always live parasitically in the interior of the host animals (endoparasites). Many species choose specific animals as the host - which body orifice of the host animal is chosen for egg ... | | |

| After mating, the fertilized females lay their eggs in the nests of different bee and waspspecies, for example Heriades truncorum and Ancistrocerustrifasciatus. Occasionally, oviposition takes place in butterfly cocoons, as observed in the case of the small tortoiseshell (Nymphalis urticae). Usually one egg is placed in each nest. Egg-laying often takes place in the nests of solitary bees of the genera Hylaeus and Osmia. A few days later the larvae hatch from their eggs. Firstly they eat the eggs or larvae of the host animals and later on any food supplies found there. | | |

The most striking characteristic of the hoverfly is its ability to remain in one place when flying, even in wind. | | |

|
| The green shield bug does not overwinter in the larva state. Mating and egg-laying take place in early summer. A female lays up to 100 eggs. The larvae hatch and go through 5 phases of development, becoming adults in September. During these phases of development the larvae remain together. | | |

The production of royal jelly takes place in specialized hives/ OR is a specialised form of beekeeping and involves more or less complicated procedures. The royal jelly sold in Germany is largely from China. Due to the fact that the procedure requires removing the queen, and the colony is e... | | |

The young larvae hatch after a few days and start eating the host’s eggs or larvae. Later on they feed on the stored nectar and pollen. Pupation takes place in a cocoon within the host’s breeding cell.

| Female Drosophilidae lay up to 400 eggs in decomposing plant material or in other substrates, which the hatching larvae then feed on. The development of the larvae takes place in 3 stages over about two weeks. The larvae feed on dead parts of plants or rotting fruits. They mainly eat the microorganisms which are involved in the decomposition of plant materials. The larvae of other species are omnivorous and eat their way ... | | |

| When the larvae of the drone flies leave the water they enter buildings in search of a place to become pupae. They are exterminated when they occur en masse. Since the drone fly shows few escape reflexes, it can be captured in the hand. | | |

| Sternorrhyncha live in rural areas and feed on the juices of various plants. While scale insects are not very flexible and usually remain in one place, aphids move relatively freely. Leaf fleas move by jumping. | | |
