| The fertilized queens overwinter and appear again in the spring. In May, they start nesting, mostly in bushes, but also on rock faces or house walls. They do not nest in dark cavities. The nest is made from a paper-like material, mostly won made of poplar bark. The nest includes brood cells, where the eggs are stored and the larvae develop. The larvae are fed a meat pulp made of insects, preferable Diptera. When the first female workers have hatched, further construction of the nest, and the provision of food supplies for the larvae is their responsibility. A colony can accommodate as many as 200 wasps. The nest can grow to approximately the size of a football. In August additional males and young queens are bred. The young fertilized queens seek out winter hideouts, while all the other wasps die. | | |
| | Vespinae living in colonies build nests in dark caves, trees, hedges or attics. A single state with a queen, workers and drones can comprise up to 7000 insects. Labour is organised - the Queen only lays eggs while the workers are responsible for nest building , nest cleaning, food procurement and feeding the larvae, and the drones are responsible for the fertilization of young queens. To avoid inbreeding, some drones leave the nest and look for females from other populations.
While the old queens usually die in the autumn the young fertilized queens seek safe homes. With the cold of coming winter huge numbers of worker wasps die from starvation and as a result many colony ... | | |
| | | In spring, a nest is founded by a young queen. The nest is made from wood, which is taken from dry or rotten plant stems, chewed and then bonded with saliva. The nests are often found in buildings, garages, sheds or blindboxes. When finished, nests consist of about 50 cells. They have no protective outer surface. Up to 30 workers live in a single nest. At the end of July, the adult females and males of the new generation appear. In September the wasps die with the exception of the fertilized young queens, which hibernate. | | |
| | The females lay their eggs in soil nests or ground nests. Either a new nest is dug, at an average depth of 30 cm, or the females look for pre-existing nests from other digger wasps. In the latter case they are not able to distinguish between already occupied and unoccupied nests, which often leads to violent clashes between them and the owners of the nest in the entrance area. The female digs a nest at which the excavated sand or clay is piled around the entrance. | | |
| | Queens overwinter. They appear in March or April. Bombus pascuorum nest both above ground (old birds’ nests) and below ground (abandoned mice nests). The bees use moss, grass and animal hairs to construct a hollow sphere inside the nest. The interior of the hollow sphere is sealed with wax. The queen then forms a small tub of wax, puts pollen in it and then lays 5 to 15 eggs on the pollen. It also builds a second, slightly larger vessel for nectar (for food on rainy days) . In t... | | |
| | The young ants overwinter twice in the nest which is built in the dead wood of trees and located up to three metres in height. The major part of the nest is under the soil. Some nests are only in the ground. After reaching sexual maturity, the young ants swarm from the nests on warm afternoons in May and June New colonies can be founded either by individual queens or by several Queens. In the latter case the eggs of the queens are stored commonly in a single breeding chamber , and care of the brood is shared.

| | Mating occurs in spring and the males die afterwards. Shortly thereafter, the females start building the nest on bare, dry, sandy soil sites. For this purpose they dig a main gallery, which is up to 60 cm deep and leads into the ground, and into diverse brood cells (incubators). The entrance to the nest looks like a crater surrounded by a small mound. The brood cells are filled with a pulp of pollen and nectar by the females and afterwards they lay an egg on this mixture. A few days later the larvae hatch. The development of the larvae to th... | | |
| ...ets live for 3-4 weeks, drones,1-2 months, and the queen, up to 14 months. The queen, is the only member of the colony who overwinters. In the middle of April she leaves her hiding place and at the beginning of May,starts to establish a new nest. To this end she first builds a honeycomb, which she covers with a paper-like mass made from chewed wood. The queen lays fertilized eggs in this honeycomb. After the larvae have hatched the queen takes care of the brood, feeding the larvae...
...e young female workers have left their pupae, they take over nearly all activities of the queen, who then almost exclusively lays eggs, up to 40 a day in late summer. With strong heat the female workers move their wings, in order to cooling of the nest and thus to save the brood from too much heat. | | |
| | ...bles the pecking order amongst chickens and this can create aggression, which leads to more or less heavy fighting between individual female workers. When this happens workers may sting each other resulting in deaths. If the population of the nest expands greatly and there is no room for further development all the hornets move to a more suitable place and establish a new nest (branch formation). | | |
| | The rove beetle (Velleius dilatatus) is a constant co-inhabitant in the hornet nest. Its stay does not unfavorably affect the population of the nest. | | |
