| Bot flies | ...large wings have a central vein spreading out in different angle. 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 laying also depends on the species. The hatching maggots (larvae) develop accordingly in the nasal mucous membrane, the throat or beneath the skin (subcutis) of their host animals. Egg laying can be a risky business for some females as the larvae hatch very fast and can attack their own mothers.

...ery fast and can attack their own mothers.
The approach of Bot flies can cause panic reactions in in cattle which often sustain severe injuries by running away into fences or barbed wire. The migration and development of larvae inside the host animals inevitably leads to illness and sometimes to the host animals’ death. The larvaes’ stay in the host animals can last as long as several months. In their last larval stage the maggots leave the host animal and fall down to the soil to pupate.

The females lay their eggs in the nostrils or eyes of sheep. The larvae hatch from their eggs inside the females and are shot into the host animals in drops of liquid. The host animals resist this. The laying of the maggots must be done quickly, otherwise the mother will be attacked by her own brood. The larvae, approximately 500 in number, nest in the nasal cavities and sinuses of the sheep, remaining there for months. In th...
...must be done quickly, otherwise the mother will be attacked by her own brood. The larvae, approximately 500 in number, nest in the nasal cavities and sinuses of the sheep, remaining there for months. In the spring of the following year, the host animalsalready show symptoms such as sneezing and inflammatory discharge.
The larvae are up to 30 mm in length. After the last larval stage, the larvae are sneezed or coughed out by the host animals and fall down to the soil in which they pupate. The sheep bot fly occasionally lays its larvae in humans, especially in the eyes.

In addition, they nourish the seeds of the black locust. In addition the animals suck stems and leaves of herbaceous plants, sometimes on eggs of insects, dead insects and vertebrates. Cannibalism in these animals also is possible. | | |
| | The German wasp nests underground. Construction begins in spring. The wasps often nest in spaces previously used by other animals which are then expanded. The colony 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 i... | | |

This includes caterpillars, beetles (larvae and adults) and the larvae of various Diptera and arthropods. The larvae of the tachina flies enter their host animals in different ways. Firstly through ingestion of their eggs, secondly through oviposition directly on the host animal, or thirdly through the hatched larvae’s direct entry into the host animal. Usually the host animals die before the larvae’s development is complete. The pupation of the larvae usually occurs outside the host animal.
Since the larvae of many tachina flies kill pests, they are very welcome in the agriculture and forestry industry. | | |
| Female Scatopsidae lay their eggs on decaying animals or vegetable waste and can thus be found on compost heaps, dung, in toilets, on garbage heaps and so on. They also often appear on or in buildings such as dwellings, sheds or storage facilities. When they appear en masse, they can make food supplies...
...ompost heaps, dung, in toilets, on garbage heaps and so on. They also often appear on or in buildings such as dwellings, sheds or storage facilities. When they appear en masse, they can make food supplies inedible due to germs and impurities such as animals and human beings are a nuisance and are thus considered a nuisance by humans. The larvae are social and feed on rotting waste materials. They are found under bark, in dead wood, fungi or feces, according to what species they are. Some species live a... | | |
| | Arachnids | | Arachnology is the science of arachnids (Arachnida), while Acarology is concerned only with animals with a spider-like appearance. Arachnids belong to the category of Arthropods (Arthropoda) and can be classified as spiders, whip spiders, Solifugae, hooded tickspiders, harvestmen, Acarina and ticks. The largest order within the arachnids are the A... | | |
| | Common to all wasps is the black-and-yellow warning colour of the body. The Vespinae live in states or parasitically as so called cuckoo wasps. Adult Vespinae mainly feed on small parts of dead or living animals, from insects, pollen, plant juices and from nectars. Their larvae are mainly fed on animal meat.

In the period up to August the population of the colony grows from 60 to 150 animals. During the months of September and October the colony (with the exception of the queen) dies. | | |

The dietary habits of rove beetle larvae are generally the same as the adults. While most rove beetles are predatory some species eat fungi, or putrescent animals and plants. The larvae of some species live as parasites? on the pupaeof flies. There are species of rove beetle, which only inhabit birds' nests, mammals' nests, ants' nests, termites' nests or those of wasps. In ants' nests, rove beetles hunt fo... | | |
