| ...ueens. 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 wasps become solitary. In spring new colonies emerge from the overwintering young queens.
Wasps have a smooth sting which they use to inject crippling substances into their prey and to defend themselves (even by spraying poison) and this sting can be used again and again. The Honey Buzzard and the Ichneumon wasp are natural enemies of Vespinae.
For humans the German wasp and the common wasp are especially problematic because these live in the most populated colonies. Wasp stings can cause? allergic reactions, often in conjunction with severe itching or pain. The greater danger is from bacteria, such as salmonella, which the wasp carries on its sting and can thus be transmitted to the person who is stung.

| | Common wasp | | The common wasp (Vespula vulgaris) belongs to the genus wasps. It is a wasp from the family Vespidae and is one of the most widespread kinds of wasp in Western Europe. The common wasp is an annual and social insect. | | |

... Dolichovespula saxonica is a species of the genus Yellowjacket. It is a colony building insect. The queens reach body lengths of 15 to 19 mm, the workers 11 to 15 mm and the drones, 13 to 15 mm. The colony can comprise 200 to 300 animals. The wasp has markings on its head which look like a crown? It is found in open countryside and wooded hills, in breeding boxes for birds, hedges or buildings.

| | German wasp | | The German wasp (Vespula germanica) is of the family Vespidae and of the subfamily Vespinae. They are found in Europe, large parts of Asia and some areas in Africa. The German wasp is a colony building insect. | | |
| | The common wasp is found in almost every kind of landscape. In areas inhabited by humans, wasps are considered a nuisance in autumn time. The venom of the wasp may cause allergic reactions. When wasps sting hormones are released and this can encourage other wasps to sting. Due to this a large swarm of this kind of wasp poses a great danger to humans. | | |
| | Black slip wasp | | The black slip wasp (Pimpla instigator) belongs to the family ichneumon wasps (Ichneumonidae), in the order Hymenoptera, the suborder Apocrita and the superfamily Ichneumonoidea. They are widespread and commonly encountered in Europe and North Africa. The black slip wasp reaches body lengths of 10-24 mm. The body is black, sometimes with red legs. The sting of the female is about half the length of the abdomen. | | |
| | Rubytail wasp | | The rubytail wasp (Chrysis ignita), is a species of the genus Chrysis, in the order Hymenoptera, the suborder Apocrita, the infraorder Aculeata, the superfamily Chrysidoidea, the family cuckoo wasps (Chrysididae), the subfamily Chrysidinae, and the tribe Chrysidini. Chrysis ignita are widespread in the Palaearctic ecozone of Europe and West Asia. In Central Europe, it is the most abundant species of cuckoo wasp. | | |
| 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 they spin a cocoon for themselves in the host’s nest and pupate, either immediately, and then either to fly as another summer generation in the sam...
... cocoon for themselves in the host’s nest and pupate, either immediately, and then either to fly as another summer generation in the same year, or to overwinter inside of the cocoon. This assumes that the host larvae overwinter as well. The rubytail wasp is able to synchronize its development with the annual cycle of the various host larvae. | | |
| | Field digger wasps are active from July to October. They prefer to live on roadsides, embankments or sand pits. Sandy or loamy soils, suitable for nesting, are of particular interest. Field digger wasps, and their brood, feed on flies. In addition, they seek out Umbelliferae or animal faeces (eg cow dung). When the field digger wasp sees a fly, it sneaks up, jumps on it and may fall with it to the ground. There, it paralyzes the fly and transports it to the nest. It may also happen that the field digger wasp does not paralyze the caught fly, but ‘kneads’ it until liquid comes from its mouth, which is then eaten by the field digger wasp. | | |

Some examples of species found in Central Europe are: the hornet, Dolichovespula sylvestris, Dolichovespula omissa, Vespula rufa, the common wasp and the German wasp. | | |
