| 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.

| Bot flies | | ...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... | | |

| Taurus fly | | ...mber of eggs (located singly or in or in small clusters) can amount to more than 1000.
The larvae are very small when they hatch. At the end of their abdomen is an apparature through which they can move like loopers (inchworms). The larvae feed parasitically on spiders or on their young. They jump on approaching spiders and penetrate (through the skin at one of the spider’s joints) into the prey’s body. They remain here and feed slowly on the spider’s insides until the end of their larval stage. Th... | | |

| The larvae of velvet ants live parasitically in the nests of Aculeata, where they consume both the larvae of the hosts, as well as their food (nectar and pollen). Adult velvet ants are active from May to October in different habitats. In midsummer, they are often encountered en masse. | | |
|
| The life span of the adults is often only a few days. The larvae live within almost all parts of plants. Some species inject their eggs into plant leaves on which a small ball grows with the eggs inside, other species live parasitically in the implantations of other insects. | | |
|
| The cuckoo bee Nomada fucata lives parasitically in the nests of Andrena flavipes, smuggling its eggs in, and leaves its brood as well as their supply with nutrition to the hosts. It may happen that the cuckoo bee larvae eat all the host larvae’s food supplies so that the host larvae eventually st... | | |

| Adult tachina flies feed on honeydew, nectar, vegetable juices, feces or on carrion. Their larvae feed parasitically on all kinds of larvae, pupae and adult insects. 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 in... | | |
